Aggressive, disobedient and hyperactive dog.

[KentuckyGSDLover]

I have a dog just like this. Reactive, so hyper that no amount of anything is ever enough, and also tail chases when she's even more nervous/stressed. She self-pets, if you ignore her she drops the Kong on your foot, chews on you, paws you, etc. It's like having a pesty, inappropriate little kid in the house. She's not dumb - she has trained to do many things. It seems to be a personality disorder. I've come to think this dog as mentally ill. If you find an answer, other than the obvious things that I've tried, let me know.
