I usually give mine a nice trim with a belly shave .
I also do a belly shave and keep the very long hair divided as "mini " pony tails, but i preffer a cut like a puppy cut. Females when they whelp and nurse, they loose some hair anyways , the belly hair falls off , and the body hair may thin out ... so mother nature takes care of nipples being free for the puppies to find anyways.
