We bought a large herd of goats last year along with four Great Pyrenees dogs, who stay with the goats and protect them from predation (they did an excellent job this year, we didn't lose a single goat to predation out of 300+, most of which were babies!). But anyway, we bought four Pyrenees females. One we bought as a spayed adult ("Karma"), another we bought as a three year old, not spayed ("Nommi"), and we also bought two sister puppies, not spayed ("Heidi" and "Sheba"). When Sheba and Heidi got to be about 10 months old they both went into heat. The neighbor's dogs would come over here, Heidi and Sheba would go over there, there was no keeping them separate. Nommi would not allow the neighbor's dogs to breed her, however she was fine with them being in the herd, so long as they left her precious goats alone. Two months later Sheba had five mongrel puppies. Heidi did not. Earlier this year the same thing happened. Sheba and Heidi were in heat, Nommi still would have nothing to do with the neighbor's dogs, and two months later Sheba has a litter of eight puppies. Heidi again has no puppies. So we decide that Heidi must be sterile, which is a shame because we had plans of eventually getting a male and breeding the females so that we can sell small herds of goats, complete with a dog or two. Heidi was certainly being quite the naughty little slut, very flirtatious if you know what I mean. But we never actually saw her being bred. But anyway, this summer we finally found a mature intact Pyrenees male. Heidi and Nommi both went into heat in October (Sheba was still recovering from her last litter). They went into heat a week apart, so "Big Guy" (he came with that name) was able to stick like glue to each of the girls for a few days, keeping the neighbor's dogs well away from "his girl." I saw him breed Heidi October 30th. She seemed in pain. She was whining and yelping and trying to pull away, but couldn't. A week ago we started noticing that she was getting quite thick in her mid-section, and her teats were developing. So we're very thrilled!!!! Our first purebred litter!!! But my question is.... Could it be that "Heidi the slut" was holding out for a livestock guardian male, like a good female livestock guardian dog should? Is what I witnessed evidence for the fact that she had never been bred before? That she was a virgin? Or no??? Please try to keep your response as family-friendly as possible, or PM me. Thanks!
