Most behavioral issues are learned based on both experiences and environment. That’s why in home dog training is so effective because this is where most behavioral issues occur because it’s where your dog feels the safest. Because your dog can’t speak English and you can’t “speak dog” many miscommunications occur. At Bark Busters, we can teach you how to communicate with your dog in a language he understands.
Does your dog bark constantly when it’s not appropriate?
Does your dog get stressed when you leave?
Does your dog chew and dig out of boredom or otherwise?
Toilet training your puppy should start as soon as the puppy is home with you.
Does your dog continuously repeat certain behaviors more than normal?
Is your dog aggressive toward humans or other dogs?.
Does your dog pull on his leash during a walk and try to walk you?
