Dog Policy

Dogs on leash are permitted at Grand Ravines North year round, but on trails only from May 1 through September 30. For the safety and enjoyment of all park guests, pets must be on ten foot leashes and under control. Dogs are permitted year round, off leash at Grand Ravines South. Owners must clean up after their pet and dispose of waste in a trash receptacle. Leader dogs for persons with disabilities are permitted at any time. Recognizing that most dogs enjoy running and playing freely, Ottawa County Open Space Lands allow dogs year-round off leash.

Coming Soon to Grand Ravines South

Premiere off-leash dog park
Includes 21-acres of enclosed dog park, with separated fenced areas for large and small dogs. Additionally, there will be fenced trails for off-leash walking.
The Parks & Recreation Commission has already built the parking lot and support facilities and has allocated $75,000 toward building the park, but that will only pay for fencing and trails. In order to include the amenities that will make it a gold star facility, we will be seeking funding from local businesses and residents.

Additional funding is for:

  • Water service and doggy fountains
  • Lighting
  • Waste stations
  • Additional paved paths and benches
  • Modern restrooms
  • Picnic tables and a shelter area

A local pet store, Chow Hound, is already on board. Chow Hound has committed to matching customer donations up to $10,000, for a maximum donation of $20,000. With Chow Hound’s pledged support, we are 25% of the way there.

Visit your local Chow Hound or contact the Parks Office with questions or to make a donation: 616-738-4810. Please help us spread the word!
Stay tuned for our unveiling of the dog park this fall.
