My dog ate fast food, is vomiting, and won't eat. What to do?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 3 months and 21 days old | 8 lbs

My dog got into my lunch on Thursday it was DAIRY Queen. He had some of the fries, burger and part of Sunday. He threw it up. Then Friday he has a partial wet partial normal feces. He drinks water for me. But he won't eat . He ate a bit of dog food yesterday but threw up bile bc his stomach was mostly empty last night. I'm trying to get him to eat a bit of chicken rice or potatoes but I think he's not eating bc he doesn't want to throw up. Is there anything more I can do at home?

Rockie is adorable and I'm sorry to hear that he isn't feeling well. After eating a heavy, greasy meal, he may have developed gastroenteritis (inflammation in his stomach and intestines) or pancreatitis. Aside from assuring that he is drinking water and offering a bit of a bland diet (boiled white meat chicken and rice) as you have done, there isn't anything more that can be done at home. Young puppies are more susceptible to the effects of dehydration than adult dogs and need to be treated a bit more urgently. At this point, Rockie needs to take a trip to the vet for an exam, diagnostic testing and supportive care (IV fluids and medications). I hope that he is feeling better soon!

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor guys!

    It is possible that all your dogs are sharing a viral or bacterial infection, or a parasitic infection or even all are eating something that is causing an upset stomach. I would with hold water for 6 hours and if in 6 hours there is no vomiting then offer small amounts of shallow water frequently. Do no offer food for 12-24 hours. As long as there is no vomiting during the fasting period start them on a bland diet of boiled chicken or hamburger with rice. Feed 1 cup per 20 lbs per day as small frequent meals until 2 normal stools. If any of the dogs continue to vomit while being fasted, won't eat or vomit once they are fed then they should see a Vet on emergency if yours is not open.

    I hope this helps!
