One of the animal helpers I've made is a guard dog to help patrol borders.

Cudions (koo-DEE-ons) are large, standing 30-40" at the shoulder and weighing 65-85 pounds. While they are most often used for patrolling borders, they are also used for herding other animals, making them a mash-up of German Shepard and Sheep Dog. Their coat is short and mottled, giving them good camouflage in the woods. They are hard working and protective, but gentle with the people in their pack. They live 15-20 years.

They were inspired by the Belgian Malinois and the African Painted Dog. Photo(shop) credit goes to Elizabeth Smith Designs.
