spot on, imo it relates to a lot the dog men I know.. Travelling hundred of miles not just in a season but in a week, walking miles and miles a day up the fells in horrendous weather, training a dog every day in all weathers, lamping in cold and wet weather of back of the van or walking, keeping it up year after year even decades is a obsession. Slightly mad aswell, but I think you need that bit of madness to keep going. We probably all know someone who fits the description wether of here or personally..
