A few years back when we moved to our new house, we suddenly found ourselves with a dog and no fence. We tried assorted commercial tie-outs, but our dog then really had no intention of wandering, and it came to the point that we almost never bothered to chain her up. Well, that dog died at the ripe old age of 13, as dogs have the unfortunate tendency to do, and so we have spent most of the last 2 years dog sitting. This summer however, we got a new dog, an incredibly hyper boxer-lab puppy, and it soon became clear that the old solutions would not cut it, so using what we had on hand, I quickly came up with a solution. This is my first instructable, so please be nice, but constructive criticism would be appreciated.

Step 1: Gather Supplies

I know it seems obvious, but you need to have what you need,

1.A rock, I used a rather large, flat slab of rock left by the previous owner of my house
2.U-bolt, you could probably use like an eye-bolt or something, but whatever you use, it has to be longer than the rock is thick. Why? so you can fit it through, you idiot.
3.A chain, to attach your dog,cat,gator,pet rock, etc. to the rock. Maybe not an actual chain, you're probably going to end up using a cable-type thing, available at any pet store. Don't cheap out on this, they do break sometimes, even if they are rated for dogs twice the size of your's
4.Decent drill, you could probably get a masonry drill of some kind, but I'm too cheap, and just used some old drill i had lying around.
5.Water, to keep dust down, and stop the heat from killing your drill, i used a watering can, but feel free to improvise, use a hose, water bottle, super soaker, really drooly dog, whatever float your boat.
6. Cable loop thing. (optional if your chain breaks near the end) i need to stop doing stuff without my camera, but i did, so i can't tell you exactly what this thing was called. It came with some little cable clamps, a metal loop thingy, and some kind of carbiner-looking thing. It's for making a loop in the end of a cable and hooking it onto something. there's a more professional way of doing it, but this is what the hardware store guy recommended for me. Just follow the directions on package.

Step 2: Drill Holes

Drill holes in the rock to put the bolt through. While doing this, i recommend slowly pouring water around the area to keep the dust down, and too keep the heat from killing your drill. Probably a 2 person job, one to drill, the other to poor water. Sorry about the lack of pictures, but this was put together rather hastily, so i didn't have time to take pictures.
Then put the bolt through the hole, and screw on the nut. Hook up your dog and enjoy.

Step 3: Hook Up Your Dog

Pretty self explanatory. You may to choose to dig the rock into the ground a bit, probably not necessary for most dogs, but it will possibly make it possible to mow over, though dont quote me on that. Even on the off chance that your dog can move the huge rock, it should at least slow him down enough to catch.
