Vampire Fox

Vampire fox is a future descendant of red foxes that became a blood-sucker. Vampire foxes are one of the smallest canines on Earth, only half the size of the fennec fox, due to feeding only on blood. They prefer the warm parts of North America due to their size and very few hair. They are nocturnal so they could hunt larger prey for their blood easier.

Evolution
After the Late Holocene ended, humans are now gone, but not foxes due to the foxes ability to adapt human activities. Eventually, red foxes shrank and started to feed on blood. They lost most of their hair and became more restricted into warm parts of North America. Red foxes had evolved into vampire foxes.
