There is almost nothing better than watching your dog swim his heart out, and this sight can push your relationship through just about any stage. (In a fight? You'll find yourselves laughing at the dog together. Looking for a way to strike up a conversation? Comment on her dog's Olympic prowess.) For this reason, I humbly suggest McLaren Park as one of the Bay's best singles bars. This is commonly considered the best place to let your dog swim; there's also miles of hiking trails and other, more standard park amenities.
