Hi, Oh yes Berners can jump four feet:-) I have a five foot chain link and a friend's bitch popped over that with no problem. I have a bitch who was staying at a friend's and she liberated herself over a four foot fence gave the poor woman a nervous breakdown, sent me into orbit and just as I was about to hit Warp speed in my van the word came that dear Maggie was sauntering up my friend's driveway having had a nice explore of the neighbourhood. Shortly after that she went over the top of a six foot run but I think the landing bruised her and she now is a somewhat overweight older lady still good for four feet though!
