Lost set of keys with a blue rubber keyring near Potsdam-Canton-Massena park containing house and car keys.

I lost a set of keys that has a blue rubber keyring attached to it while walking my dog near the Potsdam-Canton-Massena park. They're pretty important as they have a few house keys and a car key. I've looked everywhere but haven't been able to find them. If anyone has seen them, please let me know!
