Rosie is 4 pounds and we run for 4 miles. She loves to run. I usually get tired, but she keeps me going because she wants to run. Haha. At then end I come home ready for a nap, but she brings her toys and drops it on me to play. We have gone as long as 5 miles too, but usually we run and walk in the 5 miles.
I guess it really depends on the dog. Some dogs don't like to run and others love to. |
