I SWEAR by ground flax! It always makes him look so shiny! I buy it at the local health food store ($0.79 a pound) and I usually buy it 5 pounds at a time, grind as needed, and feed it to the horses. They ALL get it, but it really makes him nice and dark and shiny! Isn't he a sexy boy? (Sorry, girls....he's GELDED!) (tee hee!)
He can be a BRAT though! Right now he's going through his "Uh, uh. I DON'T want to be haltered!" stage. First it was the "I don't want to go through gates" stage...now the halter stage. I need to work him through this.
