The vet was here Wednesday and gave everyone their first round of puppy shots and a clean bill of health. 3 of the boys had an undecended testicle, but the vet said that is not uncommon at this age. Mama's milk is officially gone and they are eating dry puppy food. They have access to the outdoors all day and they love to run around in the snow. The use the puppy door all day, coming and going as they please. We put a litterbox with wood pellets in their kennels and they actually use it about 50% of the time for their #2.
