Barney is a Catahoula Leopard dog that we rescued at the age of two. He'd been in and out of foster care most of his life. He was so mellow and sweet, we thought he was the perfect dog! But he was just too mellow and too quiet, so after several trips to the vet and my persistence we finally got a diagnosis of Canine Ehrlichiosis, Brown Dog Tick Disease. He wasn't mellow; he was dying! He's still on medication and may be for life, but he now digs up the yard (his nose is constantly dirty) and plays fetch until I drop. And he eats as if he's part pig. That tail of his that never used to wag is now a weapon. It's more of a whip than a tail! My luckiest day ever was the day we found Barney. God bless the rescue groups that take care of these dogs until we find them.
