When should diarrhea worry me?

What to monitor at home

A single loose stool after a diet change is common. Diarrhea that lasts more than a day, includes blood, or comes with vomiting, fever, or collapse should not wait.

Puppies, kittens, seniors, and pets with chronic disease dehydrate faster. If you are unsure, start a virtual consult so a veterinarian can help you triage next steps.
