Back to Back Breeding & the evidence supporting it:
Reproductive Veterinary Recommendations
Most, if not all, reproductive veterinary specialists now recommend doing back to back breeding as long as the mama recovered quickly and easily from the previous litter. Then they recommend retiring/spaying a dog early.
A dog goes through the exact same hormonal changes and their uterus wears out with every cycle. It doesn’t matter whether you breed her or not. This is why many dogs experience what is commonly called false pregnancies. Older un-spayed dogs become more and more at risk for a common but dangerous infection of the uterus call Pyometra the more heats they have, whether bred or not.
Rockpoint's Philosophy
Our philosophy is to breed each of our girls once they are of breeding age every season with a few exceptions. I won’t breed a momma who isn’t in excellent health. My goal is to breed my girls every cycle once they are old enough (appr. 2 years of age) and then to retire them early, this typically happens after 3-5 litters. 5 litters is the max recommended number of litters.
This was not a decision made lightly, but after much consideration and research. Other experienced breeders across the country have reproductive vets saying the same thing. Breeding back to back and breeding dogs young is what is best for the dogs.
