Gizmo is about 6 years old. He is about 85/90 pounds. I think. He is good with other dogs as long as they do not try and alpha dog him. If they are chill, he is chill. In regards to shots, we are not sure about that either. I am guessing because my mom got him from a shelter, he is all up to date on his shots but I really have no idea. I have not seen him around kids but he is good around the older humans that I have seen. We do not know his past other than the two years my parents have had him. He is chubby, my mom walked him many miles a day but she probably overfeed him because of her memory issues. He is a sweetie and likes to go on walks. He likes to play and also lounge around. He is a good guard dog and will let you know if something is different than usual.
