Look for room rent or forming a houseshare

I have lived in a small detached barn-conversion on a Farm in an outlying village from Uckfield for the last 5 years, but it feels like time for a change and I would like to share with 1 or 2 other people now for the company and affordability to move back to my preferred location of Uckfield (although would consider Newick or Buxted).
I currently have an old but very clean and friendly parsons terrier that lives with me - but he is really in his dotage now so unsure at this point whether he will still be going as it were by the time I am looking to move in the new year. So I need to give top consideration to room rentals or houseshares that he might be a part of being a priority at this time.
