My 4 Month old Bernese Mountain Dog is having a really hard time with realizing her bite inhibition. She kinda loses her mind when she decides she wants to play. She will bark then start to bite me. She bites excessively hard and is hard to get to stop. Any suggestions anyone else has would be great we have been in puppy school. She is getting better but when my Grandkids start running around she bites after a bit on the little one also.
