I attached Oreo, a pit-bull mix, to my bicycle using a special leash. But instead of leisurely jogging alongside me, she pulled my bike - and 160-pound body - for nearly 8 miles around the island like a tiny nuclear-powered horse. And the next day she was ready for more.
But that's just a fun anecdote.
Are pit bulls really the most active, high-energy dog breeds? What about huskies or malamutes, the great powerhouses of the Iditarod? Or your deranged Boston terrier?
To find out, Tech Insider asked Whistle - a company that makes a GPS and activity-tracking dog collar - what the most active dog breeds are based on the data they see from the roughly 150,000 Americans who've used its products. (Like all data, this set has limitations - see our notes at the end.)
Here are the top 43 of the most active breeds in the US, ranked by average minutes of activity a day.
