What we humans won't do for our dogs! We've all heard of the extremes, but a basic dog kennel is a sensible way to create a safe outdoor area for pets to roam and rest. We're talking about a chain-link structure best situated in a location in the yard that's dry, level and shaded from the sun, and that's sold as a kit so it's relatively easy to build. The modular kits - in different configurations and sizes - are a system of frames, mesh panels, a gate and roof panel. The unit is secured with tie-down stakes and anchors hammered into the ground. While some kits are made of mesh panels that fit together, others require stretching the mesh fabric on the frames.

A fence contractor will charge $493 to install a 6-by12-foot gated kennel that's 6 feet high. You can buy a kennel kit of similar size for $330 and install it and pocket a 33 percent saving. You'll find kennel kits sold online and at home and lawn centers and at fence companies. In many communities, an outdoor structure requires a building permit, so check with your local building department to see if one is needed.
