Maybe it is still the food? My vet never said it was a allergie. He bascially just said she is getting irritated by something..>>>>>>>>

Gosh! allergy signs our pretty vast, such as licking, scratching,
snorkling-breathing,sneezing,eyes,skin,coat and spitting up.
Two of my dogs suffer, which I Believe is allergy because
it seems to be seasonal. My Rocky is the worst, it can be air borne and also something he eats outside that upsets him.

If you do decide to question
your vet about Presley getting allergy tested,
I am curious what your vet says.
