From what I have learned racing Greyhounds spend almost all of their time in a crate. Let out to go to the bathroom and when it is time to race. I suppose that it is a big business for some. If the dog races well he/she will go onto race for up to 5 years. Blaze's last race from what I can find was last May 14, 2008 but sometimes races don't get updated.

You would think that the breed would be angry after all of that. It is completely the opposite. He is so timid and kind. He went from 40 mph to couch potato in no time

When I take him to our large back yard he reminds me of a track star. He first stretches the front legs then the back. Begins to jog then lets it go full throttle with a bust of speed.
Were taking him in tomorrow to meet our vet and get a wellness exam. He did have all of his shots and teeth cleaned just before we got him from the adoption agency. The Greyhound adoption people are really amazing. My hat goes off to all of those volunteers that help get these great dogs placed with families.
