My dog eats grass and throws up yellow foam. Is this normal?

Updated on September 23rd, 2025

My dog keeps eating grass. Now sometimes he'll puke it up with a yellow foam. Should I be worried?

Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach!

Dogs may vomit after eating grass. No one exactly knows the reason why dogs eat grass, but I would try to prevent him from eating it as best as you can. I would say if you prevent Freckles from eating grass and he still is vomiting, then I would recommend Freckles see his veterinarian for an evaluation and exam.

I hope this helps!
