American Bulldog
Another muscular and heavy dog on the list is the American Bull Dog. The dog was traditionally bred as a working farm utility dog to catch and hold wild boar and cattle, kill vermin, and guard the property. So while they might look pleasant and friendly, especially this one with it’s side-tongue, they are still bull dogs. So if you’re planning to go on a family walk with your little ones, you might have to deal with a fiery, independent, confident and stubborn companion.
Fila Brasileiro
The Fila Brasileiro is another large, powerful breed with a pretty savage and scary appearance. Originating from Brazil, the breed is known for it’s great tracking abilities. Still due to it’s size, and aggressive and impetuous temperament, it has been banned in many countries around the world. So if you don’t want to scare your kids, or anyone on the school run, you might want to give this breed a miss.
