Do anyone use to raise single puppy? My CK who is about 3 weeks old has no playmate.Nowaday,his mom leaves him alone sometimes though she still nurses him very well. In my opinion,he seems to be lonely when he's alone.What a poor boy.What should I do to cheer him up? I don't want to spoil him but I don't want him to grow up with bad habit if any too.
