Saw this at my vet's office and had been looking for something like it to put on the front porch of our house. I ordered one, they sped it to me and we put it up the same day it arrived. It works so well for our 60lb black lab/hound dog (Kasey, aka 'the runner'!) She is now able to enjoy our Colorado sunsets with us thanks to the dog hook. We have a brick house so ordered the masonry hardware kit and it went up easily and is very attractive. We will recommend it to all our dog loving friends and family. Thanks for a great product.
