Like LeoRose said, it is 4 times the work to have two puppies. If you plan on keeping both, you should make sure they are separated from each other far more than they are allowed to play together. They need to bond to their humans, not another dog. If they are allowed to bond to each other, this develops into anxiety when they are separated from each other. So if one dog has to go to the vet they're going to become very anxious and inconsolable when the they are separated. If you want to take one dog for a walk but not the other, it's not going to happen.
Dogs are perfectly fine without another dog family member. There are single dogs in families all over the world, and they're fine! It's okay for dogs to be bored, too. They need to learn to settle and sleep or chew on a toy when you are not playing with them.
