Pooh Bear (boy - age 9) doesn't have his pretty glossy coat anymore. Of course he has lost most of his coloring. His hair along his back is course and scragly and even a bit curly and dry. He sheds a lot too. Anyone else have an older Beagle (no, he's not old, I refuse to admit to that!), anyone have a Beagle with hair like this? Is he missing something in his diet?
