don't know what to think...my bernese mtn dog is having some sort of strange fit where he keeps swallowing a lot, tries to eat grass and is scared. i don't think it's bloat b/c i can touch/gentle push/squeeze his stomach area and it is not painful at all to him. is this what a reverse sneeze can be like in a big dog? he sometimes gets a weird cough sound (not like a honking goose).....is this some weird form of the backwards sneeze?? pleaes advise, someone!
