If you have not trained a puppy before , it can be a lot of work and might not be advisable. Here's a letter.
On September 13th, 2008 Dr. Jennifer Messer says:
So far as I am aware, there is no solid published data on the issue of problems in rearing littermates. There is, however, a fair amount of anectodal evidence that unless the owner is prepared to spend substantial amounts of time with the pups separately - so they bond more with the owner than with each other - that the puppies are at increased risk of developing social problems.
I'm not convinced that this is any greater a problem with littermates than it would be with any two puppies that who are close in age, get along, and are being reared together. When two puppies are reared together there is a tendency for the owner to rely on the puppies having eachother as social company. This not only puts the puppies at greater risk of bonding more strongly to eachother than to the owner - ultimately giving the owner less control over the dogs in general - but also puts the pups at greater risk of decreased overall socialization to both other dogs and to humans.
Regarding the instances you have cited, and the question of whether raising littermates is a dangerous venture, there are some potential confounders to keep in mind: firstly, dog aggression fatalities much more commonly involve multiple dogs than a single dog - the "pack effect". So any pair of dogs is more likely to be involved in a serious aggression instance than a single dog - all other factors being equal - regardless of whether they are littermates or were reared together in the same home. Secondly, there may well be a reporting bias towards aggression cases involving littermates... in the same way that there are probably reporting biases involving certain breeds.
I wish I could point you in the direction of more solid data ... but I'm not aware of any."
