Pets are welcome on the grounds surrounding the visitor center and the developed areas of Elliott Key as long as they are on a leash and attended. With the exception of service animals, pets are prohibited in other islands of the park.
- Pets are not used to fending for themselves and need access to fresh water, food and pest-free habitat which the park does not provide. Animals abandoned in the park are likely to perish from dehydration or starvation.
- To help an animal find a proper place to live, contact a local rescue such as the Humane Society, This is the Dog!, Pet Partners Rescue Home, Marrvelous Pet Rescues and Born Free Shelter. It is a crime to abandon an animal in Miami-Dade County.
- Loose pets are a danger to park resources. Loose cats, for example, kill wild birds.
- Spay or neuter pets and keep them in safe habitat.
