Hi everyone! I am a new member to the forums and also new to owning a Berner, but not dogs Our pup Champ is about 12wks old and a BIG boy. One of the main issues we are having with him is very bad nipping/mouthing. It is so bad that he draws blood on my 4yr old and myself. You cannot have a toe, or any body park hanging off the couch of he will bite it! He also bites as we are just walking in daily life. We are on constant guard of being nipped by his sharp puppy teeth. We have tried yelling "no", "ouch", putting a toy in his mouth and time-out. We currently do not use a crate, but I'm starting to think I should get one. I just never had luck training a puppy with one. Any suggestions for a new Berner mom? I have not seen this level of mouthing on other pups before. Thanks!
