I have to say that I'm amazed and perplexed that anyone would allow their dog to tresspass on their neighbor's property. I realize that it's a dog's nature to sniff the scent of other dogs so why not go to open areas where they can walk and sniff to their heart's content and stay off the hot pavement at the same time. It's not whether or not it ruins the grass, it's trespassing, I watched a woman allow her dog to go up to a flower bed and pee on the rose bush. What is the mentality behind that, is it a sense of entitlement?
