Household manners, vet visits, 4-H, that sort of thing, can be acheived even with a "doggy" dog, as long as that dog is of a good, safe, and biddable temperament, and well socialized. A lot depends on breed, too.
When you get into higher levels of competition or real-life work, the subtle differences between a dog-oriented dog and a human-oriented dog become more apparent.
The thing you have to be aware of with multiple dogs raising each other and running together, is that they have a pack mentality. If they are more dog-bonded than human-bonded, if it ever comes down to a human vs. pack worst case scenario, they're going to go with the pack. Meaning, if they all decide to go through a hole in the fence and attack the neighbor's sheep, you can yell and scream until you're blue in the face and your dogs will likely ignore you.
An experienced person can succesfully have several well-behaved, well-trained dogs run together (depending on breed), if each dog is worked and trained individually. But many people simply get two puppies "to keep each other company", because they DON'T have as much time to spend with each one, and they figure they will entertain and exercise each other. Which works great, until those puppies reach adolescence and start fighting, or become so bonded to each other that they do not care about humans and cannot be separated from each other.
