Good deal..Just make sure your shade is good enough for all day.Sun moves all day long so if you have a dog that lays in his dog house at any point of the day then you don't have good enough shade.
Yup already looking at some large refurbished pool covers that can be cut to whatever size you want. I want them big enough to cover the entire chain spot. 22' x 22' should cover the entire area but not allow the dog to run around the post holding the shade cover up
