My jack russel/westie has severe food allergies. He lost most of his hair on his belly and limbs and would often have on and off ear infections with a foul odor in both ears and black spots on his belly too. I’m using this, along with a homemade/ raw food diet, and organic and natural balm to help with his dry skin/itchiness and also children’s Benadryl and flea collars. I started all of these around the same time so i couldn’t quiet say for sure if it was this that has helped but I definitely think this product is a good addition to his new diet/lifestyle. His hair is growing just after a few days of using this and seems to really enjoy the flavor.
