Enclosures made of Stone, Brick or Cement Block, if it is high enough, it will keep your dog from getting out,  Right? 

Well maybe, if your pooch is the normal run of the mill nice guy. But, if you have an escape artist or one of those born to dig dogs, maybe not.

A stone, brick or cement wall normally sits of a foundation that is only a few inches deep.  And if your dog is a  a real Digger and determined, it will not take long. Since dogs normally dig right next to the a wall or fence, there are solutions.

One solution is installation of a 2 to foot strip of chain link or welded wire fence 3 inches below the ground.  It sure is a lot of work, but it normally works well.

Another approach is to lay 2 inch thick by 12 inch by 24 inch gray stepping stone (they come a various sizes) around the inside of your dog's fence, with a cement slab or slate under the gate. Gray steeping stones is a fancy name plain old cement.

This is far less work than burying the welded wire fencing, but not guaranteed to stop a really determined large dog. The author had a 88 pound male Samoyed who though those cement things were part of his yard's exercise equipment. Once the cement blocks were recessed in the ground, his digging became much more difficult.  Instead of the gray steeping stones you could use some of the fancy Pavers, but they are more work and cost more. And your pooch may have more fun removing them.

All enclosure require maintenance, in the case of  Stone, Brick or Cement Block Walls, Gates are a major concern. Like everything else in your dog's life, your attention is required to keep your friend safe.
