Here are a couple pics of Casey's kennel.
The first pic shows the footing/foundation. The entire perimeter is concrete that goes down 24" - this keeps a dog from digging out or other critters from digging in.
The fencing is 8' high. The front 1/3 is a cement pad that is covered with "astro turf", and has a roof with a snow deflector and rain gutter. The rear 2/3 has dirt to dig inhe goes clear to the back to poop), trees to pee on and bushes to lay under.
On the pad, is his dog house (Dogloo) which I fill up with Grass Hay in the winter - he stays toasty warm even in the coldest winters. There is also a 'motion detector' light that comes on when he moves around at night. In the summer, I put his Kiddie Pool on the pad. There is a "teather ball" that hangs down from the inside of the roof. The gate is lockable.
