2. at least one gate to the enclosure
3. a canopy about 20 feet long and as wide as the enclosure to shade more than half of it
4. a wading pool with custom drain: here is a link on how to home-roll one:

5. a large galvanized water bucket with a fastener to anchor it to the chain link fence so the dogs don't tip it over: better yet have two such vessels in case one leaks
6. a insulated dog house with a thermostatically controlled radiator electric space heater inside: a thermometer on the inner wall to gauge the interior temperature: the heater should be partitioned with heavy wire mesh from where the dogs lie down so they can't touch it
7. enclosure flooring: the lightest shade of green K9Grass available for the most summertime coolness, concrete optional, both are rather expensive if you pay a contractor per square foot: in my dog yard you are looking at 250 square feet of ground cover so please do the math, this will be more expensive than the chain-link fencing job by a contractor most likely
8. electronic sonic-activated dog bark controller, battery-operated, water-proof
9. Doggie Dooley septic system
10. a 4 x 5 foot wooden sandbox to train dogs to use rather than soil their turf: this box can go over a bare ground corner of your dog run with no astro turf underneath: you might have heavy wire mesh on the bottom of the sandbox for pee to trickle through into the ground: pea gravel might work better than sand for a toilet area???
11. a fire hydrant urinal for male dogs in the toilet box
Ideally the whole enclosure should be disassemblable and transportable with no permanent posts in the ground. The astro turf should anchor to the fence at the base. This especially important if you are renting a home.
