I have a dog who is constantly licking his paws. I heard that this might be caused by a food allergy. What in dog food would most likely cause this? What is the best kind of food that I should give him instead?
The best food is one that he is not allergic to.
I don’t mean to sound silly, but an allergy could be caused by ANYTHING. The fact that he is licking his paws indicates to me that it is more likely to be a contact allergy, i.e. something he walks on.
See a vet.
