Veterinary advice recommended today — For most cases, follow the home-care steps below and call your vet the same day if warning signs appear.
A single soft stool after a new treat is usually harmless. Diarrhea that continues, contains blood, or comes with vomiting or low energy needs veterinary advice.
Contact your vet if any of these apply:
Make sure fresh water is always available. Offer a bland diet (boiled chicken and rice) in small meals and reintroduce normal food gradually once stool firms up.
Your vet may check stool for parasites or infection and may recommend a gut-support diet, probiotics or medication.
For puppies, kittens and senior pets, call your vet the same day. For healthy adults, contact your vet if diarrhea lasts more than 24–48 hours, or sooner if there is blood, vomiting or low energy.
No. Many human anti-diarrhea products are dangerous for pets. Plain, bland food and water are the safest home steps until your vet advises otherwise.
