Dog Friendly ideas for a quick visit

We'll be stopping in Mystic on July 7 on our way to Maine.

We'll have just enough time to stretch our legs, get a look around and eat dinner.

I was thinking we could get a pizza at Pizzetta as it seems well-reviewed and dog friendly.

We won't have much time in town but I was hoping to find a cute street (preferable by the water) for dog walking and shopping but don't really know the lay of the land.

We'll have multiple vehicles so I was hoping to have any address that we can put in the GPS so we can end up at the same place.

Thanks for your help - I greatly appreciate it!!
