Lily the Trail Dog is Back! This Pup Flies Down Mountains 7

Lily, the dog that loves to chase bikes, is back! This time the pint-sized Jack Russell is taking her skills and speed to the mountains.

We previously featured Lily in our 7 Trail Dogs That Are Faster Than You feature, and it's awesome to see that she's still got it a few years later. In fact, we think Lily would give the World's Fastest Trail Dog a good challenge, don't you?
