Keys on blue lanyard with paw charm

Found a set of keys this afternoon around 3:15pm in the parking lot behind the Santa Maria Public Library on S Broadway. They're on a bright blue nylon lanyard with a small silver dog-shaped charm and a couple of worn keys; one key head is dented and there's a red heart sticker with the initial 'J' on a brass key. The lanyard is in good condition and the keys rattle when I shake them. If these belong to you, DM me here and tell me the distinguishing details so we can reunite them with their owner.
