They're on 10 weeks old, a combo of Collie/Shepherd/maybe Pit, a litter rescued by one of our health care liaisons when she came across mom and pups. We've worked hard to socialize them to "life"! People, other dogs, the vehicle, events, the start of crate work and the leash ... any of the shyer ones, we'd love to find homes with another dog in the home who they can learn from and follow. It'll be important for their development over time. The outgoing confident ones would be fine as a single pet in the home, although training and keeping any pup socialized and being consistent is so important.
