I have a lovely dog (actually i have two) who always wants to run away. Yesterday, i spent nearly 3 hours playing with my dogs, walking them, giving them attention and he still runs away. The thing is, whenever he sees a person he wants to greet them. Yesterday he jumped down this (it's 2m10 high )



Sure he was hurt, but not enough to scare him in the future. What can I do to prevent this? Tips anyone?

He's castrated by the way.



Ps: for people who haven't seen one: the red pavement is a REAL cycling lane
