Hi there! It sounds like you're dealing with a bit of a messy situation, and I’m here to help. Diarrhea after introducing a new food, like hydrolyzed protein, can happen for a couple of reasons. For some dogs, any diet change, even when it’s to a special formula, can cause temporary tummy troubles. Hydrolyzed protein diets are typically easier to digest, so it might be surprising. However, it could be that your dog is adjusting, or there might be a sensitivity to another ingredient in the food.
To help manage this at home, make sure your dog stays hydrated. Offer small amounts of water frequently and ensure they have easy access to fresh water. If they’re otherwise feeling fine—no vomiting, lethargy, or loss of appetite—try feeding very small portions of the hydrolyzed food more frequently to see if that helps ease their digestion.
Keep a close eye on any additional symptoms like blood in the diarrhea, repeated vomiting, difficulty walking, or if your pet seems very weak or in pain. These signs can point to a more serious issue that needs immediate attention.
If the diarrhea persists for more than a day or two, or if any of these worrisome signs appear, it’s best to consult with a vet. I recommend booking a video consult with Dial A Vet. It can be helpful to show the vet exactly what’s happening and get personalized advice for your furry friend’s needs.
