Joe, they are just fastened around the abdomen, covering the penis, to absorb any marking or urine that the male dog may discharge. Many of them are sewn in with a flannel lining for softness (and less matting on the coat), and the majority of people I know use a feminine pad inside in case there is a need for extra absorbency. (A feminine pad also reduces the need to rewash the belly band as often.)
I know one breeder that just goes out and buys mens tube socks and fastens them with a safety pin. Easy peasy.
