Dogs crave friendship just as people do. To help your pet make friends: Walk your dog regularly, and go to parks where dogs congregate. Create a profile for your pet at Dogster.com, so you can meet other people and their dogs. Bring your pet to a doggie day care for a few half days. Ask the staff which dogs yours plays with so that you can contact the owners and arrange playdates. Join an obedience class to meet owners of dogs that are compatible with your pet.
