If you apply Aloe to a dog's skin..it helps soothe the irritation. I went thru this with my siberian husky...and its EXHAUSTING trying to find out whats wrong. The doctors never figured it out...but i noticed he did well when i gave him benedryl everyday. I thought it was environmental cause it only happened during certain months. We went thru all the thyroid testing ...it wasnt that. I wish you good luck cause i know what you're going thru...its awful.
