Here's the ones i used to have. I loved them more than the concrete i have now. Only reason i don't have them now is concrete is better for the property im on now.
Only thing i didn't like about them is a dogs nails will grow very long on wood so you have to keep clipping them. And the water buckets would freeze in the winter even when the buckets on the ground wouldn't.
Space the deck boards out just a little helps drainage. And i liked having kennel at waist height or higher off the ground. Helps them stay cool and keeps fleas down. But i really like them at waist height because its easier to work/treat dogs with injuries etc.
