Foamy Vomit

[Dave]

There have been a couple times that Benny has thrown up, not food or chunks of things he's eaten, but yellow foam. I was wondering if anyone knows what this is or why this might happen? I've heard that dogs do this when their stomachs are empty. But if there's nothing in his stomach to throw up, then why does he do it?

It's bile. Tucker sometimes does it if he eats fuzz or hair and he has to throw up but he hasn't eaten any thing. Cockapoos tend to throw up when they eat something abnormal like fuzz or hair or something from outside. Tucker does it occasionally. The vet said it's normal when they eat something abnormal.

We had a whole ordeal with Tucker where he was throwing up constantly and he had to stay at the vet and it turned out ha had an irratated esophagus from eating something.

Ah thanks for the insight. :)
