right off of niagara falls blvd near ficht endle eye(spelling?) and the tim hortons there is a little island you can park and walk over to it. Every weekend there are TONS of people there with their dogs letting them off their leashes to run around. There is also the new LaSalle dog park. I would reccomend getting your dog spayed/neutered before going. Thats asking for some trouble that you don’t want to deal with.
