One more rodeo?

We are looking into collecting and freezing a sample from Rambo, and possibly trying artificial insemination in a year and a half. There are 2 facilities in Houston that look promising! I really wanted to wait 18 months in between the last litter and this one, but I didn't want to miss out on an opportunity to make more gorgeous and well tempered puppies before Rambo is neutered at the end of the summer. I have had several people who really want a puppy from Stella and Rambo (or a second puppy), but the timing isn't right. We are dying to keep one too, and if we don't keep one this litter then definitely the next litter. I say that, but we would happily keep them all right now- especially if I can't perfectly place them with families.
