We are the owners of a 5 month old Berner. We picked him up at 8 weeks from the breeder. He is pure bread. We have never had a Berner before and this is our first puppy. We have a young active family. We are struggling raising him and could use any help and suggestions. Due to COVID Our obedience Class was cancelled and he hasn’t been able to socialize with other people or dogs. Quite honestly he is a terror. Help!
