New puppy vomiting and diarrhea: Is it food, stress, or serious?

Updated On September 23rd, 2025

Pet's info: Dog | Boston Terrier | Female | unspayed | 3 months and 4 days old | 6 lbs

I just bought a 12 week old Boston Terrior pup day before yesterday. Up to date on shots, healthy. I gave her some canned dog food and a few hours later she vomited and has diarrhea. She is still wanting to play. Could it just be the food?

it can be related to the food or the stress of a new home and environment with new people. Try boiled chicken and rice for now. If the stool turns bloody or she stops eating, then I would get her checked right away.
