Welcome to FBN! I have fed our dogs raw ever since we had a senior English bulldog with allergies. They basically get various raw meats and organ meats instead of kibble (I'd be happy to give you more info if you are interested). The big draw for me was that it helped with the allergies plus the skin and coat looked great (and waaay less poo to deal with, their body uses up most everything and the poo that they do leave just turns to dust)

Aveeno oatmeal packets( generic works the same) is very soothing, especially in the winter.
Allergy testing - done with a blood sample or like human allergy testing (with all of the stick spots?). My ex, who is a vet, says he is having luck w/ the blood testing.
