The introduction of a dog to another dog is difficult, but there are some proven ways to get things off on the right foot. For example, start by getting both dogs off their feet. You can do this by putting down a bowl of food near the other dog, letting the two interact while you walk away. Another good method is to start by approaching the new dog from behind so that he or she is forced to turn around. Both dogs should greet each other, making eye contact.
