There are some dog umbrellas that do not come with a built-in leash. Some, however, do come with a leash attachment usually in the form of a hook or clasping mechanism with which to attach an ordinary dog leash. However, this may not work well with the umbrella since you will need a relatively short-length leash to connect to your dog’s collar so that it stays well within the protective cover of the canopy. If the leash is too long, its body may move outside this protected area.\r
