(Inspired by when I was recently playing Brotherhood and imitated Ezio's "summon assassins" whistle. Whistling in such a way summoned my young dog, who has so far FAILED to be whistle trained/respond to whistles before. She is now my assassin dog XD)

So I want to see any assassin with a pet. But not just any pet, the pet is trained. Trained to help the brotherhood in someway, whether it be messages/trailing/somehow injuring or killing people.

Bonus points:
-One such animal is a cane corso (http://en.wikipedia.org/wiki/Cane_Corso) an Italian breed formerly used as hunt/guard dogs, and if the info from my dog breeder relative is correct, also used in battle against people
-Desmond has one that's a cat (extreme bonus points if it dislikes Shaun XD)
