Thanks Elaine. I'll bear that in mind.
I do stick to the 5 minutes rule when we run, and he gets lots of stops at the moment because I'm not a good runner and I've not really run properly for more than a year, so I need to stop a lot. Plus I'm trying to do it with my daughter and she's only 10 and a complete novice, so I'm more worried its not a good enough walk for him really. He's a worker and he's very fast, so more often than not he sprints off ahead, then has a sniff around while he waits for us to catch him
I'm hoping to improve though, and thought we could build up as he gets older, so I will keep an eye on the breaks he gets if I do get better. I kind of see it as a slower run that I could do just running on my own because there are always going to be wee/poo/play to other dogs stops anyway, but he does seem to enjoy it. He's a w05:
