The Chosen Few shaved his dog, Tito Trinidad when he faced Ch Vengence (and he also came in a pound heavy).

It did not help TCF achieve his desired end, either in having a shaved dog, or in bringing the 2-lb bigger dog, to win the fight.

IMO, shaving dogs is one of those things "some people do" that has no bearing on anything.

In the end, some people do things that are effective; some things people do things that are a detriment; and some people do things which are ultimately ignorant superstitions that don't actually do a thing.

At best, shaving dogs would be categorized as the latter.
