Looking for recommendations for an exceptional dog trainer. My nearly 5 month old purebred beagle puppy disobeys constantly. I house trained him in 2 weeks and he listens when told to sit, but he bites a lot,I chews on anything he can get his mouth on, and completely ignores all other commands (stay,no,drop,come,down) I've been reading/watching everything on this topic and have tried everything as well, seems nothing takes! I have two small children so it's very important I break these bad behaviors immediately. Any help would be greatly appreciated. Thank you.
