Why does my dog vomit yellow bile in the morning on an empty stomach?

Updated on September 23rd, 2025

Pet's info: Dog | American Pit Bull Terrier | Male | neutered | 1 year and 4 months old | 67 lbs

My dog is about 1 yr 4 months and every month or so (sometimes more frequent + less frequent) since I’ve had him ( October) he has vomited generally in morning. There’s never really any food in it just bile, and he has an appetite. Should I be concerned or is it just cause he hadn’t had food since the evening? He is about 65-70lbs pitbull

This could be due to acid reflux. You can try an ant acid medication such as omeperazole to see if it helps. If you don’t see improvement in 1 to 2 weeks, you should follow up with your veterinarian for diagnostics including bloodwork and X-rays.

    Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. With your description, I would suspect this may be due to the diet. Many cases, about 65-70% of vomiting / diarrhea cases, can be linked directly to the diet or an imbalance of the normal intestinal bacteria. I would recommend switching to a brand new food altogether (Royal Canin, Science Diet, Natural Balance, Purina One). Give the new diet about 4-6 weeks and see if there is an improvement. I would also consider adding a probiotic such as Purina Fortiflora, which can be found online or at your local pet store. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
