My dogs are on Innova too and I think it does a very good job of keeping their skin and coats in good shape. But, when Raemi had her TPLOs and had so much hair shaved off, I started adding salmon oil to her diet. Anesthesia alone tends to do a number on hair and with the incision, shaved areas and general all-over healing I figured she could use all the help she could get. I have been so happy with the results that I started giving it to Breccan as well. It just seems to add that little extra softness and shine. People always remark on how clean and nice their coats look and feel. It does seem to me that dust and dirt don't seem to 'stick(?)' as easily to them as before either. I do insist on pure salmon oil, mercury free and from "deep cold water fish". Both dogs weigh about 160 and get (2) 2000mg gel caps a day. JMO
