well here goes lads/Lasses,many moons ago i was out with a 7 month pup collie x greyhound up in a little place called coldingham [berwick].we were out for a few rabbits on a turnip field when my pup took a bunny ,as he was retrieving it a fox came from no where and actually ran at the pup who then dropped the rabbit which ran away. this same pup turned out to be the best fox dog i ever owned and took fox from 11 months onwards i dont know if his earlier experience had owt to do with it but boy this dog hated them with a vengeance
