Mastiff Information

Mastiff breedSeeing a Mastiff for the first time can be quite intimidating! The breed boasts a large, strong frame ranging from 150-240 pounds for males and 120-200 pounds for females. Along with their colossal size, Mastiffs stand out for their massive head, wrinkly forehead and apricot, brindle or fawn coloring.

Despite their intimidating stature, this breed actually quite docile and good-natured. With their size, training is a must. Luckily, they are quick learners. If you have the room, this gentle giant makes a wonderful addition!

Fun fact: the breed has been around for more than 3,000 years. It appeared on Egyptian monuments and was later employed by the Romans in fights against human gladiators, bears, bulls, lions and tigers in the Coliseum.

All dogs have their own personality and unique training, causing them to differ slightly from these breed stats. However, please let us know if we made an error in the stats, we appreciate your help!
