Great Bog is a pet-friendly off-leash area and trail system in Portsmouth, NH, located on all city-owned land. It features unmaintained off-leash trails accessible via rideshare parking. Dogs must be under voice control and under observation at all times.
Great Bog is an off-leash area without full fencing. Make sure your dog has solid recall before letting them loose, and keep an eye on them near any roads or boundaries.
Walking trails are available, so you and your dog can enjoy a walk beyond just the off-leash area. Trails are a great option for dogs who enjoy sniffing and exploring at their own pace.
Best of all, Great Bog is completely free to visit — no membership or daily fees required.
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 folding chair
This park may have limited seating, so a portable chair can make longer visits more comfortable.
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.
Note: Dogs must be under voice control and observation. No dogs on ballfields, tennis courts, or playgrounds. Accessed via rideshare parking.
