Hi
I do have a brother and sister littermates. Yes it has worked but I wouldn't do it again. What I would strongly advice against is having the male neutered "as early as possible" -if I had my choice over again I would rather arrange for somebody to look after the bitch when in season the first time or two, or vice versa. I spent a lot of time socialising both pups separately -they went for separate walks, went to training classes separately etc, but even so the bitch cannot cope without the dog. The dog is okay away from her. But my main problem is that as they (both) were neutered early (5 months) both are still like puppies at the stage where they spook easily (they are 3) and have never gained any confidence. Essentially in the case of the dog, I have a 27" 45 kg huge dog who is terrified of his own shadow almost. If he sees a small dog, he will run! He has no confidence at all, and I believe this is something that can happen when neutering early. The bitch is actually even WORSE, she's even timid with *us*, yet NOTHING bad has ever happened to either of these two. I do notice a BIG difference between mine and the puppies in the same litter that went to other homes singly and were neutered later. The others are a lot more confident.
So personally I'd advice neutering once the boy is mature, and make arrangements for the meantime. Hopefully you will then avoid my problems. Don't get me wrong, I adore both mine and neither are a problem as such, wellbehaved etc, but I feel awful about how timid they are. I think the double whammy was the catalyst here -littermates AND early neutering . I did of course have my reasons at the time for the neutering, now I wish I could turn time back. (Like you I hadn't planned to keep two pups, it was just necessity after the home for the bitch fell through.)
