My 9 week old puppy has turned vicious!
I recently got a toy fox terrier puppy as a gift from a loved one. She is from an independently owned pet store from a well known man in town. He claims the dogs are from lagit breeders in the area and are not inbred. I have taken her to get her shots. She has gone twice and the second time she got two shots. One was the distemper. After she received these, her mood has changed drastically. You can't even hold her without her growling and biting your hands. She is very small, about 2.6 pounds but her teeth are like little needles and it hurts really bad. She also ate some rabbit poop in the yard more then once and I couldn't get it out of her mouth before she swallowed.
My question: What could be causing this drastic change in her personality? Is it the shot(s)? And will it get better or has she picked up a disease from outside?
