While not a residential area, the Miami Government District is home to numerous retail shops, government offices, public buildings, and private offices. All of these are just as likely to be the daytime home of multiple dogs from full-service dogs to emotional support animals. Of course, they all need to be taken for a walk during the day.
The only real problem with having a dog here is that there isn't much in the way of grass beyond the park in the middle of the community. You can take your pup for a quick walk here. Other dog-friendly parks and pet supply stores are a drive from this area. There are numerous tantalizing restaurants to sample and several coffee shops nearby. You can count on warm and sunny weather just about any day of the year in Miami. It does rain a lot here, but it never gets colder than 60°F in the winter.
The terrain here is mostly concrete and brick, made up of flat, paved surfaces. Thankfully, the sidewalks are quite broad and some of them have small areas of grass alongside them for your pooch to do business. Be sure you keep a waste bag handy to clean up after them. The blocks here are large enough that for most dogs, a single trip around is enough.
If you have the time, you can go for another block or two, but be sure you build up your walks slowly. This will allow your dog time for her paws to toughen enough to hold up to walking on cement. Along with this, if you plan to take a long walk every day, be sure to do so in the early morning hours before the sidewalks have had time to heat up. If you wait until the afternoon, the pavement will be hot enough to cause uncomfortable burns.
The government district has a park in the center with a large area of grass for you and your pup to walk on. Beyond this, there are a few small grassy spots worth taking a look at as somewhere to get off and away from the pavement.
If you have the time to take a little drive, there are three larger dog-friendly parks within a short distance. The nearest is the Jose Marti Park on the other side of the river with a small amount of grass, a swimming pool, and baseball facilities. Straight south is Simpson Park, one of the last remaining sections of Brickell Hammock. This park offers 7.8 acres of dense canopy to wander around under.
The other park is Morningside Park, up on the coast. This park spans five blocks and offers a public pool, walking trails, and acres of grass for your dog to enjoy with you at their side.
