Two of the Three Casa de Kolchak dogs love apples as a treat. (The third dog does this when you try to give him one. Go watch. It’s ridiculous.) Even fussy Kolchak loves it when I make an apple dog treat recipe. Apples are a good source of fiber, Vitamin and Vitamin C, but they might not be the best choice for dogs with itchy skin. (Apples contain natural yeast which can aggravate the itchies.) Always make sure you peel the skin (or thoroughly wash off any wax & chemicals using a white vinegar wash) and remove all the seeds before you share apples with your dogs.
