Well thus far, the vet won't check for coccidia...he said that the vomiting ruled that out. Everything I've read says the opposite. The breeder informed me that he's had a coccidia problem before and to have her checked. As for the parvo test, my puppy had the runs when I got her and she wasnt really eating. Then two days later she was vomitting. She was still playing and once she got to the vet, the tech said she didn't have a fever...that's why I was curious about the false positive. The vet said their's no chance...but I'd heard otherwise from the vet tech at a different clinic. I'm lost.
