I have a black lab with flaky skin most of the year. She scratches as well, but it's not fleas. Once or twice a year she does have to get a shot and allergy medicine since her skin flares up. I currently feed her Nutro's Senior dry food and supplement her food with Derm Caps ES and 2000mcg of Biotin. Do you have any recommendations for other supplements/food or to increase her current supplements? Please let me know. She's also bathed once a month wiht coal tar or oatmeal shampoo.
To tell you the truth, I can not think of anything else to give her. I quess you can try a moisturizing spray such as Hydrapearls. It sounds like you are doing a good job. Vetcare
