I've read and seen all kinds of remedies for hot spots but what are they exactly??? Every summer-only during the hot weather months Sophie loses the fur around her tail, not large spots, nickel sized actually. Then she itches by biting herself or scratching up against chairs. I've been using oatmeal spray from Petco and a bit of neosporin. It isn't bugs, I checked every inch of her for fleas and nothing. I haven't changed her food or any products in the house or I'd think allergies. But it doesn't happen in the fall or winter, just the same time every year May-September. Any suggestions?
