Australian Shepherd Dog
There are a number of different theories regarding how the breed came to be associated with Australia, but there is no consensus. They are similar in appearance to the popular English Shepherd and Border Collie breeds, and research has found that Australian Shepherds and Border Collies are closely related to each other; both the Border Collie and Australian Shepherd are slightly more distantly related to other kinds of Collies and to Shetland Sheepdogs.
Australian shepherds are best suited for families, but also highly used by police as they are very obedient which makes them very protective of their territories and their owners. The breed is about 18 to 23 inches in height and can weigh up to 60 pounds at a mature age. They tend to be very active and to have a good relationship with other pets. Therefore, they will not hesitate to let you know if strangers approach while being not aggressive to them.
In terms of care, Australian shepherds need their personal space with their bowls for food and drink, be sure not to forget to place a few toys in their area so they can play with them.
