The length of the body taken from the point of the shoulder to the point of the buttock is greater than the height at the withers. The AKC standard height (per their website) for this breed is 30 inches (76 cm) at the shoulder for males and 27.5 inches (70 cm) (minimum) at the shoulder for females. A typical male can weigh 150–250 pounds (68–113 kg), a typical female can weigh 120–200 pounds (54–91 kg), with very large individuals reaching 300 pounds (140 kg) or more. Long haired Mastiffs, known as 'Fluffies', are caused by a recessive gene—they are occasionally seen. The AKC considers a long coat a fault but not cause for disqualification. . When purchasing a purebred Mastiff, experts often suggest that the dog undergo tests for hip dysplasia, elbow dysplasia, thyroid, and DNA for PRA.
