When I was younger, at the same time I was running dogs, I also ran for my local athletic club, track, road and cross country. Just to give an idea of my fitness standard, my times for 10k-32mns, 10mls-56mns, 20mls-2hrs,you get the picture, well I've taken dogs on long training runs, bedlington,deerhound,collie and saluki crosses. The only ones that I didn't have to stop and wait for were the saluki crosses. It might sound far fetched to you lot, but believe me it's true.
