If you have a travelling dog, or a friend who might have come but didn't want to put her dog in a kennel, the hotel will allow pets for $10 extra. That's $10 extra per stay, not per night.
A fourth of the rooms open onto the inside where there's a lawn (and the pool, which will be closed for winter). That's where dogs can frolic. It's very fenced.
A fourth of the rooms open onto the outside of the hotel, and people can park right outside their rooms that way, motel-style. The other half of the rooms are on the second floor. So if you really want one of those kinds of rooms, maybe request it when you check in.
There are stairs, not an elevator, but there are only two floors.
