Npw that you mention the Woobie eats K/D(canned???), our Tina Peepers, who was eating Royal Canin canned Duck for allergies, was put on the canned K/D when her labs came back indicating early kidney disease. THEN I noticed that Tina was pulling out her fur(which had grown back nicely while she was on the Royal Canin Duck). I decided that at 12 and a half years, I want her to be comfortable and not itching to death, so despite the little higher protein in the RC duck, I switched her from the K/D to the RC duck. She is considerably LESS itchy and her fur is growing back. My vet agreed with the switch. Maybe your Woobie is allergic to the K/D....please let us know what happens at the vet!!! Sorry I was so wordy...
