I love these threads.
Here's a few pics of young Jasper, our two year old Boxer. He enjoys our rides on the bike path, as long as it's not too hot and I manage the pace - so he doesn't burnout.
Ears back - aero mode.
He likes his snacks...and "mine" too.
If you want to waste a few extra seconds, here's a very short video of him on a ride.
