I think a magnetic dog collar and leash would be an awesome invention. It would be a cool invention because you don’t need a leash. You would hold a handle that had a button on it that, when pressed, turned on the electromagnet in the handle. The collar would have a metal like iron in it so that when you turned the electromagnet in the handle on, the collar would be attracted to it. You would also have a dial in the handle so you can pull your dog in by turning up the electricity, and therefore the magnetism, when crossing the street. One reason why you would want no leash is that when you’re saying hi to other dog walkers and your dogs are sniffing each other their leashes get tangled up and it’s really annoying, but if you remove the leash that doesn’t happen. Another reason you’d want a magnetic collar is that sometimes your dog will not want to go back when you pull and he can out strength you and outlast your pulling on him, but a magnet doesn’t get tired and would be stronger than him.
