Week four! They have begun to go outside on warm days for a little while each time. It is very useful about the time I need to change the blankies in the whelping box. They are using the litter box better than past pups have picked up newspaper. The wood pellets absorb the moisture better and keep the whole room smelling woody...better that than the other.... When the pups went outside and Remi could see them walking, I think he finally figured out that there might be a potential future in these little squeaky things. He should enjoy playing with the pups as they get a little older.
