Our 4 month puppy was playing so aggressively with our family of 4 I was seriously considering sending her back to the breeder. It didn't seem like normal puppy play but I had never had a dog. We had a dog trainer come to the house when our puppy first came home to get us started with some general commands which she followed very quickly. By the trainers second visit our puppy had begun playing very aggressively and I actually had my kids show the trainer all the kids ripped clothes. The trainer gave us some more tips on controlling this play and the biting but it started to get even worse! After our vet experienced our puppies unruly behavior she confirmed that it needed to be dealt with and quickly. She gave us a list of preferred trainers and said she couldn't attest to all but she knew dog owners that had had great experiences with Bark Busters. Luckily Mark had an opening the day after we called. We were desperate and hoped he could start us on our way to enjoying our puppy instead of being terrified of her. After the first 30 minutes of training I couldn't believe the results. Mark spent so much time with us and never made me feel like he was in a rush which the first trainer we hired did since they worked on an hourly basis. This level of time is absolutely crucial for getting the training down. Believe me when I say you will pay more for a trainer that is charging by the hour because they will need to come back often. The first visit with Bark Busters will be 2 and 3 hours and yet it felt like it flew by. I am happy to say that it's been 24 hours since Mark stepped in our door and I can not believe the change in the house. I am now walking around signing "Leader of the Pack"!!!

I volunteer with a rescue and last year we hired Mark to work with a dog that acted highly aggressive to other dogs. It was so bad that he could not come to adoption events for months and honestly was one of the worst cases I had seen. Once we got him into a foster home, Mark started working with the foster parents and after the first session, the improvement with Ollie was nothing short of remarkable! Not only could he come to the adoption events without problems but he is now living in a home with another dog and going on play dates every day with the adoptor's mom (who has several dogs). The whole transformation was amazing! After we hired Mark, it was only a matter of a few weeks before Ollie got a great adoption application. We have now just hired Mark to work with another dog and I am completely confident that we will see the same great results. The methods Barkbusters use -- all gentle and easy to learn -- are so effective. I wish we had used Mark and the other trainers years ago with some of the dogs that had some "issues". We have had great success with their other Barkbuster trainers as well but Ollie was such a hard case -- or so we thought --- but Mark showed us what a great dog he could be (indeed was) with other dogs.

Mark was very patient and understanding with our particular needs of our two dogs. He has so much previous experience that has allowed him to understand just about any situation you throw at him with your dog. Through the BarkBuster methods, he has helped my husband and me understand the importance of following through with practicing methods. Mark is really a trainer for trainers versus dogs and helps owners understand the dogs perspective of their actions. While we have only experienced the first day of training, I expect awesome results moving forward if we practice the skills we learned. Thank you Mark for your help bringing our furry family closer together. Highly recommended

Mark was excellent with us and our dog Rhys. Rhys is a generally nice dog, but needed some obedience work. More importantly WE needed someone to teach us how to give Rhys the guidance he needed. The results were immediate. Shockingly immediate. Mark explained our role very thoroughly so we not only were able to successfully guide Rhys, but we understood what we were telling him. Rhys seemed a little mollified after our first session, but as we practiced our guidance he settled into his role as the submissive dog and seems calmer overall. I highly recommend Mark's one on one in home training. We are beyond pleased with the results!

This training is the real deal. Mark is the best of the best when it comes to temperament reading and getting to the root of your problems on the initial visit. You can argue that website tips and books alone suffice until you see just how effective Mark’s situational awareness in your home actually is. Don’t even think of taking your pet somewhere else. You’ll get buyers remorse and end up paying Mark later on anyway so do your pup(s) a favor and get it right the first time.

Mark is absolutely incredible trainer. My dog Shopia was really reactive on leash with other dogs even just passing by other dogs from a distance. She was a rescue and was abused with no socialization. I thought there was no hope and Mark came in and saved the day. She now goes to doggie day care and even thinking about bringing in another dog! Mark is truly an amazing trainer and anyone with issues with their dog needs to go with Mark!

We were looking for a dog trainer to help us with leash training and dog aggression. Ruby was the best dog except on a leash and when she saw other dogs. It was very embarrassing how she turned from a sweet dog, to people moving away from us in fear from her crazy behavior. We learned some things from another trainer, however we could tell he was overwhelmed and at a loss with Ruby. We wanted to trust the next trainer's knowledge so we took our time in finding the right person. We have NO regrets with Mark!! He certainly knows his stuff and after just one visit, we have a whole "new" dog!! She listens to our commands, follows on a leash without using treats and without pulling at all. Most importantly, when she sees a dog, she remains focused on us and not the other dog. We can even take her camping now and have no worries how she will be!!! Thank you Mark!!! We are grateful for all you have taught us!

This is our second time using Bark Buster's. Twelve years ago we used BBs for our Sheltie to correct barking at our fence line and at the front door. We were totally amazed that the issue was resolved after just one visit and brought peace to our lives. Fast forward twelve years and we now have a Pomerian who barks at the front door, the vacuum, brooms, the fence line, and everything! I called Bark Buster's again and we just finished our first session with Mark to once again outstanding results. Mark spent a little under 3 hours with us working on the barking in various situations. Shortly after Mark left I was actually able to vacuum my kitchen floor with no barking! I then took him outside and our dog heard someone over the fence. He barked once and I corrected him to the dog's immediate silence. Thank you Mark for giving us peace! We look forward to our next session to work on barking in the car.

Mark was incredible! My dog went out on our balcony for the first time EVER without barking her head off during the first training session! She waited for us to go up the stairs, didn't bark for the doorbell, and waited politely for our guest to come in before saying hello. All in the first training session. Amazing. I just wish I had know about Bark Busters sooner!

I am just amazed to see the instant results after just our first meeting. My dog Diesel is a rescue that came from a no rules background and needed help with all his manners and learning the rules. I tried doing some training on my own and found little to no results in it. Within the first 10 minutes of our meeting I was already seeing changes in Diesel. Mark teaches you how to think like a dog to be able to properly communicate with your pup. Diesel pulls on the leash especially when his squirrel friends are in sight and loves being an escape artist. We had him outside on stress free, no pull little stroll and for the first time someone was able to enter and leave my place without Diesel embracing his inner Houdini! Thank you Mark for your magical training techniques and I'm looking forward to our future sessions.

We are repeat customers of Bark Busters. We have/had three Jack Russell Terriers all with separate issues. Mark was there to help us with our adopted 5-year-old JRT that was abused and neglected. Buddy had fear aggression, never learned to walk on a leash and would bark incessantly when seeing another dog. After two years of help from Mark Buddy became "normalized" as much as JRT's can adapt. Despite all kinds of problems, Buddy gained another 10 years of life, and Mark was always available for help. Last week, we brought in a 26-week-old JRT from Lubbock Texas. Jacey was always outside in a pen with family. There was nothing but land, pump jacks and sage brush. With Marks' help, we have her house trained within two weeks, and she is well on her way to listening to commands. We know Mark will be there all along with her development. When he says a lifetime guarantee, he means it.

Mark is amazing. We first worked with him in 2016 with our dog Spot. She was a rescue and shortly after we adopted her I tore my ACL so we had to develop some good dog manners really quick. Mark in his first session taught us to speak dog and with our newfound vocabulary we were able to come to an understanding in the home. I could safely navigate the stairs without pushing which was my biggest concern. But in addition he helped us to deal with aggression towards our Son's musical instrument practice and some bad leash behaviors. It is a year and change later and we have adopted a new puppy and while we were trying on our own to apply our lessons we decided to bring Mark back and we are really happy we did. There were parts of our doggy vocabulary that we had forgotten and we needed some new conversations to work with such a young puppy. I will say that there isn't any magic just solid tools that require you to commit to learning to be the best dog owner you can be. Mark isn't going to suddenly change your dog's behavior, he is going to teach you how to work with your dog so that it understands you. This is a huge difference from many other types of training where you are trying to make your dog understand human behaviors.

We called Mark from Bark Busters after one of our neighbors recommended him to us. We have two Vizlas, both 17 months old and we were looking to get some help to get them trained in basic manners. We felt like our dogs were getting the reputation for being the dogs that bark, lunge at others when we are walking. Previously, we have had our male dog, Rex trained in basic puppy training but it was a waste of time and money. So we went into this slightly unsure. Mark comes to the home and trains you to handle your dog where it matters the most, at home. Our first meeting resulted in him having us work with Rex and Rue at home in areas that needed improvement (there were a lot of areas). We were completely shocked to see the change in our dogs' behavior in just one setting. They were different dogs in just one day. There is no clicker, no treats, it is training the dog to realize who the leader is! We are beyond impressed! Bark Busters services are for a lifetime so if at any time there is a concern they will come and help you out. We have had two sessions with Mark, one for indoor behavior, one for the walks and we look forward to his third visit in January. We highly recommend Bark Busters if you are even slightly interested in training your dogs.

Incredibly impressed. We interviewed a few dog trainers. It was an immediate decision to hire Mark upon meeting him. I didn't want to use pain collar training, I wanted those 30,000 year old tried and trusted human-canine domestication / training methods with a trainer who understood canine psychology. Mark made training so simple for us to understand and gave us training for behavioral issues we didn't even notice before. Fascinatingly, my dog was responding to the natural training within the first day, and, most importantly, after Mark left. We are very happy with what we learned.

Outstanding training! I have recommended Bark Busters to all my friends and family who have dogs. I first met Mark 11 years ago when we brought home a very rambunctious black lab puppy named Buddy. Mark worked with me and my 12 year old son to train Buddy. The combination of Mark's ability to custom fit the Bark Busters training methodology to our dog and family's needs is off the chart. Buddy was a very well trained dog because of the advice and training methods they gave us. We always received compliments on how well trained he was. Unfortunately our dog passed away from cancer last year. We just brought home a 9 week old puppy and I had forgotten how much work it is to train a dog! My first call was to Mark so we could schedule our first training session. I just finished up the training session and it was so helpful. To get the practical guidance and training specific to the issues we are having was invaluable. My wife and I now have a game plan on how to handle the issues we are having with our new puppy, Dover. We also love the fact that Bark Busters is available to us throughout the life of the dog when various other issues crop us. And believe me, they do crop up and we can rely on guidance from Mark at Bark Busters to guide us on what to do.

Mark has a calm, non-judgmental way about him which allows us to relax and share freely with him in an effort to get to positive results. When one tool wasn't working as well with our dog he had another option at the ready for us. We value the training that we are receiving to help our puppy be the best dog he can be. Thank you Mark!

Signing up with Mark at Bark Busters has been one of the best investments we've made in years. His intuitive read on dog behavior and patient training of dog owners have made significant improvements possible in the behavior of our two rescued terriers. Both of them are smaller dogs with some fear-aggression issues and a noisy barking habit due to separation anxiety. We signed up for a lifetime package and got some great early changes implemented within our first 3 meetings. More than a year later a new issue came to the forefront and we were able to call Mark again and have him over. His advice is consistent and not harmful to the dogs. You can tell when he walks into the room that the dogs know exactly who is the dominant figure - and he helps us translate that to our dogs!. In that way, he speaks their language and helps owners to understand how many bad behaviors are really stemming from confusion over their pecking order in the home.

We adopted Myka as an older dog. She was coming into our family needing to be great with kids and other dogs. We quickly discovered that she had dog aggression and walking her was a very stressful situation. She wanted to attack any dog that she could see. We contacted Mark because she came with the lifetime training. When Mark first arrived, I was leery, but desperate to try anything! Mark worked with us for nearly 3 hours and by the time he left that evening we had a completely different dog! The next morning, my walk with Myka was much easier. The techniques Mark gave us have calmed Myka down and have made our relationship with Myka extremely enjoyable. We live in a very dog friendly community and have young children. If it were not for Mark's expertise, we would not have been able to keep Myka as our family pet. We are extremely grateful to him for these easy to implement (AND KIND!) techniques!

We rescued Lance a couple of weeks ago. He is a 2 1/2 year old black Lab. Lance had a lot of bad habits such as jumping up when people came into the house. He counter surfed, and showed aggression with toys. We were a bit skeptical about bark busters, but they came highly recommended by our Vet. Mark came and after A little over 3 hours we had a different dog! Lance now knows the consequences (nothing physical or harsh) if he jumps or counter surfs. We can sit at the dinner table and eat with Lance staying in another room watching us. Lance doesn't pull while walking, and he has learned to stay seated when the door bell rings and he doesn't approach a guest unless invited. Mark showed us how to stop Lance from running up or down stairs ahead of one of us. We will continue to do our homework, but without Marks instructions we would not have the obedient dog that we have now. Thank You Mark!!!

Our newly adopted young dog was very affectionate and smart -- and loud!

Mark was so reassuring and helpful, and taught us how to communicate with Sienna so she could just relax and be her sweet self all the time. Complete turnaround after one visit! The indoor barking was gone. Our subsequent trainings helped us with her leash manners and being more responsive to commands like "Come!" This approach works!

Our nine year old blue heeler-pit bull mix (cattle dog/working dog breed) rescue, had, since he was a puppy chased his tail obsessively. After our second child was born, his behaviors escalated and became more aggressive with sudden movements and loud noises. It was obvious that we were out of our depth, so we asked Mark to come in. His calm demeanor, non-judgmental approach, and tremendous professional competence were immediately apparent. We learned during the first visit both the philosophy behind the training mode and practical steps to take. The immediacy of the changes in our dog was the most impressive. By the end of the first visit, our pup was calmly asleep at our feet under the table as we wrapped up with Mark. He scheduled two additional visits and has since made himself available for any on-call situations. Our dog's anxiety oriented behaviors have decreased by 90%+. We have actionable tools and tactics to correct him, and we know how to set training scenes to further his development. Mark's expertise is the reason for all of this. The cost is not insignificant, and like so many situations, you get what you pay for. The fee is for the lifetime of the dog, but we would absolutely pay again to achieve the results we've seen in the past two months.

Before Mark came to access our beloved dog Rocky a 5 and a half month old chocolate labrador retriever, Rocky had made our life very busy and frustrating as he would not listen to us and be hyper energetic and always want to run around and keep jumping and barking. Once Mark took Rocky as a student in 45 min he had given us and Rocky a sense of confidence we needed in each other. He has not barked since in the last 3 days at anyone, he is sleeping and playing well and is able to spend time with us as a family member and not a rowdy street dog. What I love about Mark is he listens to our concern patiently and addresses it. He doesn't do any treat training. I spend my best money on my buddy Rocky by hiring Mark. Thanks Mark.

Mark Renshaw from Bark Busters came by for our first training session and I can already see a difference. By simply teaching a new "command" and establishing dominance i can see that "Zoe" will be trained to the level i want. Mark also left us with great exercises that are easy to do and reinforce everything he taught us. Mark has a very understanding and easy going personality which makes the training easy for both the dog and owner. I would recommend Mark to anyone who is looking for help with their dog. I would like to add to this (same day a couple hours later) - i just took my 5 month old Doberman puppy on her first walk with me after Mark left today. One of my main issues was her walking on a leash and not pulling. Mark only worked on walking today for maybe 10 minutes but we had already established the "BAHHHHH" training (If you don't know what this means please hire Mark, its a great way to train your dog) and after her 3rd "bahhh" she was walking PERFECT. She never left my side and never pulled again. I was not expecting this and i know she is not 100% perfect already but i am amazed at how quickly Mark has already impacted my dogs behavior. After consistent time spent with Zoe this method will have her completely trained.

We can't thank Mark Renshaw enough for his help getting our dog Annie's walking habits under control. Annie used to bark non-stop during walks, and lunge towards squirrels, motorcycles, trucks, and anything else she either considered to be a threat or prey. It started to become embarrassing as neighbors looked on with surprise or disgust. It took Mark just one 3-hour training session to get this behavior under control - using the techniques that we were taught, we now get regular compliments on how Annie carries herself. Most importantly, we (and Annie) are a lot happier on walks!

We were referred to Mark by our vet after trying a couple of other trainers. Other trainers could work with our puppy, but few could transfer those skills to us. As my wife had been traumatized by a dog encounter as a child, we had some very specific challenges to overcome. Our puppy was beginning to appear aggressive and unmanageable to us, and we began to wonder if would be able to keep him. Mark was able to empower my wife so she had more control over the puppy, and had the confidence to feel safer when she and my daughter interacted with him. Our puppy's demeanor and interactions with us changed right away. He became more gentle, and surprisingly, appeared to be more comfortable in our home.

I was very impressed with Mark and the Bark Busters program. Mark really knows and understands dogs and the program worked very well for my dog! I love how it's a lifelong program. That gives me peace of mind, knowing that we are covered if any other concerns or issues arise. Mark came with his toolbox of resources and ideas, and worked on any concerns or issues we had. He sat down with us to chat and figure out where we wanted support and help. From there, he drafted up a plan and we started working! Mark has a ton of ideas, so if something didn't work for my dog, he tried another idea and another, until we found one that was right for her. He is very positive and a strong believe in praise and love for positive reinforcement-which I really love! He was available by email and phone if we had any questions while we were doing our "homework" in between training sessions. There was a trick that I really wanted my dog to master, and he helped us with that as well! I highly recommend the Bark Busters harness. It had made all the difference for us when walking! If you have a pup who is hard to manage on a leash, you should definitely get this harness! I recommend Mark and Bark Busters if you have any training needs for your pup. He is very knowledgeable and you will definitely see improvement right away!

Mark has done wonders with our 2 year old pup, Sansa. After just one training session, she was acting like a new dog. We could not be happier with the results, and are so very thankful we have Barkbusters to back us up if we ever need some more help!

Mark is an amazing dog trainer! We started working with him when our Labs were just puppies and since that time, they have learned to listen and obey our commands. He truly loves working with dogs and they respond to his methods instantaneously. There is no aggressive behavior towards the dogs, everything is taught in a very humane fashion. He explains every behavior and how to correct it in a way that is attainable and comprehensive. I have several friends who have used him and they were all very satisfied.

Mark has done an amazing job with our puppy. After his first visit, it was like she was a different dog. Some of the changes from the first visit: - no longer pulling on leash - no longer running to front door to greet guests - drastically reduced jumping on visitors - coming when called Changes since the 2 following visits: - she's mastered sit and stay - recall out doors - we can even play fetch with her off leash Overall she's the most well-behaved dog I've ever had, and it's thanks to Mark. I can't believe how far she's come - and she's only 9 months old!

Mark was great. By the end of the first session we saw an incredible difference with our dog (8 year old shih tzu). She calmed down dramatically and her incessant barking was almost completely eliminated. The training methods were effective, simple, and easy to implement. We would highly recommend Mark and Bark Busters to anyone looking to see dramatic changes in their dog's behavior.

We had a great experience with Mark on his first visit. We needed to get our 7 month old adopted Belgian Melanois/GSD puppy manners and most of all to get along with our 9 year old cat. Roxie was constantly barking at Jag and the house was at war! Enter Mark and within our 3 hour session Roxie and Jag were in the same room! They are not best buddies yet, but it has only been a short time and we have been working on our homework. We look forward to peace in our home and having a well behaved puppy soon. We can't wait to see what we ALL can learn together at our next lesson. Mark actually trains you to train your pet. Thanks Mark!

We were in deep trouble. We have an aggressive 100 pound guard dog, and 2 smaller rescue dogs with all kind of issues. It took us awhile but we realized that we need professional help. Mark called and we talked in length before his very first visit, so he came prepared. He has an impressive knowledge of dog behavior!!! I believe he had a pretty good idea of what's going on in our home within an hour. He listened to us patiently and watched us interacting with our dogs. Then he taught us how to communicate with them. By the end of our first session I felt like I learned a new language that I can use with my dogs. We are at the beginning of our new life as a pack:-) but 4 weeks into it, we had no incident of aggression and although we still have a long road ahead of us, we absolutely see the end of the tunnel! He'll come back and we'll continue on learning and practicing:-) I can't imagine that there's a better person/trainer I could recommend.

Our dogs had terrible barking issues. They barked at every person and dog who walked by our house, they barked at animals on TV, they would go crazy barking at other dogs when we went for a walk, one of my dogs even barked at airplanes overhead. After one visit with Mark, the barking had almost completely disappeared. Mark has showed us how to be the pack leaders with our dogs thru voice commands......the results have been fantastic!

After our first training season with Mark our lab Abby was a much better behaved dog. In the past Abby had us trained to get up two and three times during the middle of the night just to take her outside. Now with the training aids Abby does not wake me up at all in the middle of the night. She has learned that I am the pack leader. Mark is a great trainer!

We were having aggression issues with our one year old springer spaniel as well as some bad behavior problems like jumping on people and pulling on the leash. We were assigned to Mark Renshaw and immediately saw positive changes in our dogs demeanor. As he explained, the more our dog saw us as the leader the less apt she would be to show aggression and test us. I only wish we had persued her training earlier. Mark's knowledge of dogs and training definitely gets all the credit!

Milo spent the first 5 years of his life tied up in a backyard or in a shelter. He had zero experience living in a house. To make matters worse, I had zero experience with the bully breeds. The first few months were a bit of a trial. Mark came and straightened us both out. Mark spent hours teaching me what I needed to do and gave me great advice. I followed it all and Milo (who is clearly a genius) immediately was a better dog to live with. It turned out our biggest challenge was my lack of patience and general knowledge. He had several challenges and Mark had solutions for all of it. The Bark Buster method is perfect for the bully breeds, but we had to find the right balance since he had previously been abused. Mark's approach is perfect for someone with limited dog experience or just wants to learn a better way. There was so much I didn't know. Of course, I didn't know until Mark pointed it out. Now I'm the pack leader and Milo is doing great. We couldn't have done it without Mark.

I didn't really have high expectations for this training and questioned the ability for anyone to change my dog. Especially my dog! But, I have to say, even after one session the difference Mark's training made was dramatic. It was like night and day. My dog went from pulling his leash to walking beside me, from bolting out the door to waiting for my command and from barking at the UPS guy to, currently, a small whine. There's still more work to be done which is why I got the lifetime package but this was and is one of the best decisions I made to make my life with my dog fun. Highly recommended!

Mark came to the training prepared and Helped us with our Lab overcome fright of the stairs. Something had happened that made him not want to climb the stairs. Mark worked with us and Puck and gave us homework to continue. Within a few days, Puck was back climbing the stairs with out hesitation or fright. We are a return customer to Mark. In the past he has helped us with a German Shepard and an English Mastiff. Like our Lab, Mark helped us with their situations and it lasted.

We adopted Daisy (boxer/hound mix) from a rescue organization. She was a good dog inside the house but horrible when we tried to walk her. Rabbits, squirrels and deer triggered her prey instinct. It is hard to describe her vigorousness and perseverance (pulling and jumping for nearly a block) when she saw prey. We were ready to return her. My wife called Bark Busters and Mark came out on a Thursday. We had arranged with the rescue to return her that Saturday. Mark's success in calming Daisy's response to prey was incredible. Daisy walked like a different dog. Thursday evening I emailed the rescue group and told them we were keeping her. We still have her and are glad we do. Mark saved our dog for us.
