My puppy ate chocolate cookies, now vomiting & red poop. Vet?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | 5 months and 24 days old | 16 lbs

Hi, I have a 5-month-old puppy (Benji) & yesterday he got a hold of some chocolate chip cookies probably 1 or 2 and he seemed fine, I took him out for a walk then came back and gave him plenty of water. Then just this morning he woke up and he started to vomit. It wasn't much, just plain brown vomit. I took him out again after he had breakfast and I noticed that his poop was a red like diarrhea so I'm wondering if I should take him to the vet or if he will be ok? He does seem okay and is active

I doubt the number of chocolate chips in 1-2 chocolate chip cookies would be enough to cause chocolate toxicity, however any rich food can potentially trigger vomiting and diarrhea in dogs. If he seems otherwise fine you can monitor him during the day: I would only allow him to drink small amounts of water at a time and would not recommend feeding until this evening. If he vomits again, or if he has more diarrhea that has a red tinge to it I would recommend seeing an emergency veterinarian.

    A small cookie may not cause serious toxicity. You may see some gastrointestinal upset such as vomiting and diarrhea. You can manage these with a 24 hour fast followed by a bland diet in small, frequent amounts until symptoms resolve.
    Symptoms of concern include hyperactivity, rapid heart rate, tremors or seizures. These should be addressed by your veterinarian.
