When we built our house, I knew we would have Shady for a while. Shady is my Dad's dog and when he moved to the Assisted Living Home, we took her on.
Shady loves to dig. When she was younger, no amount of fussing by my Mother or scolding by my Dad would stop her. So we made her a place to dig. Just a space filled with soft sand. I wet it when it is hot outside so she can make a cool spot.
She loves it!!
My friend and landscape designer suggested this, and she said many people bury a kiddie pool in their yard to hold the sand. Makes much more sense than scolding a sweet old dog. Especially Shady.
