When Luc was 8 he was regularly running distances far in excess of that - a bit younger, but his longest run is 40k (just under a marathon). When he was 8 he was still regularly running 5-20k at least a couple of times a week, and he did an 80k hike in ~20 hours over 2 days.
Running will not create hip problems, though if your dog has hip problems, it may exacerbate them. I'd start slow and see how your dog does. A daily run of 1 mile should be good exercise for your dog though, it's a gentle introduction and will allow it to build up muscle. I say go for it and see how it goes!
