Why is my dog vomiting white foam and distressed after eating?

Updated On September 23rd, 2025

Pet's info: Dog | Rottweiler | Female | spayed | 6 years and 2 months old | 105 lbs

My Rottweiler is vomiting up white foamy vomit. She has been doing this for a couple of Days and I called the vet clinic. Gave her a Pepcid 20 mg. She seems to be in some distress after eating each time. Got into some chicken dressing that I had thrown out for the birds and it could have had onion or garlic in it. I didn't feed her anything foe 24 hours and now just small amounts of ID prescription as she does seem to have a sensitive stomach. She has been on ID for quite some time.

Hi there. If she seems to be doing better now and the vomiting has resolved, it should be fine to continue with the current plan of giving her small amounts of i/d for the next 2-3 days before gradually switching back to her regular diet. If she's still vomiting despite the Pepcid and bland diet, then I would say she definitely needs a vet visit at this point to determine what is causing her symptoms. She may have an intestinal obstruction, pancreatitis, or some type of systemic illness like liver or kidney disease. Your veterinarian can do blood work and x-rays if needed to help diagnose the problem and get her started on appropriate treatment depending on what is found.
