I'm so glad to hear Rebel's test results didn't show anything too alarming. Hopefully the antibiotics will do the trick and he'll be back to normal in no time. I wouldn't worry too much about one vomited meal if he kept something else down later. And of course I know you'll keep a close eye on him until you're sure he's 100% again.

And hooray for you for feeding a homemade diet. Most vets may not approve, but what most vets don't know about nutrition really can be alarming. Your dogs are very fortunate to have such a loving, knowledgeable, and dedicated owner.
