My boyfriends dog is a 1 year old female German Shepard and doesn't want to do I was wondering if there is any vitamins or medicine I could give her or what should I do?

Is the dog eating and drinking properly? Has the dog been checked for worms or ticks? When was the last time the dog saw the vet? Are the shots up to date?

By not wanting to do, do you mean poop?

Are you feeding him any types of human food? Have you done a dog food change? Has he eaten any thing he shouldn't have? Do you feed him raw hide?

Sorry to answer your question with answers, but we need a bit more info to help.

Thanks! :)
