Our amazing Oso! He is an 18 month old mastiff mix. He can be a bit unsure when first meeting someone new but then bonds quickly. He LOVES to play! Especially ball and makes the funniest noises when he sees you! We have not yet dog tested but he seems non reactive. He came to us from a home with cats and was interested when he met our tester cat but may be ok. He seems to like kids but we prefer to place him in a home with teens and older due to his size.
