She's an English mastiff -- big dog! She actually looks almost small here, but she's about 30" tall at the shoulder and weighs 165 pounds (her dad was 35" and 245, yikes!) Mastiffs usually have a short, smooth coat but she got the recessive gene for a long coat, so she often gets mistaken for a Leonberger. She's the sweetest, most affectionate (*cough*needy*cough) dog ever :)
