My dog keeps vomiting foamy liquid and hard chunks, what should I do?

Updated On September 23rd, 2025

Pet's info: Dog | Black Mouth Cur | Male | unneutered | 75 lbs

I'm dogsitting and one of the dogs keeps vomiting. It is granular and there are very few chunks in it. The first few times it was solid and brown, like diarrhea except I watched him throw it up. The past 5 times its been watery and foamy, his stomach is emptying. The chunks in his vomit are the same color as his dog food, but harder. Like a stress ball. There are also some pieces that look like fat worms but when touched they look like fatty tissue.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If Odin vomited up foreign material and is continuing to vomit, I would strongly suggest getting him in to be seen by a veterinarian sooner rather than later. If there is something causing an obstruction somewhere, this can lead to further serious problems that can be life threatening if not addressed right away. I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
