I stayed here in 2007. Although I didn't take a dog, the hosts welcomed them. They have a retriever of their own that is friendly and pads around the guest house.
The B&B is located in one of the most beautiful locations (in my opinion), with some fantastic walks quite literally on the doorstep. The place was clean, the rooms and food were fab, the hosts were lovely people and it did seem to be a pet friendly place.
Give them a try - Im sure you won't be disappointed
