If you are using a kennel I would recommend putting a roof of some sort on it. My cousin's Brittney jumped/climbed out of it's six foot kennel several times, and even got out when they put a tarp over the top. It is now completely consealed by fence, and the dog no longer gets out.
They had to pay $75 twice when the dog got out because the pound caught him before they found him. So a good enclosure can pay for itself sometimes.
