my grandpa used to make a leather strap/diaper thing that he would put on his sheep dogs.
It obviously get "dirty" with pee and poop, but it wouldnt hold any like a diaper.
But a male could wear himself out trying but he wasnt going to get none.....
Never heard of anything like that before. Got any pics? Sound like it might get kinda gross but I would laugh my butt off at male trying to figure out why things arent working right.
