I use Mavic Askium’s Not to heavy not to light.Their probably one of the most popular cx wheelsets with normal club riders.
Merlins got a good deal on them.

Realy!!!!!!!!!! Just tell him to get the GT from Paul’s.

I tore mine andmy Jack Russell tore his.For what its worth it seemed to bother me more than it did him.The smaller the dog the better and the more chance he’ll make a full recovery without surgery (i didn’t,he did).Oscar was on pain killers for a week and used to lift his bad leg up a fair bit,but made a full recovery after a couple of months.
