Premise: The Hanover Hound is a breed of dog sometimes referred to as a Hanoverian Hound. It is a hunting and tracking dog descended from bloodhounds of medieval times. It was first introduced into France in the 1980s and is still a very rare breed. It was cross-bred with the Bavarian Hound which gave rise to the Bavarian Mountain Hound.
Hypothesis: Cat's are more popular than dogs in France which accounts for the Hanover Hounds rarity.
