> i had to hand feed RC starter mousse while in whelping box
Very, very important point made here. It is amazing how many inexperienced breeders expect a bitch to get out of the whelping box and eat her dinner!
Some bitches would rather starve than leave pups. I routinely hand feed in the whelping box. I was gobsmacked at the skeletal boxer bitch I saw at a friends. She put food down
in a different room 
and then told me that her bitch wouldn't go into the kitchen to get her dinner!
I despair sometimes. There are far too many people that think breeding is a piece of cake, and expect a bitch to "get on with it."
