Does anyone know of any dog friendly hotels / guesthouses in the Woodstock / Oxford area?
I am looking for accommodation for the CLA Game Fair next summer.

don't know of any off hand but you will find dog friendly cottages etc if you do a google search.i found lots when i was looking the other day, although it depends on how many dogs you want to take with you. 

Try this website, always found it really good. It will tell you which hotels accept dogs.
