I might be wrong but I think she will take one look at him, get all hormonal, make milk overnight and want to adopt him. LOL. I did have a blue girl, Sweetie, who came into the room where I had two Collie babies penned, babysitting them for a friend, took a short look, then went to a corner of the room, tried to scratch up a nest, lay down and looked under her tail as if to say 'have I had one yet?'. (Yes, she'd had a litter in the past, 11 pups.) So.... it could be interesting. Seeing she wants to lick my sheep and stallion's face I really can't see her getting short tempered with a puppy.
