Kathie, When I do back-to-back breedings the time I wait is until the next heat cycle - this can be anywhere from six months (from the start of the previous heat cycle - which produces puppies six months from birthdate of previous litter - plus or minus) up to nine months, or more, if that is how long it takes the bitch to come into season again. They all differ! As it takes the uterus 4.5 months (about 135 days) to recover from the last cycle, I won't breed a bitch who cycles back as soon as this 4+ months as they won't carry a litter on this next cycle. Oh, they'll happily play hide the salami, but they won't get pups :-)
