My new dog won't eat and is vomiting clear foam after neuter.

Updated On September 23rd, 2025

Pet's info: Dog | American Bulldog | Male | neutered | 40 lbs

New dog. He won’t eat I know he’s stressed!! however he’s throwing up clear foam now due to no eating. He’s still drinking water though. I know he’s in pain as well he just got fixed. So that plus new home and new people I thought it would be expected. But I know he needs to eat and it’s breaking my heart seeing him like this. Please help!!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Baloo! Stress may make a dog not want to eat but stress or not eating doesn't make a dog vomit. Baloo is vomiting because he is sick. If he is on medications after his neuter they could be making him sick and I would call your Vet to discuss stopping them. Causes of vomiting are: intestinal parasites, anesthesia or medications, viral or bacterial infections, foreign body (he ate something that is stuck and requires surgery to remove), food allergy/intolerance, new treats/dog food or human food, toxin ingestion. I would only offer water in small amount and do not offer food for 12 hours. If there is no vomiting in that 12 hour period then start a bland diet of boiled chicken or hamburger with rice. Feed 1 cup per 20 lbs per day for 3-5 days. If he continues to vomit he should be seen by a Vet for an exam, blood work and belly X-rays. I hope this helps and I wish Baloo the best!
