What a Spanish Mastiff’s height measures

Height is measured at the withers, the top of the shoulders. The head and ears extend above that line. The Fédération Cynologique Internationale standard gives Male minimum 77 cm; female minimum 72 cm. No upper limit; over 80 cm male and over 75 cm female desirable. Choose the sex or size variety above where the source separates them. A range describes the published listing, not the height of every individual dog.

Ranked by the tallest height its standard names (30.5 in), the Spanish Mastiff is the 8th tallest of the 297 dog breeds on this site. See the tallest dog breeds ranked.

Drawn at the same 30.5 in: Spotted hyena. Same drawing, different listings: a Spanish Mastiff’s figure is a minimum, a spotted hyena’s the lower end of its range.

This is a published species or breed reference, not a prediction for an individual animal. Where a range is supplied, both ends appear with the reading. Shoulder height and head height are kept apart when comparing animals.
