Wow.....congratulations! That's kind of how it was with my Lexie. The biggest surprise with her whelping was that it was a week earlier than expected. But yep, when I saw that she was probably in labor, I took her temperature, and not 10-15 minutes later, we too had our first baby. Lexie had 4 pups also...2 girls and 2 boys.
Anxious to see pics of mama and babies...Congrats again!
