My pit bull is severely allergic to grass, black ants, pollen, ceder, trees, fleas, etc. Basically she can't go outside without being sick. We love her like our child, and we hate to see her this way. She is always irritated. We give her benedryl, like the doctor perscribes, and she gets a shot every other day. Still for over a month, neither of these things work. We give her baths with special cortizone shampoo and still she's bothered. Her ears are horrible, we clean them daily. What else can we do? Any suggestions? She's so beautiful, we just hate the hives!
