We have a small dog so require dog friendly hotels or cottages.
I really struggled to find dog friendly accommodation, but maybe I had left it a bit late - booked in November 2017 for Easter 2018. Did eventually find a wonderful cottage in Port St Mary called Langton Holiday Cottage. We found the Isle of Man to be very dog friendly and lots of great walks, although some of the beaches have restrictions May to September. Could take dogs on the steam train, electric rail etc.
