The MASTIFF is among the Working Group!
For the uninitiated, a face-to-face encounter with these black-masked giants can be startling. Standing as high as 30 inches at the shoulder and outweighing many a full-grown man, Mastiffs make an immediate and lasting impression. The rectangular body is deep and thickly muscled, covered by a short double coat of fawn, apricot, or brindle-stripe. The head is massive (a word that comes up often with this breed), and a wrinkled forehead accentuates an alert, kindly expression.
