Why don't you want to kennel your dog? As long as a dog is being worked (exercised) properly, they don't need a big kennel run -- 6' or 8' X 10' or 12' is plenty big enough.

A dog must be either :
1. Supervised or
2. In a fenced area (and Wayne1 is correct, an Underground fence IS NOT really a fence).

Also, Cutter -------- Take a look at the left side of your keyboard --------- see the key that is named "Caps Lock" ??? ----------- well, give it a tap. (Typing in all Caps is called "SHOUTING" and is very uncool.
