Puzzle is 16 years old, has sweet itch and is semi retired due to a mouth tumor being diagnosed 2 years ago. After being given only weeks to live he's still here and fat! I contacted the Simple System helpline after Puzzle became increasingly itchy. I now feed Puzzle on Ruff Stuff, Lucie Pellets, Total Eclipse and Instant Linseed. He gets all he needs in a small feed and his skin is lovely and supple and has not dried out this year when he has rubbed. He's loosing his weight steadily without comprimising his nutrition and looks fantastic!
