[Chico's Mama]

I think my Chi does the same thing yours is doing, but he only does it when he gets excited, like when someone walks in the front door. The vet said it was reverse sneezing and I should give him childrens benadryl (sp?) You said yours does it when you pull on their collar on walks? I wouldn't pull at all because their trachea is very sensitive and pulling to hard could cause it to collapse...I'd switch to a harness if I were you.
