Looking for someone to find a place with or a room

We're Beth, 31 years old, and Ernie, 2 year old collie x retriever, looking for either a room in a friendly houseshare or 1 other person to find our own house. Ernie is very friendly and cuddly with everyone so would love to live with someone else who loves dogs!

I've been living out of London for the last few years after doing some travelling but moving back for change of scenery! I work in the charity sector and generally work from home 4 days a week.
I'm fairly chilled and in the evenings generally just cook, go the gym, watch tele, read etc. I'm also always up for a trip to the pub and I like to make plans for the weekend to get out and about or take Ernie on an adventure somewhere.

It would be great to live with someone who might be up for occasionally cooking dinner together, going to the pub etc. I'm fairly flexible with move in date and location (either East or South West is my preference). It would be amazing to find somewhere with a small outdoor space for Ernie but not essential as he gets lots of walks and spends the rest of the day chilling!
