...stopped. One day later his? sister developed vomitting and diarrhea. The vomitting has stopped but the diarrhea remains for three days and now has frank, red, mucusy, blood in it. We made her ground beef with rice. She only ate a small amount and would rather eat the hard food. I didn't giver her any but she stole a small amt from her brother. I thought this may be related to the Iams I bought at Big Lots (exp. 2011) but today, my mother's dog started having vomitting and diarrhea. My dog's were staying over there. There are no appts. available at the vet today. What do you think?
