I find it to be really mean to see a dog owner play with their animals with a flashlight as if it was a ball to chase. I don’t think it is satisfying for the dog to never accomplish catching the forever bouncing ball. My neighbor does this with his flashlight and a laser light he bought for this reason to tease his dogs. It breaks my heart to watch his dogs run up and down the fence line back and forth with me knowing there is not ever doing to be achievement of actual catching the ball. He thinks it is so funny on their enjoyment trying to get it. Is this right or wrong to do this to a dog? I personally, believe it will make a dog always be looking for any light (s) that appear his vision. Regardless, I believe its just sad.
