Question...has the vet diagnosed it as allergies and to what substance? Allergies can be from food, pollen, and lots of things.

At one time we thought Dusty might have had a food allergy and tried IVD duck and peas, but it can only be purchased through a vet. Turned out she wasn't allergic to her food, but it was worth a try. She just turned 16 last month, and we've come to the conclusion she's obsessive compulsive or slightly senile.

Good Luck
