The vet said he thinks it's just stress.. he tested for parvo and is was negative
He gave her an antibiotic shot and sent me home with something to help with the diarrhea and another antibiotic, as well as Hill's ID soft food (she ate a whole bowl full when we got home
) So I think everything should be fine.. she's in the other room running around with Carson trying to bite his tail
(it's not docked)
Thanks for all of the concern and advice.
