My dog scratches almost constantly and bites at one spot on his leg to the point it's discolored. He does NOT have fleas. Could this be a food allergy? If so, what food would you recommend?

It is unusual for a food allergy to only affect one area and there may be an underlying trigger or painful focus in the area which should be excluded by your vet, compulsive behaviors can also develop but would improve with an e collar and changes in routine such as additional walks, activities and chew toys to distract him. Food sensitivities are best ruled out by a 6week food trial on a hydrolyzed diet such as royal canin hypoallergenic, symptoms would then recur if you rechallenge with the original foods
