Introduce the dogs in a neutral location so that your resident dog is less likely to view the newcomer as a territorial intruder. Each dog should be handled by a separate person. With both dogs on leashes, begin the introductions in an area unfamiliar to each, such as a park or a neighbor’s yard. If you frequently walk your resident dog in a nearby park, she may view that area as her territory, too, so choose a less familiar site. If you are adopting your dog from an animal shelter, you might even bring your resident dog to the local shelter and introduce the two there (some shelters may even require that a new dog meets the resident dog before the adoption is complete)
