If you fancy a holiday with your dog this year, then I would highly recommend Widget's Farm Luxury Cabin near Bath.  We stayed here between Christmas and New Year and had a fabulous time.  The pod is set within its own private meadow so lots of space for your dogs and you also have the use of 7 acres of secure land to use privately each morning.  Perfect if your pooch is nervous or reactive around other dogs.  There is also a dog friendly pub just a 5 minute walk away - what more do you need?  You can find further details here.  Enjoy!
