About the Park
Diamond Dogs Dog Park is a fully fenced, nearly 5-acre off-leash area within the 126-acre Heritage Park along the Great Miami River in Colerain Township, Cincinnati, OH. Converted from a baseball field in 2018, it offers shaded seating, water access, and waste bags for dogs and owners.
infoWhat to Know Before You Go
Diamond Dogs Dog Park is fully fenced, so your dog can run and play off-leash without worry. This makes it a great choice for dogs still working on recall or for owners who want extra peace of mind.
Dogs can enjoy water features here — great for cooling off on hot days. Bring a towel for the car ride home, because your pup will probably get soaked.
Best of all, Diamond Dogs Dog Park is completely free to visit — no membership or daily fees required.
backpackWhat to Bring
Fresh water and a bowl
Even parks with water fountains can have them out of service. Bring your own to be safe.
Poop bags
Most parks provide them, but don't rely on it. Always come prepared to clean up after your dog.
A towel
Your dog will likely get wet at the water features. Save your car seats with a quick dry-off.
A reflective collar or light-up leash
If you visit near dusk, visibility gear helps you keep track of your dog and stay safe.
High-value treats
Useful for practicing recall in a distracting environment and rewarding good social behavior.
Your dog's favorite toy
A familiar toy can help shy dogs feel more comfortable and give them something to focus on.
