Millie went to the vet last week and was given the DHPP, even though my mom questioned it. I don't think they really told her what she was getting either, because she thought it was just the parainfluenza vaccine. Last night she was vomitting, and had diarrhea, and today she's refusing to eat. She wouldn't eat her food this morning or tonight, I tried yogurt, Old Mother Hubbard Charcoal bones, Banana Water Ice, and a liver treat. She refused it all and let Max eat it right in front of her. Usually if she won't eat something, she never lets him have it. If he tries to steal it that usually gets her to eat. She also allowed me to cut her nails. I decided to try it, because I knew it would tell me if she was really feeling bad. Last time I tried to cut her nails she tried to bite me. Today she just let me do it. That has me more worried than the not eating. Is it possible this is from the vaccine, or would it have to be something else?
