Being a single puppy we have had to be creative on how to get Peyton not to realize she is an only and not "special". I discovered at Target of all places what is a called a puppy buddy. It is a stuffed puppy with buckwheat in it that you heat up and the puppy can cuddle up to it. This is great, we have also been using it to push Peyton off the nipple, she can't always be first in line, she has to learn to share. I think it is working. It is a lot of work for Doug and I, but it is worth it. Here are a few pictures of her "littermates"
