Seeking home for me and my lovely dog

Looking for somewhere either small and self contained, or a buddy up to find an entire rental. This is for myself and my mature girl dog who doesnt bark, is well trained and friendly. She has arthritis and therefore likes to just relax, eat snacks, and not make a fuss. It will have to be ground floor, as stairs are a no go for her now.

I am a working professional in the area of healthcare, who is easy going, nature loving and enjoys travelling. I enjoy a healthy balance of socialising and having my own space. Ideal place would be somewhere simple, with space for some belongings, so something such as a studio/annexe/mobile home. However, I am happy to buddy up with someone to share an entire rental, but I'd like that to be for just myself and 1 other. 2 or 3 bedrooms, depending on if they would want their own living room and the cost limitations etc.

Can provide references from previous places stayed, for myself and Roxy (my dog) :)
