Lilly does the same thing, but only occasionally now. Her vet told me to turn feeding time into a game and have her "hunt" for her food. We stash a bit here and there throughout the house and tell her to get it. I have her scent some of the food that I have stashed in my hand and she goes to work. She loves the game (almost like hide and seek), she gets a full meal that isn't inhaled so fast that she ends up hurling, and it reinforces the new skill I'm teaching her (scenting and tracking).
I also recommend to clients who have dogs that inhale their food that way to put obstacles in the bowls or feed on a cookie sheet. I tried to feed Lilly on a cookie sheet, but she pushed the food into a lump with her nose and inhaled it anyways. So....A hunting we will go...A hunting we will go...LA LA LALALALA...A hunting we will go....
Lol!
