a group of us stayed here last year. You can have dogs in some of the cottages I think, we certainly had one in our group.
It might not be what you're looking for but it was good, not far to anything, nice big garden although there are other people around but we found it fine (but we had 4 of the houses!)
There is indoor pool and ping pong etc which you can use. Cottages are all very well appointed (to use tourism office speak!) but essentially we found it great.
