My dog vomited after new food. Is it an emergency or should I wait?

Updated On September 23rd, 2025

Pet's info: Dog | Great Pyrenees | Male | 120 lbs

Vomited 3 times last night about 1-2 hours after eating/drinking. He's keeping down ice today and I just tried chicken and rice about 30 minutes ago. So far no problem. We did try a new food about half and half with old food starting Saturday. He had half normal stool half watery yesterday. No bowel movement today. Our vet would like to see him but his won't get into the car. We have been working on training but we aren't there yet. No panting or excessive salivation. Emergency or wait and see?

If he's keeping the chicken and rice down it may be that he has some digestive upset going from the food change. It's possible there is an ingredient that doesn't agree with him with the new food, or that you are transitioning too quickly. If he's able to keep down the chicken and rice and is otherwise acting normal (no longer vomiting, etc), you can try with the old food once more for a few days, and then gradually increase (10-20% new food increments) over a period of 7-14 days to see if that prevents it from recurring. However, if the vomiting continues, he doesn't keep down the chicken or rice, you see blood in his vomit or stool, he's painful or seems in distress, then it would be best to seek veterinary care ASAP to rule out any more serious issues causing it.
