I'm sorry we don't allow dogs inside. We do however welcome well behaved dogs out side. The Four Horse Shoes down the road is dog friendly.
Not sure so suggest you contact the pub directly. However, I do know there is outdoor seating.
I have never seen a dog in the Pub. There is very comfortable outside tables and chairs for a summer visit though.
Having a couple of dogs myself, I understand your predicament., it's worth a phone call, they are a "country pub" so you may get lucky. As far as I could tell all areas served food. but my husband half remembers a dog swanning about ( thinks it may have belonged to the manager).
