A dog park in Pacifica would benefit not only dogs and dog owners, but also the community at large. Some of the benefits include

For Dogs

1. Exercise. This is especially important when for any reason; the human cannot walk their dogs. Alternatively, when the sidewalks are icy and humans are
afraid they may fall. In addition, dogs will exercise more when they are
off-leash.
2. Socialization. A well-socialized dog is a better-behaved dog
around other dogs and people. They are less likely to be aggressive,
to bark a lot, or to participate in obsessive behaviors like digging.
3. Fun. Let's face it; it is much more fun to explore a park with
new sights, smells, dogs and people than it is to spend time in the
back yard. Again, troubling dog behaviors usually manifest themselves
when a dog is bored (digging, barking, etc.).
4. Safety. If a dog park is designed correctly and monitored
correctly, it provides a safe environment for humans and their pets to play
and exercise. Dangerous cars, cliffs, or other hazards can be avoided.

5. Dog behaviorist like Dr.Ian Dunbar, Dr. Jean Donaldson, Ceasar Millan and the list goes on, all agree dog  to dog off leash play is critical.

For People

1. It is fun to watch dogs interact.
2. Or better yet, humans can exercise with their dogs, walk the park
or play ball.
3. Enjoy the great outdoors.
4. You get to meet others dog lovers and share ideas regarding
training, dog products, and dog friendly activities.
5. The dog park provides an opportunity to train your dog in a
new, more challenging situation.

For The Community

1. Well-socialized dogs are friendlier dogs and this means fewer
dog attacks and less annoying behavior.
2. Parks designated for dogs keep other parks and beaches dog free.
3. Every dog parks should have a bulletin board where the Humane
Society can list the pets they have for adoption and promote
membership. Members of the dog park can also use this to post
information and announcements for fellow dog park users.
4. The ability to meet fellow dog lovers and to post information on
a dog park bulletin board might ensure that pets found new homes
BEFORE they were surrendered to a shelter. OR, it will help dogs
better fit into their homes because exercise and socialization
decrease destructive behaviors and owners are less likely to get rid
of their family pet.
5. A dog park would provide a place to hold dog friendly events; Bark in the Park, Agility Training, Canine College all in a safe,
dog-friendly environment.
6. An accessible dog park provides disabled and elderly people a
place to exercise their companions.
7. A dog park might tempt people off the Hwy who are traveling with
pets. Several travelers plan their  lunch/dinners breaks and overnights stays around the presence of dog-friendly
places.  This could mean more business to Pacifica 
8. Finally, a dog park promotes responsible pet ownership.
This benefits the dog, the dog owner, AND the whole community!
