If city-dwelling dog owners know one thing, it’s that their pups need a place to run and play. The city has a handful of dog-friendly areas in park districts and community-run parks for dogs.

The city’s first dog park, Wiggly Field, was created in 1995. Now, over 20 such play zones exist citywide, primarily downtown and on the North Side. As long as your dog has its dog-friendly area tags (just $5, available through most veterinarians), he or she can play without restraint.
