It doesn't look like much, just a big square of vacant land with a few benches thrown around, but for your pet this park is like doggy Disneyland. Cooped up all day while their owners are making a living to keep them in Kibbles, the canines are turned loose at Poinciana Park. There is no snobbery, cliquishness or breedism among dogs here. Dobermans, beagles, and golden retrievers run together, fight playfully, and roll on their backs on the soft grass. The socialization is good for the dogs, say owners and trainers, and the pooches clearly appear to be enjoying the freedom to romp. But it's also a social experience for the owners, who stand around like parents watching their toddlers play, trading tips on dog collars ("Where'd you get that mood dog collar?" asked one owner), food, and discipline problems. One caveat: You have to watch where you're walking. Apparently few follow the park's scooping rule.
