Why is my dog throwing up yellow foam after eating once a day?

Updated On September 23rd, 2025

Pet's info: Dog | Beagle | Male | unneutered | 2 years and 10 months old | 46 lbs

Hi There, I have a dog. Beagle. 3Yrs. Male. He is threw up today morning, some yellowish liquid with foam. Is this bile flux..? He did this 2-3 days back as well. Does this mean stomach infection..? Or is it due to his feeding habits. He usually late once a day, but since the last occurrence 2-3 days back I am trying to change his habit and make him eat atleast twice a day. He does not look sick. His stool looks. Any suggestions???

This could be simply acid reflux since he only eats once a day. Some dogs will vomit bile when they don't eat often enough because the acid will build up in their stomachs. I would feed 2 times per day to see if this helps. If he is still vomiting bile, I would have your vet take a look at him to ensure nothing more serious is going on. Your vet could also tell you a antacid brand and dose that would be safe for him depending on his medical history. I hope this helps!
