Why do people say that wardogs are a myth unit? To my information rotweilers were bred by Romans for war, so if the Roman factions have them it is perfectly normal.

There is also a legend why rotweilers tails are being cut off. There was a Roman general who used to be the central figure for gossips, he got tired of this and to turn the attention of himself he cut his dogs tail off. Now the people said "Looks what he did to the dog!" and left all his deeds alone. ( This was a very short version of the legend )

But back on topic, I find that the dogs are very good at sieges, I set them loose in the middle of the battle, when my men have breached the walls and are trying hard to kill the enemy. The dogs route them faster and above that even chase and kill the routing enemy so I dont have to face them again or run my troops after them through the whole city
