My family just went through a round of a summer cold and this morning our 6 month old Aussie had two loose stools and even vomited a little bit of stomach acid. Shes napping like she does around this time everyday. Ive been keeping an eye on her. She still wanted to play a little while ago but I kept it minimum, I didn't want to upset her stomach any more. She drank a little and kept it down but she still isn't seeming to want to eat. It's really hot today and I'm wondering if that may be stressing her a bit. I just want to know if this is serious enough to rush her off to the vet or not. Any comments and help would be much appreciated.
