When my dogs were pups I took them out on there own and a tale the bull X out on her own as she has only just started running I'm not angry but there is no need to criticise my method as I wouldn't yours but when your girlfriend is keen to go out as well and brother wht dose t hurt ? The dogs get plenty of slips and are hardly ever sloped together they hardly ever get sliped less than five times in a night so what's the problem ?
