Hello I rescued a yorkie from being put down on July 3rd he was rescued by a lady at the grace foundation she picked him up from the manteca shelter, we met him n fell in love. He was so sweet he would lay next to us n let us hold him dress him n everything. We took him to the vet on July 7 he got his DHLPP 1st series ...n they found out he had a wound on his testicles n got him on Clavamox antibiotics n w/ a cone so he wouldnt lick himself he did fine On July 17 took him to get rabies shot n 2nd DP vaccine he was moving around alot when they gave it to him and I had to hold him tight. For 4 days he had a limp and layed around for 2 and would not want us to hold him nor touch that side of his body right side shoulder paw area. Its now Sunday exactly a week he is walking fine eating fine but he still nips at us if we try and hold him or touch him in that area what can I do I am desparate i want to hold the little guy but he is so scarred how long can this behaivior last what can I do? Today 7-27 a freind cam over tried to pet him and he bit her I dont want to have to give him away but I am getting no where tryinh to reach out for advice any out there? PLEASE

It is probably pain, fear of pain, or a behavioral issue has set in.

I'd talk to his vet about putting him on some pain drugs and see what happens. If it continues, then training comes into play (maybe including hiring a trainer).
