South Arm Dog Off Leash Area at 9206 S Arm Pl, Richmond, BC V7A 2E1, Canada thoughtfully divides the area so small dogs and large dogs each have their own space. Thirsty dogs can drink from the water fountain, and natural shade makes it comfortable year-round. Regulars here are welcoming and their dogs are well-socialized. The ground becomes quite sloppy when it’s wet.
