Why is my dog throwing up after eating, drinking, new food, or walks?

Updated On September 23rd, 2025

Pet's info: Dog | Miniature Poodle | Male | neutered | 2 years and 1 month old | 24 lbs

I have a ~2 yr old rescue miniature poodle mix. In the last week, I've noticed that he has thrown up after both eating and drinking water. Normally, we go on walks and he eats right before or after, so not sure if this could be related or not. Also, I did switch his food this past week as well. He's an active, lively dog who always has an appetite, so he isn't showing any other symptoms. He has done this in the past just a few times, but it seems more often now. I adopted him about 6 weeks ago.

This could be due to the change in the food or the walks or something unrelated. I would offer him just a small amount of plain boiled boneless, skinless chicken and white rice to see if this helps to settle his tummy. I would try not to walk him immediately after feeding him. You can walk beforehand or wait about 30-45 minutes afterwards. If this helps, then I would slowly start to mix in his new food with the chicken and rice for a few days until you have him transitioned over to the new food. If he is continuing to vomit, becomes lethargic, starts having diarrhea or anything else abnormal, I would have your vet take a look at him. I hope this helps and he starts to feel better soon.
