Why Is My Dog Throwing Up Yellow Bile?

My dogs do that if they eat their own feces or if they eat house food that doesn't agree with their stomach. I would suggest that you clean it up before they re eat it and crate your dog for a  hour or so until they calm down so they cant run around. My vet told me last time to give my dog a half of a tums chewable tablet and my puppy magically stopped puking. Or it could be parvo. Call a vet.

My dog threw up yellow bile he didn't eat anything funny?

She may be pregnant or she may have eaten something that did not agree with her if it cures for a couple of days you need to take her to the vet?

It may just be upset stomach

My labradoodle vomits yellow bile if he hasn't eaten for 14 hours or so. He is a fussy eater and sometimes turns his nose up at his usual food and sometimes eats it OK so he is quite hard to feed regularly. I have found though that if he has at least a couple of bonio biscuits he doesnt vomit.

It also may be fleas,for dogs when infested may lose their appetite and vomiting ,also fever.
