Gentle 11-year-old dog looking for a quiet retirement home

This is Bruno, an 11-year-old brown mixed breed I took in from a temple in Hang Dong last year. He is calm, house-trained, walks nicely on a lead and mostly wants to nap in a sunny spot. He has mild arthritis and takes a joint supplement, but the vet says he is otherwise healthy, vaccinated and neutered. My contract in Chiang Mai ends in December and I sadly cannot take him with me. I am hoping for a calm home without stairs, ideally with someone who is home a lot. Meet him near Nimman first; message me in the app.
