x11, this is really, really bazaar behavior. My initial post may have been a bit premature. "The mother dropped the pups all over the kennel and cowered in the corner of the kennel geting as far away as possible snarling and bristles up."
My picture is a kennel maybe 10' x 20' give or take, where the bitch is in there literally whelping (dropping) puppies all over the place. It sounds like she she totally freaked out. And was delivering the puppies in a kennel environment where there may be other dogs in other runs increasing her stress.
Whelping is terribly stressful on a bitch. I have been blessed with good dams, who care about every single puppy born. My very first thought was a c-section. Some bitches when they have a c-section do not realize these are her puppies, and the anesthetic wearing off is disorienting, and suddenly finding herself with a bunch of hairy little monsters might have been rather hairy. But then I saw dropping them all over the place -- I guess I am just thinking that we are a lot more hands on when it comes to whelping litters. We do not let them drop them all over the place. We have a 4 foot square box, or a 4'x5' box, and we are right there. It is very hands on. But the emphasis is always not to stress the bitch, any more than she already is.
I usually pull the puppies out and put them in a box, either right in or right out of the 4' box, when she starts turning to have another puppy. It is a terribly wet and messy ordeal, and puppies must be kept dry and warm, so I put them in a box when she is turning and spewing water. But if she stops and starts paying attention to where that pup is, I just put it right back in with her. I will dry it off again when she is working on the next one. Keep stress levels down.
The idea of the dog doing this in the ordinary kennel run where the other dogs are running back and forth in their runs barking and being idiots -- they do when people are there and when stuff like this is going on, made me cringe.
But it can be worse than that, If she had her group of puppies and all of sudden started scattering them, and cowering in a corner growling and bristling and then killed a couple of them, I would be worried that something was seriously wrong with her, was this right after whelping them, or was this a day or two later. Could she have a serious infection. Bitches can kill their young if they feel seriously threatened, and having a stuck puppy or a retained puppy that is sickening her might cause this.
I guess we just don't have enough information.
It is common for people to suggest that a bitch not be left unattended with her pups until the umbilical cords drop off (a few days). Usually I stay right with a new mother as I cannot know that she is an excellent dam unless I go through a few days. But I have to sleep too, so I stay close and I do sleep if all is going well with her.
As for breeding this bitch again, my gut reaction is no. Even when I have a bitch develop a bit of a fever, I haven't had them attack and kill puppies. Again if it was a C-section, that could be a whole other story though. If she was terribly young, like 10-15 months old, maybe that played a part in it. But even puppies that have puppies usually do not act this extreme. If it wasn't a c-section, then I would say she has some wires crossed in her head.
The sire of the litter is of no consequence in this, and I am not sure why he is being mentioned at all.
