I have a 10 yo bassett hound with unspecified skin allergies. They seem to be excessively bad this summer. Ske is CONSTANTLY chewing and scratching om herself. I know he must be quite uncomfortable and it’s driving me nuts. She does not have any fleas and does not have flea allergy disease. I have given her benadryl up to 25mg twice a day without results. I am receptive to any and all suggestions (hoome remedies to prescriptions) that may help relieve her of her discomfort.
