Donna, I'm soooo excited for you!! I truly am! Don't worry about feeling crazy, or pestering the breeder!! I have a funny story for you....
When my husband and I (now ex-husband) decided to get a dog, we did research and chose a boxer. We talked to a vet who had a client that was having puppies and he gave us their number. (I guess you could say it was a BYB, but really these people had a male and a female and had no intentions of being breeders, but accidents happen... I know better now, and they only had the one litter.) But anyway (that's not the point), we called them up, went over the meet the dogs and decided to buy one of the puppies (which she hadn't had yet). We went over twice before she had them, and put in endless calls of "anything yet?" and "anything yet?". We must have pestered the crap out of those poor people!!

When she went into labor, the mom called VERY EXCITED and said "IT'S HAPPENING NOW!!!" Of course we wanted to rush over, but out of respect for the mommy dog, we waited anxiously until they were two days old. That's when I first met my DEXTER!!! They said we could have pick of the litter, since we were so excited and fired up about having a puppy, and I picked Dexter out at two days old (he still had his tail and dew claws)!! I'll never forget that day! We went over many times to visit the pups and the parents, and made MANY phone calls to check on them.... Dexter opened his eyes for the first time to look at ME!!
Soooo, the point is, don't feel bad about being an excited mommy!! They understand!!

And like most of us here, I could never have let any of those pups go!! I'd want to keep them all too!
I am soooo EXCITED FOR YOU!!! I wish you lived closer to the breeder, so you could have that same experience! But your pup is on the way!!

Keep us posted!!!!!!
