Awwwwww Rolo. You really are a handsome boy!! Nice that he enjoys the snow and looks so happy.
Rolo is 14 months now.Rolo looks like a happy pup! I'm sure he's looking forward to warmer weather and no snow....just like you.
How old is Rolo?? You probably should not start biking him till he's at least 18 months of age....till their growth plates have closed.
I've never biked with any of my Rottweilers...by the time the weather got warm enough to bike....it was too hot for them. Rottweilers do not tolerate the heat well...and they cannot tolerate humidity at all.
