Teressa,
On a happier note......I think that if you are feeling like you would like another pup right away, then go for it! I instinctively knew that Lady was going to die quickly when she became ill. I brought Tess home on a Saturday and Lady went over the bridge two days later on Monday. We still grieved for her very much and we didn't try to kid ourselves about Tess replacing her. Different pup, different love. In my situation, it did help though since it took up time I would have spent mourning and it also helped to have the pit-pat of Boxer feet still in the house.
Good luck with whatever you decide!
