Large and muscular, it is believed the Rottweiler lineage could go all the way back to the herding dogs of the Roman empire.
However, we do know for sure that this breed was used to herd and guard livestock in Germany.
It was also used to pull carts loaded with meat for the butcher – so you know it's pretty strong.
In World War I, Rottweilers found all sorts of jobs as police dogs, guard dogs and, of course, as draught animals.
Devoted, alert and fearless, the ‘Rottie' has all the ingredients to be a protective dog.
Thanks to their genetics and history of breeding, these dogs naturally have strong guarding instincts.
Whether it's their home or a flock of animals, overall, they are often unsure of new people and strangers which can bring out that protective instinct.
Combine that with their sheer size and that's a pretty intimidating dog.
