Is there a Leash Law in West Tisbury?

 YES!!

"All dogs owned or kept within the limit of the Town shall be restrained from running at large or shall be kept within the immediate control of their owners and keepers."

The common confusion is with the wording "Immediate Control".  Legal definition of "Immediate Control":  Immediate control refers to an area "within an arrestee’s reach".  Which means, you must be able to reach down and touch your dog at all times.  It does not mean your dog is 25 feet in front of you and comes when called.
