Like Jeannie says - get him out doing something fun and he'll forget he has them on!
For competition, I use neoprene carpal supports. They are just neoprene with elastic/velcro that I make myself.
I also sell BOT and while they may give a little support, they aren't made for competition and I think they'd wear out pretty quick. My dog wears his BOT wrist supports before and after runs sometimes, but I always switch to the neoprene ones for higher support on the ground speed courses.
The comment about "excessive" made me smile. I made carpal supports with turquoise bling for my boy and I guess some could say it's excessive, but most people like the sparkle.
