DETROIT Most everybody loves walking their dog. But when the weather gets hot, you need to be aware that hot pavement can injure your furry friend. However, I suspect that the red brick or blacktop surfaces could get hot enough to cause your dog some pain. Heres a suggestion: Instead walking your dog on the pavement, walk him or her on the grass next to the paved surface. Dont let the heat dissuade you from taking the dog (and yourself) out for a little exercise.
