Is there a quality grade of chain link for animals ? I have seen
animals at the zoo behind chain link and not ehard of escapes.
Last year I purchased one of those 10 x 10 x 6 ft high ready made dog
pens. It took my German Shepherd about a hour to rip a hole in the
door.
I know have two German Shepherds and would like to to build a long
run. Is there a better heavier grade, like something made for lions ?

Thanks
Jack
