Eagle's animal control code used to be vague. In April 2024, the City Council unanimously passed the most comprehensive ordinance rewrite in the Treasure Valley, 24 pages of new rules covering leash control, the definition of "at large," fence maintenance, and the Boise River Greenbelt. If you live in Eagle and walk a dog, the rules changed under your feet, and they're worth knowing.

THE SHORT ANSWER

Where can my dog be off leash in Eagle, Idaho?

In Eagle, dogs must be on a physical leash on all city property, parks, and the Boise River Greenbelt. Eagle updated its animal ordinance in April 2024, one of the most comprehensive rewrites in the Treasure Valley. Off-leash is permitted only at the Eagle Large Dog Park (along the Greenbelt) and in designated areas within Eagle Island State Park. The Idaho Humane Society enforces.

Eagle's Off Leash Laws: What the 2024 Ordinance Update Actually Changed

The April 2024 ordinance update wasn't a tweak. It was a full rewrite. The previous code was vague, and the new one is specific and enforceable.

The biggest change is the definition of "at large." Under the new ordinance, a dog is at large if it is not on a leash AND not at a dog park AND not immediately responsive to verbal or non-verbal commands. There's a narrow exception for highly trained hunting and working dogs with demonstrated voice control, but for the vast majority of Eagle dog parents, this means the leash stays on outside of designated off-leash areas.

The Boise River Greenbelt is specifically called out. It's a daily-use corridor for Eagle neighbors and an active enforcement zone. Off-leash citations on the Greenbelt are real and they do happen.

A few other points from the new code:

Fence maintenance. Owners are responsible for keeping their dogs contained. Citations can be issued if a dog escapes repeatedly and is found at large.
Enforcement. Idaho Humane Society.
City Code: Title 4, Chapter 5, with dogs at large covered by 4-5-7

Where Your Dog Can Go Off Leash in Eagle

Eagle Large Dog Park (Gateway Parks)

Location: Along the Boise River Greenbelt at the Eagle/Garden City border
Type: Unfenced. Voice control required at all times inside the park.
Boundary rule: Leash required entering and exiting the park boundaries
Amenities: Drinking water, restroom, trail access
Restrictions: No aggressive dogs. Children under 13 must be supervised by an adult.

This is Eagle's main off-leash option, and it's a real one, but the unfenced layout means your dog needs reliable recall. The voice control requirement is enforced, and the leash goes back on the moment you step outside the boundary.
