Mondo is a 1 yr old chihuahua, he weighs about 5 lbs. He is a bit timid at first,but is full of personality once he gets used to his new surroundings and people. When meeting other dogs he does exhibit a little chi-atude..but responds well to verbal correction, and after a bit of time, does well and wants to play.He comes when called and is loving learning to be a dog :) He is working on his house habits but is doing very well. He also does well in a crate. Mondo is a funny, lovable little guy..he loves to get your attention by doing a little "happy dance" :) and loves to snuggle. That little face is totally irresistible! Because of his size very young children would not be recommended. If you think you would love a little companion that will make you smile everyday..fill out an app for this sweet little guy.
