Amstiff History

The Amstaff is a generic term that refers to several closely related types of medium-sized working and guard dogs. The term “AmStaff” is often used to refer to the common ancestor of all modern American Pit Bull Terriers and Staffordshire Bull Terriers. The Amstaff was popularized in America during the early 1900s, when pit bulls were being mixed with English Bulldogs, Boxers and other terrier-type dogs. Today the Amstaff is considered to be a “foundation” or “type” of many different Pit and Staff types, such as the Staffordshire Bull Terrier, the American Pit Bull Terrier, the American Staffordshire Terrier, the Pitbull, the Mixed Breed, and the American Bully.

Amstiff Activity Requirements

Amstaffs are a muscular, medium-sized dog with a stocky body. They are strong, athletic, and intelligent. Amstaffs were once used as hunting and guard dogs, but today they are mostly companion animals. Amstaffs can be high-energy, high-maintenance dogs. They love to be active and will often try to herd other animals or people. They need a daily walk, but they can be prone to digging, jumping, or chewing, and may need additional training. If you have a high-energy Amstaff, you will need to provide them with an outlet for their energy. They are best suited to homes with a large yard where they can run and play. A daily walk is also important, but you may need to limit the amount of time they spend off-leash.
