No hind shoes?

[Cannon Shell]

Old timers like Frank Whitely never put hind shoes on a horse till the day of their first race. Of course he really didnt know what he was doing as he was just hopping horses with cocaine according to Jim Squires.

OK, so if I had to form a consensus from the comments here, I'd guess that "no hind shoes" is not something I should throw a horse out for, that it is not that uncommon of a practice, and that there are no regulations that require a horse to run with all four shoes on?

Thanks to all who tried to clear this up...
