they are a very time consuming hobby,more so imo if they live outdoors alone.
and don't forget circumstances change.
when i first got my lurcher i worked 40 hours a week monday to friday and it was easy,now i work 7 days a week between 70 and 82 hours and have to get in a fair bit of training as well,so even just looking after the dogs to the bare minimum (cleaning out kennel,walking,spending some time with them each day etc) does become a chore sometimes,let alone actually working them.
