There are several safe, clean places where we can let Fido run off-leash in Miami-Dade. Coconut Grove has several dog-friendly parks; the Beach has some nice locations; there's a spot on Virginia Key where dogs can swim and sunbathe; but of all the canine treats in my Miami, the mac daddy of all dog parks is in Aventura. Two years ago the city, which is burgeoning with young dog-owning families, built the expansive new Veterans Park. The $600,000 two-acre expanse has a wonderful, well-kept, welcoming space. There are pooper-scooper dispensers throughout the space. There are doggy water fountains and doggy showers. And the most endearing detail: red fire hydrants. All of this greatness, of course, comes at a price: You have to live in Aventura, and show proof of residence, to gain access. It's almost reason enough to move there.
