My dog bites and scratches one leg spot. Could it be a food allergy?

Updated on September 23rd, 2025

Pet's info: Dog | Carolina Dog | Male | neutered | 55 lbs

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

    Food allergies can cause scratching and itching. A 12week food trial of a hydrolyzed diet or limited ingredient sensitive diet can help to explore the extent of her symptoms that are triggered by food. No treats, snacks or flavoured tablets can be fed during this trial
