Walking dogs in East London 365 days a year

This is Khatu and Isha and they're very fit, healthy, and happy dogs.  Their 70 year old East London owner, Dave, is fit too.  The three of them walk about 3 km 365 days a year!  Walking dogs is not just for the dogs!  And to stick to walking dogs 365 days a year is a remarkable achievement indeed.  Well done Dave, Khatu and Isha!
