Mine is 6 feet - to no avail. Bailey can get out whenever she wants - though so far, she only climbs up and looks out. In my opinion, there is no "safe" height. Your boxer will either be an escape artist or she won't. If she is, no fence is gonna be tall enough to stop her!:D
mine is only 4ft high, chain link, trudy went to jump it one day, crashed into it, it shook and clanged and she hasn't gone near it since...but if i had a choice I would feel much better with a 6ft privacy fence.
We have 6 feet around the yard and the dog run area is about 4ft high. They haven't gotten out yet but I am going to give Jack 6 months and I am sure he will clear it. I already take his collar off cause he's a jumper. I would go for 6ft.
My next fence will be a 6-ft. wood privacy fence with a 3-ft. wide shelf around the inside perimeter about 6" from the top. I *think* that will keep them in the yard The 6-ft. wood privacy fence by itself doesn't - I have one (of five) that can get over it. The other four don't, have never tried - they never even tried to jump the 4-ft. chain link fence.
Lexi did meet the meter reader eye to eye over the 6 ft privacy fence in our old house one time, but has never attempted to jump the fence. We know our gazelle could clear the thing if she wanted but she never attempts to. She does however try to squeeze out under the utililty gate:rolleyes: Now I have heard of people using chicken wire around the top of their fences to keep their dogs from jumping over--anyone use this with success?
I really wouldn't like to put a measure on how high a boxer can jump
Monty fools us....he has to be lifted into the boot of the car...he will put one paw up but then I have to heave him in. However only yesterday he jumped a 6 1/2 foot wall.....I was out in the fields and picked up a stick and tapped the top of the wall to get his attention.......he came flying and simply lept up onto the top of the wall and stood there wobbling trying to balance on the loose slabs of stone....boy did it scare me....he lept back down but that was more frightening...I was terrified he'd break a leg.
Thats the last time I do that silly thing again.
