I am building a new chain link fence for my yard. How tall do you recommend with a boxer ? 5 ft or 6 ft. I just tore down my 6ft that only covered 1/2 the back yard an could never imagine my previous dog jumping it. Not climbing it but jumping it. Do you think it would be a gamble to put up a 5 footer with a boxer :roll: or should I stick with the 6 footer only?
