hi, im new to the forum and new to working dogs im a young lad and for my first dog my dad bought me a big bedlington dog,whos trainings coming on well for saying hes ten months, he stays whilst a balls throne then fetchs and retrieves when ordered to, soon i'll be getting some ferrets and was just wondering whether its worth getting the mk3 or an older model just for starting out, i have plenty of land to work in the season. thanks
