After a really bad year for poor Molly, coat and ear wise (She had to have surgery to drain a hematoma, and to prevent a new one), she looked BAD. Her ears were half bare, as were her eyerims, and she had baldish patches on her side with shiny blackish skin under it. She was scratching like hell, and I had tried everything else I could think of, different foods, supplements, etc. I found an article about Canine zinc-responsive dermatosis online: Canine zinc-responsive dermatosis - DVM The patches on the dog in the pics and Molly were almost identical, so I ended up ordering zinc buiscuits: Zinpro Dog Biscuits - 4 lbs At first, the only thing I noticed was her coat really seemed to blow big this spring, there was hair all over, then as the time passed, her coat came back in, and for the first time in at least 5 years, 100% of the hair came back on her ears! The spots around her eyes came back better than I think it ever has, and she has a full, shiny coat, easily the best in her 10 years. Before the biscuits, she scratched all the time, but really bad in the winter, but I haven't seen her do any scratching at all for months now. I gave her 4 of them a day, until I had some money issues and cut her down to one or two, and it seems like that's enough to keep her skin issues in check. I wish I would have tried them a lot sooner. If you have a dog with unsolvable skin issues, and about the only thing they offer at the vet is prednisone, give ZInpro a try!
