Australian Shepherd
Despite the name, Australian Shepherds are actually from the American West and were originally bred for herding sheep. "Australian Shepherds are great for families or single people who live an active lifestyle and have room for them to run," says Dr. Sarah Wooten, DVM, CVJ. Dr. Wooten is the vet expert at Pumpkin Pet Insurance. "They are a working breed and need at least an hour of exercise every day. If they get exercise, then they tend to be easy to train, low-key, and great companions." Dr. Wooten warns that if they don't get enough exercise they can become destructive and develop bad habits, so if you want an Australian Shepherd, make sure you have the time to get active. Another trait that some people may see as a drawback is that they shed a lot and require regular brushing and grooming. If that's an issue for you, here are 25 dog breeds that don't shed (that much).
