The American Gentleman

Originally bred as fighting dogs, the Boston Terrier is one of the most loving and gentle dogs around today. The breed is named the ‘American Gentleman’ because their black and white coat resembles that of a tuxedo. The Boston Terrier is a very affectionate breed, making them perfect additions to your family.

The origin of the Boston Terrier is very unclear. No one has been able to pinpoint how this breed came to be. There are many speculations and assumptions, but none that have proved to be factual and correct. This breed falls into a group of dogs called brachycephalic. This term means that the dogs lower jaw is in proportion to the body, while their short upper jaw gives their faces that pushed look.

Prone to having sudden bursts of high energy, these dogs need plenty of exercise. So be sure to take them on walks with you and keep them active.The Boston terrier can be a tad bit stubborn, but standing your ground and being patient with them is vital.

The Boston terrier blends incredibly well into family life. Their size is not too small and not too large either, making them great companions for children.
