    "Everyone here has a dog, maybe multiple! The dog park is nice, and friendly and the apartment complexes are mostly pet friendly. We have a dog who loves to walk around the neighborhood and we always pass others with dogs. Not everyone picks up poop but there is a ton of doggie stations for bags! Personally we were inspired to get a dog because so many people had one here already and we wanted to join in on the fun! Main Street is pet friendly too and the Katy trail is a great path for dogs.
