Puppies are 3.5-weeks-old, and as expected today there were many "firsts". For the first time I heard them "talking" to me and to one another. For the first time they got out of the whelping box, and then I took them outside to a pen where they spent 30 minutes on the grass. Their nails got dremeled, for the 2nd time. They start to resemble "little doggies".
