Just curious, what test indicated she had all these “food allergies”?
Oh, and food sensitivities fluctuate.
Has the dog had a senior workup? There very well could be other reasons for symptoms (although you never described any) have you ruled out medical, via lab work and a good physical exam by a veterinarian?
“Food Allergies are probably over-diagnosed in dogs (they account for, perhaps 5-10%). Hypoallergenic diets are occasionally, but not frequently, helpful in canine atopy cases but you should always give them a try. Food intolerances are more common – but considerably more likely to result in digestive disturbances and diarrhea that in itching problems”.
