A bit of anecdata - but all of our animals (few dogs, couple cats) have shed significantly less and had a much healthier looking coat once we switched them to better foods.

The reduction in shedding going from kibble that's primarily rice and corn to something that's actually nutritionally appropriate ingredients for a dog/cat was astounding (but should have been unsurprising).

My understanding is that pet allergies are generally allergies to the shed hair and skin, so a healthier diet may have reduced that significantly.
