| I know fleas can cause patchy hair loss, and also food allergies. My pitbull was loosing hair in big patches all over, and I originally thought it was hot spots, but after going to the vet she told me that it looked more like a food allergy and to try a different food protein such as venison, or duck, since those aren't so common, and usually only used in hypoallergenic food. I would try mixing some hypoallergenic food in with his normal food, and then switching all together for a month and see if that helps. I use Natural Balance Duck and Potato. The vet told me when switching the diet you need to switch it completely, that means buying the same formula treats, and only allowing him to eat Duck and Potato treats, and Duck and Potato food. Just a thought... |
