I was hoping to find out the age of the dog so I could shed further light. While I have not had a pregnant LGD eat a lamb I have one female, that when pastured with her pups, killed several lambs (always the runtiest) to feed her pups. In each situation the sheep had devoured the dog food set out for the puppies that night and she understandably felt a need to feed them! In each instance she actually did not partake in eating the lamb herself, just sat back and let the puppies eat. She also spent one morning scrounging through a road killed deer to proudly retrieve the liver for her 5 week old pups. I have heard of other instances where pregnant or lactating females killed lambs but in all instances the dog owner admitted a lack of management/feeding of the dog at the time. So I guess I would agree that the survival instinct in these dogs is there and they will provide for themselves if they feel their needs are not met.
Stan touches on something we have experienced with pregnant bitches which is the need for additional, higher quality food during the last few weeks of pregnancy. These dogs have exceptionally large litters, and if you look at what they are producing on a per pound of body weight basis are putting out an impressive level of production compared to our other farm animals. Normally dog breeders feed the bitch puppy chow, but I've noted a problem whereby our dogs cut back on dog kibble in late pregnancy ...just when they need to be eating more.
After loosing one bitch to what I think was probably a metabolic crisis brought on by her refusal to eat dog chow during the last two weeks of pregnancy, I filled the void with ground burger (ground mutton). Mark L. pointed out the need to add calcium to meat, so I now add a powdered calcium supplement to the burger. The burger is consumed very well and I think it pulled Mocha through her pregnancy this spring.
There are other aspects of LGD nutrition that I think are not met by dog kibble alone. For instance in the winter I have observed LGDs consuming wool off of fences, and some dogs might even take to plucking wool off of sheep. The addition of the occaisional deer hide, which is consumed, hair and all, seems to temper this. I have wondered if the snow pack and lack of access to vegetation leaves the dogs lacking for fiber in the diet?
one last comment about timing of pregnancy and lambing. I do pass on a heat cycle if the intended litter is going to be born at a bad time. Bad timing would be any time the temperature is below +20 degrees F, or during or right after lambing, and to some extent I pass on fall litters as well (pups do not move in the winter as well as they do in the summer). the ideal time to have LGD pups is about a month before lambing. The new pups will have some size appropriate lambs to begin early socialization with, and will be young enough to be safe to put with ewes and lambs that first summer, and the bitch will be ready to go back to work when the new lambs arrive.
