Lost Dog in Tosa

Our dog got out last Monday and we no leads on finding him. Thought to post here in case someone might be able to help. Jedi is a 16.5 year old, white Maltese. He cannot see or hear well, so will likely not come to you if called. He also has very few teeth left. He is typically friendly if you pick him up but may not be if he’s truly been outside for a week on his own. He is not chipped and does not have a collar. We have been checking on Madacc daily and have posted on socials and passed out flyers. Figured I would ask here in case someone sees him or knows anyone who picked up a dog in Tosa last week. I appreciate any help you can offer.
