The Boer Boel is a large, mastiff dog breed from South Africa which was bred for the purpose of guarding a home or farm.

These dogs were often a first line of defense against predators and were valuable in tracking and holding down wounded game. Bore Boels are loyal but very protective of their families.

In 2002, Romania prohibited the import of the Boerboel, and restricted ownership to those with a court order allowing them to own the dog.
In 2010, the Boerboel was banned in Denmark for being a fighting dog.[14] In addition, it appears on the Wikipedia list of dog fighting breeds.
In 2011, Russia deemed the Boerboel an “especially dangerous breed,” subject to mandatory registration and certification.
Ukraine classifies the Boerboel as a dangerous dog, subject to mandatory microchipping, muzzle, and civil liability insurance.
