We did a little research on dog meetups in the United States. A meetup is a periodical meeting between people with the same passion. Those people are members of a group in www.meetups.com and similar websites. Dog owners usually get together based on the breed of their dogs. We found out that dogs in Boston are very social!
In meetups.com, Boston is at the 4th place for number of members, after New York, Philadelphia and San Diego, with 17 dog meetups and 3.167 memberships.
