How old is your furbaby?
Could your pup have been mistreated when you were not around? Something caused these changes.
Always leave "legal" stuff to chew on.
Have you worked with a trainer who understands behavior modification?
I did when one of my dogs became aggressive to everything that wasn't human after he was attacked by a Rottweiler. He even pulled a friend's parrot out of a tree! (We got to the bird and he was OK.) My babe did calm down after a few sessions.
Best of luck. |
