The last month or so, Lola has been making choking sounds and/or gagging and throwing up occasionally. We tried a new food about a month ago (Fromm Gold), and after 3 days of throwing it up, went back to her old food (Fromm Surf and Turf). The only reason we tried to switch was because her tear stains came back. They are now gone again. Any idea what could be causing the gagging and choking? When I say choking, it's not like her airway is blocked or anything, it's just a hacking sound. Our vet did tell us she has an elongated palate and recommended surgery. I wanted to wait a bit to do that, and maybe get a second opinion. Could the palate cause the choking? I kind of thought it just caused breathing issues, but don't really know.
