Beautiful construction on that - how long did it take from start to finish?
If you ever decide you need kennel decks for a portion of the kennel, here is a link to our decks, they are mold and mildew resistant, insect and bacteria proof, chew proof, impervious to feces and urine - so you can just rinse it away...and will not rot or fade in teh sun. It also keeps the dogs off the wood, allows for drainage - each piece is a 2 x 4 and can withstand several hundred pounds:
