My best all round dog was a 5/8 x 3/8 . We were out a lot at night, then he was out with the terriers Saturday and a foot pack Sunday’s . Whatever you threw at him he d do it . Was a handy dog on an earth and lamped off the lead, really obedient. When I put him down to old age I had dogs with a higher bull percentage ie first crosses and reverse 5/8 x 3/8 . All game but none as good all rounders as my old dog . I tried 3 3/4 gh x 1/4 bulls. They could all shift but had no bottle . Yes you d have foxes with em but they were vocal when they got bit and fxxxed about with stuff when a bit sore .
