How do I introduce my new dog to my dog? General Dog Discussions
From my experience of introducing my mastiff with my mini doxie I can tell you that they will act differently when on a leash than when they are loose. We first tried to gradually introduce them by letting them see each other, then smell each other, then get closer. But the dogs seemed to be more protective that way so we separated them. Then one day we let the mastiff in the house with the doxie on accident and they sniffed each other then quickly became friends. My mastiff knows not to be too rough with the little guy and they get along great now. As long as neither dog is aggressive I dont think their would be a problem. You may want to try to introduce them at a neutral spot like the park or a neighbors yard. Your older dog may feel protective over "HIS" house or backyard. Either way I would still keep a good eye over them when they first meet, and be ready for anything!
