I agree with all of thee above but would like to add a lil more spice to this soup. After you've made your decision on whether or not to breed a cold or a hot one, what are ya gonna do with said offspring? If culled correctly u SHOULD get what ur lookin for. I don't mean have a litter of say 6-7 pups and u give away or sell a few. That means let em come up a tad bit, c what they're hittin for then keep what u like. And if ur not doing breedings just for the hell of it, meaning u don't have gangs of litters dropping each year u may even b able to place a few until the verdict is in. When I cull lumber for a job, I don't throw away the ones I don't want bcuz someone could find a use for it. Same principle, try to find a non wrkn home like a friend that always wanted one or local garage that needs a guard dog, etc. Believe me u could save urself A LOT of trouble if u use A LIL of what I said.
