it depends on how old the dog is, from 12 weeks to 1 year, 5 mins per month,but i never let them puppie off the lead for free run untill a year you can get all the basic training with in that year on the lead ( expect for nutty tehya she just a happy fcr but we are getting there with her) then aftre 18 months once the bone and joint stop growing and settal down,then it all go,
but it like human the more work out you do in the gym the more you want to do beacuse for the homeones,and i have found that with the dogs the more excersie they get the more they get restless and want more,my auntie has is with fcr,
