Just pulled an all-nighter whelping pups. 8 total and the last one arrived at 7:30 this morning. Surprisingly, out of a yellow-factored black sire and dam, half the pups were yellow. Turned out to be a real nice mix: 2 yellow males, 2 yellow females, 1 black male and 3 black females. Now the bosslady and I can take turns catching up on some sleep.
