Jennifer yes, my vet said he sees more white dogs with skin problems then brindle, black, tan dogs…. My next dog will not have a bit of white on him……
Have you ever thought of doing the Salvia & Hair testing thru “Glacier Peak Holistics” it cost $85 & they test for 100+ Environment triggers & 200+ food items, you may be surprised with what he’s sensitive too.. I know vets say you can get false positives with blood testing but everyone I know that has done the Glacier Peaks test were pretty happy with the results & it was pretty accurate with foods that people knew their dogs were sensitive too & cheaper then a Dermatologist & you may find out what is causing the itch….
