gagging

Question
my english bulldog threw up and now is gagging he is 11 weeks old

Answer
I don't know if Bulldogs are as bad about gulping things down as Labs or not.  If he doesn't settle down you may have to contact a vet yet tonight.  If you don't have an emergency number, try your vet's regular number.  Otherwise try to find an emergency service.  

if he settles down, keep an eye on him.  Any diarrhea or more vomiting, and call the vet.  

Sometimes they clear out what is causing the problem, and they are fine.  Sometimes it takes surgery.
