Gentle 12-year-old dog seeking a quiet retirement home

This is Bamse, a 12-year-old mixed breed I have had since he was a puppy. He is neutered, vaccinated and still healthy, with just a bit of stiffness in the back legs. He sleeps a lot, loves slow evening walks and is calm with people and other dogs. I am being relocated back to Sweden for work and, sadly, at his age the long flight is not a safe option. I am looking for a calm home, ideally with a ground floor or garden. I will include his bed, bowls and food. I am in Chatuchak; please message me in the app.
