I have a 7 year old, 70#, Newfoundland/Golden dog who needs more exercise than I can give him.  I have four stress fractures in my hips and sacrum.  He’s very sweet, very gentle, very strong, pulls hard on his leash, and will take off after a bunny in a heartbeat.  

Is anyone interested in volunteering to walk/jog him?  He could probably only jog a mile to start with and he can walk ~4 miles at this point. 
Thanks much,
Lorry
