We have a 9 week old Berner named Koda, he is a great puppy and adjusting well. a few questions I have How do you teach your puppy to stay down? He is jupy when excited (which is cute not but we don't want to encourage it as it wont be cute when he is big?) Walking, when we put him on a leash and take for a walk he usually sits or lays down and doesn't get very far? Tips to encourage walks? Nipping and chewing, biting? He is teething something fierce right now and chews or bites a lot, any tips that worked to stop this? Barking? He is pretty quiet but barks when i'm getting his food ready or the odd time, we know barking is how dogs communicate but also don't want to encourage a super loud dog? What were some favorite treats of your puppies?
