I love that there are beaches you can walk your dog on in San Francisco. Fort Funston is big and always packed with hundreds of dogs and their people. A great place to hike and get some exercise and fresh air with your well-mannered pup. Not recommended for antisocial dogs; there's just too much commotion there.
Dog parks can be a fantastic way to socialize your dog, but it's important for owners to understand that a dog park isn't exercise and isn't a substitute for walk. A visit to the dog park is fun - play time.
I'm a dog person; I've had dogs all my life.
A lot of times in parks the large dogs and little dogs separate. That creates the opposite of social. Sometimes dogs run back in forth with a fence dividing them so it is fence fighting with social interaction.
Who let the dogs out? Who, who.
I go dog-walking a lot.
I've grown up with dogs and love dogs.
I grew up before there were strict leash laws.
Dog parks are more cliquish than any other human gathering with the possible exception of seventh grade. Deal with it.
