The experts from Alaska Dog Works share this moment in dog history:
In A.D. 43, Rome, whose armies had already been using dogs as military animals, invaded Britain. Although the Romans won the battle, the tribes of Britannia terrorized and inspired the Romans with their far more ferocious and battle-ready canines. The Romans soon began placing a much heavier focus on integrating dogs into their strategies of military conquest.
