ok, so my little brother brought over a pup he got from the local pound a few days ago ( he brought her over the same day he got her) and now Niketa is sick. She has watery stools and it smells off so Im freaking out. She still is eating, drinking and being her playful self, but Im stressed just for the fact that she dont have all her shots and the vet told me that in like the pit breed they have a harder time fighting off parvo. anyone have any info on this? could it just be something she ate?
