Sorry matey, but that statement is totally untrue, theres a few lads that have and do
iv run same dog everynight for 3/4/5 nites a week, not many last tho, 3 seasons is a long time for 1 dog doing a lot imo
I would say that it sorts the wheat from the chaff, imho theres not many people have the work to work one dog absolutely to the max.......they just dont have the time, the fuel money, the right ground or many other reasons.
Most owners would tire long before they could give a good dog all it can handle, its the shite that its easy to spew
