Bulldogs World

iesel when i got him as a rescue had a beautiful coat. then slowly as the past year has progressed he is loosing his hair. Some people said it may have been SFA the vet even did special lab work and said his thyroid was a little low. They put diesel on thyrexine i think thats what it is called. he has been on it for a month and it has actually accelerated his hair loss. The symptoms are loosing hair on both sides of his body, the skin underneath is very dark grey to black. it doesnt seem to itch it is just falling out and not growing back. i was thinking stress but the dog has the lap of luxury eats sleeps and farts, gets up only to use the bathroom or chase the ball, or to bring me a big sloppy slimey tug rope that he loves. i need to find a good bulldog vet in the hampton rds area of virginia and have him looked at. it just makes no since to me why he would keep loosing hair.  thanx anyone for any help

SFA? not sure vet i go to doesnt seem to think so?  

what else should i try? just bothers me my little guy is loosing his hair. its not MANGE. nor Ring worm
