Dog named coltrane sneezing and hurling after eating treats

Spit, you don't tell us much. What kind of dog. How old is the dog? What does the dog eat on a regular basis. Is the dog inside or outside dog. Okay, dogs name is coltrane and is nseezing and vomitting (hurling) after eating treats.

What kind of treats, spit? Store bought treats, or treats you cook up yourself, something other then these two choices??

Tick

Stop giving him the treats and see how he does.

I would have to suggest stop giving him the treats too... Does hurling mean throwing up? Gagging and coughing after eating can indicate other health issues aside from just allergies. Does he do this all the time, or just when you give him these specific treats?
