Are you the trainer of this dog? Is this your first time as a trainer? Wrist injuries can be repaired easily, it doesn't mean the end of the dog's career.

The dog is only young, its bones are still forming so it is probably due to constantly trialling that has caused some kind of wrist injury. A short spell and treatment should see him come good, unless of course you mean he has shattered/broken his wrist so badly he is useless for racing.

Also, no one will breed with a dog that has not shown any form, being a pretty face is not enough to make it worth the while to breed. Especially since we don't even know who the dam is!
