My dog threw up yellow mucus with red spots. Can I feed him?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 3 years and 11 months old | 8 lbs

Last night Chico threw up something yellow and it looked mucusy and it also had spots of red but I'm not sure if it was blood.then this morning he threw up twice more the yellow mucus but this time no spots of red . He did fall off the couch yesterday morning and looked like he was in pain for like 2seconds then continued to run and play could it be from that or is it separate? Should I withhold his food? I already made a apt for Tuesday at 4:15 with the vet.

Hello. Do not withhold food, but offer a very bland diet for the next few days. 25% cooked chicken or hamburger with 75% plain white rice or low fat cottage cheese is usually well tolerated. In a small dig like this, a tablespoon or so every hour or so is fine unless he throws this up, too. If he can keep liquid down, make sure he stays hydrated by using low sodium chicken or beef broth in addition to fresh water. If he throws up the water, offer him liquids in the form of ice cubes ( water & broth ). As long as he seems pretty perky, try managing this until your appointment. If the vomiting is intractable or he develops diarrhea, you may need to have him seen sooner. Thanks for using Petco Pet Education Center, formerly Petcoach.
