I'm not sure if this is any help, but anyway, in my experience, I do not think its a good idea to get two pups from the same litter.
1) its harder to train them in all aspects.
2) they can become so attached to each other, having always been together, it can lead to problems such as separation anxiety.
My personal experience below:
There are two Labradoodles at my puppy class, brother and sister. They are about 4 months old (I think) and have a very strong bond with each other, so much so, when the wife takes the female to one side of the circle (that we all work around) and the husband takes the male tothe other side (or the other way around) they wine like crazy to get to each other. At this early age it looks as if they have the start of separation anxiety. My Puppy class trainer has said that if they, the owners. don't jump on separating the pair of them right now, they'll have major problems soon.
She suggested taking them out for walks separately for at least 50% of their walks, and to also make sure at some point for a while each day that they are not together. Weather it be one goes with the wife/husband to pick the grandkids up from school and one stays with the wife/husband at home, or one goes to visit a friend of the wife/husband and one stays at home with wife/husband. Just so they are apart.
I can see what you mean about keeping each other company. I think dogs need it, so much so, that when out late Westie (RIP my boy) died august 2007, we soon got Marlee our Coker pup in November so our Lhasa/Bichon who was always used to having another dog, had company (even though he wasn't found of him to start with, lol!).
Personally, if I didn't have any dogs, and the circumstances where that I felt my pup needed another dog for copmany, I'd look at getting a pup from another litter. That said, I don't think I personally would have two pups at the same time, because god help me, Marlee is enough! And people on here tell me I've been so lucky and have had it very easy with him.
But yeah, my advice, from experiences, I'd tell anyone that asks for my opinion to, if they really want to get two pup,s think about separate litters.
However, as some have said, sometimes it all goes smoothly and there are no problems, however this I am told is rare!
Please don't take offence, this is just my opinion, and so is not right or wrong, its all down to the individual people and pups. Good luck with your two, and YES Please! Do post photos! All of us on here can't get enough of photos!
