never lifted a dog over a gate or fence in my life,even as pups,if im going into a field i know they are coming with me,its down to them how they do it,although i will say its dependant on the land you run obviously,which as i say for me,no need
Of course it depends where you run them, as i said my land the dogs have to, they wouldn't fit under or through gates and the fences are mainly sheep netting and only a chihuahua would get through or a small pup! Not saying it's compulsary for all but a 60lb lurcher that couldn't jump would be useless for me!!
