More: I’ve heard that Yorkies are not very smart. Chico is the smartest dog I’ve ever had. He gets most commands on the first try. Sometimes if I’m gone for hours, he refuses to eat until I come home. He is gentle and during a thunderstorm he will even jump up on the bed, go under the blankets, all to protect me. I’ve had him since he was 7 weeks old. 2009.
