Well the people at the adoption center think he is no older than 2, based on the condition of his teeth. We are thinking about going to a vet and getting him aged there. The adoption program (11th Hour Rescue) found him on Bridges Road wandering around. They said he must of had a previous trainer because he listens so well. He knows basic commands, like Leave It, Sit, Lay Down, and Rollover. He responds to Samson very well and we have huge plans for him. He loves to give kisses too hahahahaha. Awesome, awesome dog. Gets along with our smaller dog well and he's doing great.
