My dog has yellow diarrhea, won't eat, and is subdued. Vet needed?

Updated On September 23rd, 2025

Pet's info: Dog | Border Collie | Female | spayed | 3 years old

Jess is a border collie and started with yellow diarrhoea on Friday as we left for holiday. Still has diahorrea today and didn’t want dinner, should the person looking after her take her to the vet? She has been ok in herself going for a walk but subdued when back home, could it be an issue the vet needs to see or can it be left another day, the subdued part maybe pining for her owners possibly?

Thanks for using Petco Pet Education Center, formerly Petcoach! Diarrhea and inappetence can be observed with conditions such as colitis, gastroenteritis, dietary indiscretion, intestinal parasites, among many other possibilities. I recommend that you have Jess evaluated by your veterinarian for further assessment and treatment. It is concerning that she is not eating. They could potentially take radiographs to check for anything that could explain her decreased appetite and they may choose to check for parasites and to start medications for diarrhea depending on the results. Good luck! Hoping for a speedy recovery!
