Australian Shepherds took shape on ranches in the American West, where Spanish and Basque herding dogs mixed with collie types to produce a dog with real stamina. Medium-sized at roughly 40 to 65 pounds, they wear a weather-resistant double coat in merle, black or red, often with white and copper trim and eyes that range from brown to blue.
In Manhattan, that working background suits people who spend real time outdoors, whether on the river trails or in a fenced yard. Aussies tend to bond closely with their family and can be reserved with strangers. They're quick learners who want a job, so training, puzzle toys and games matter as much as walks. Without them, herding drive may turn into nipping, chewing or barking.
