Dogs are required to be leashed everywhere except at your home, and at city designated off - leash area. Leashes are mandatory everywhere else. Seniors may have balance and mobility issues, some people are scared of dogs and some just are not interested in their snot on their trousers. Leashehing your mutt keeps it happy as you will be the ALPHA and it knows it's place, it is safer when near traffic, and lastly won't leave a disgusting turd that you can't locate to take home and compost environmentally. Your Dog Is Not My Best Friend. Put a leash on it!tshirt-sample-1b.jpg
