I'm glad they found a reason for the vomiting. It is really worrisome to see them doing that and not have a reason for it.

I never feed my dogs rawhide. I saw a little pup about 4 months old get a soft soggy part stuck in it's throat and almost die. Someone actually did the heimlick on him and he was ok but it was close.

I give mine the super hard nylabones. They are agressive chewers and these things last a long time. It helps keep their teeth white too!
