Bull Terriers
Renowned for their egg or shark shaped heads and strong muscular appearance, Bull Terriers actually rank first place in pound-for-pound lean muscle tissue. While this is an impressive feat, and they are a little softer than other terriers so not particularly aggressive, they are known to have a strong “prey drive”. This means they can be a little aggressive, independent and stubborn around smaller animals. With the right training, they can be more fun and spirited though. Still, you might have to be careful around smaller kiddies.
Boer Boel
The Boer Boel has a large, stately appearance and is actually a variation of the South African mastiff dog breed. These powerful pups were originally bred to be guard dogs in South Africa and were often used as the first line of defense against predators, like lions. Boer Boel’s were also invaluable in tracking and holding down game. The intelligent breed is fiercely loyal and protective for families, but is also known as a gladiator. So unless you’re looking for a family guard dog, you might want to opt for a more fluffy family pet.
