Perhaps the most popular canine hotspot in San Diego is the Dog Beach located at the northern end of Ocean Beach. Here, dogs can roam off leash at any time of the day. Owners should take care to pick up after their pets. After a day at the beach, you may want to head over to the Dog Beach Dog Wash to give Sparky a bath. Located at 4933 Voltaire Street, the Dog Wash is just two blocks away from the beach.
