When you have a dog that is constantly trying to find a way to escape from your fenced in yard, it can literally drive you crazy! You put up a fence thinking that it will keep your dog safe and sound in their own yard, yet every time you turn around they have managed to get out again. One way dogs escape fencing is to dig underneath. This can usually be easier for smaller dogs, but jumping over or climbing a fence is harder for them. With large dogs, burrowing under can be harder, but climbing or jumping over can be easier because they are bigger.
Even if you remove any items from around the fence line that they can use to help propel them over the top, when dogs want out, they will generally find a way eventually. Fences that are rigid, like wood, help them because they are stable and if they can get their paws over the top lip of the fence, they can scramble on up and over. Chain link is easy because the holes are like little anchors that help them reach the top.
