Hi @Allie173 Greetings from 38 miles down the road from you!
- It is unlikely that any host in remote rural Scotland will ever see this! - This is a forum for Airbnb users, primarily hosts, to support each other over hosting issues, have a moan, ask advice, & connect with fellow hosts across the world. The vast majority of hosts don't bother posting, tho' who knows how many others pop by without posting, or 'thumbs-upping?!
Have you tried messaging hosts directly in the Arisaig/Morar/Mallaig area?
Have you tried 'Spare Room'? (UK lodger/tenant site.) I just had a look and nothing in immediate area... -A cheaper option than Airbnb for long-term lets, as there is no commission/booking fees, which make Airbnb expensive for more than a few days...
I guess in your situation the dogs will be a problem for many landlords ....
Good luck!
