good pics again , but im not alover of lots of dogs on qaurry , prefer one maybe two at most on a sett, never pups and never young dogs i would do it with oldeis who have done it as to them no big deal , my freind lost a dog runing into another dog out a run bit bigger than them ,my old saluk cross bitch would love that type of day but the young collie cross in her prime would want to have ago with terriers etc if they tried to stop the fetch etc , and come near her cacth , some dogs you can have fun with others are to serous and dont lke dogs near the sett or even neer there rabbit if they ha
