Chihuahua 3 Years Old Guido is a little guy with a lot of spunk and heart. This healthy little Chihuahua likes other dogs, doing zoomies around the house, taking strolls and sun bathing. He wants to be your best friend and faithful companion, he takes time to warm up to people as he is very protective. Guido has made tons of progress since being rescued as far as trusting and not being so nervous around others, which is why I would not recommend small kids for him. He is a perfect dog for adults who want a small companion to take on walks, does great in the car and can just chill. His love is unconditional and his heart is as big as his head! He listens well, protective and very smart! Crate and House trained, walks well on leash and loves to run errands in the car and does very well.
