We think Rubio is a Ridgeback/Pitbull mix. He’s 3 years old and the most handsome guy you’ll meet. He is standoffish when he first meets new people, but warms up in about 10 minutes. He is house trained, but needs leash training. He is very obedient to his people. He is picky about other dogs – he likes the ones he lives with, but not dogs he passes on the street. He is a strong boy, so he needs someone who can handle him and be willing to train him a bit.
