Riley the dog is a bit of an adrenaline junkie.
How do we know this?
Because he followed his owner into an airplane... and then followed his owner out of that airplane before it landed!!
As we previously mentioned, Beagles are often used in labs because of their friendly disposition.
Well the Beagle Freedom Project has rescued some more Beagles from a lab.
These dogs are 2-years-old and have never been on grass before, only knowing life inside a lab.
Check out the above video to see these beautiful dogs take their first free steps.
