Our ornamental fence contains pickets and hairpin hoops so the space stops your pup's access. Perfect doggie fence
with vertical spacings at 3.25 inches.
Our customer installed this fencing (pictured) very well, stair stepping it down a hill slope.
Susan, a co-owner here, tried to get her small 12-pound Maltese named Dory through the puppy pickets, and Dory didn't go through the fence (see Dory fencing picture below).
