Put out his water and food bowls with strong smelling food, put out your dirty laundry for a scent, blanket, shirt etc. Walk when looking for him to leave a scent trail, Walk big circles around your home several times for a scent. He can smell you far away. Check cameras in the area. Contact a dog tracker if need be. Put flyers up, give one to your mail carrier, post one at your local convenience store and bring one to the shelter when you go to look for him in person. Look on animal control & shelter sites in case he was picked up.
Praying he's safe and home REAL SOON 🙏 ❤️
