well the best bitch we have had at lampin used to run at a jogging pace but would use her brain rather than speed to catch her quarry..
not very exciting to watch but very efective...
the only problem she would run the same during daytime and didnt put the effort in to catch em.
was a bit too cute for her own good but still a great lamping bitch...
so if yours is not putting her all in but catching the quarry then you have to live with that...
if not then i dont think you can change the way your dog is running..
