Great looking kennel. I have a suggestion though, cut a piece of outdoor carpet and nail/screw it to cover the doors, and cut back on heat loss in the winter. Worked like a charm for ours.
I have a ? too. From the pictures it looks like your fence barely touches the ground outside, and part of the pen looks like a poured concrete pad. Is the fence buried at all to prevent digging?
Other than those two things it looks great, let us know how the drainage works out outside too. As for the excercise pen, I agree 100% with making it's fence join the extra circle outside around the kennels. That way if they get out while your cleaning or whatever it's no big deal, and then you can open up a gate and allow them into the excercise pen whenever you want. OR if you want to put a dog in the excercise pen and mess with others inside you'll have 3 seperate pens more or less to do so in.
Sounds like those dogs might not want to come out come spring
