Why is my dog throwing up yellow bubbly mucus and not eating?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 2 years and 4 months old | 18 lbs

I'm a little concern about my buddy. Today he threw up, no food, no unknown things in the vomit only bubbly mucus and yellow. He had not eaten breakfast yet, he pooped normally. He had blood work done on April 11 and all was fine, he actually is a healthy pup, but he had vomitted after the April 11 visit, not everyday or weekly, but it had occurred and again a phlegmy and yellowish jello type substance. When that has happened he seems down and doesn't eat until hours later he becomes himself...

I would be concerned about Buddy as well. It could be he has a GI illness. I will give you a home remedy to see if that helps. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. Best of luck.

    She might have eaten something spoiled that is causing this. withhold food for 12 hours then offer Chloe boiled boneless chicken and rice every 6 hours in small portions. if she is eating and not vomiting, continue with this diet for 2 days. After 2 days, you can put her back gradually on her normal food. If she continues vomiting or is not eating, take her to the vet to get treatment.

    Thank you for submitting your question regarding Stella. If she is otherwise healthy and she is still eating and drinking normally, then it should be fine to monitor her. However, if she is not eating, continues to vomit or is acting lethargic, then she needs to see her veterinarian. There are numerous causes of vomiting and she will likely require treatment. I hope this information helps!
