It has been my experience with the two collies I adopted and the 2 adopted Pyrs that once you get them on a high quality food, the coat blossoms. I used to feed Innova, and it really helped the coat of the Blue Doberman I adopted, and the Red Doberwoman I adopted is now 14 years and 4 months old. She is still going strong, and "rules" the two Pyrs. I do believe it's all in the food. Colleen's (3.5 YO) coat is so thick with undercoat that you can barely dig your fingers down to the skin on her rump, and Bone is the same way. He is almost 3, and has had a total change since I adopted him in November of '08. I would really like to know what the best brushes are, and grooming tips for these walking hairballs! With regard to spot-on flea meds, many of them have an oily base, so that could be why the skin seems oily down the middle of the back.
