Dogo Guatemalteco vs American Mastiff - Breed Comparison

Known as the Guatemalteco Bull Terrier or Guatemalan Molosser, the Dogo Guatemalteco is also known as the Bull Terrier Guatemalteco, Guatemalan Bull Terrier, and Guatemalan Molosser.

This big Molosser-type dog originates in Guatemala. In the 20th century, it was known as the Bullterrier Guatemalteco, but at the end of the century, it was changed to Dogo Guatemalteco.

Today, while the dog is kept as a companion dog, most are working guard dogs. The Dogo Guatemalteco isn’t recognized by any major international kennel clubs. However, the Kennel Club of Guatemala has given full recognition to this dog and it was in 1981 that the Guatemalan government named the dog as their national dog breed.

The history of the American Mastiff is entirely tied to the old European Mastiffs but in particular the English Mastiff. The developers of the American Mastiff crossed the English Mastiff with the Anatolian Mastiff at the Ohio kennel, Flying W Farms. The founder of this breed is Fredricka Wagner. Because of this the English Mastiff and the American Mastiff look very much alike. The difference between the two is that the American Mastiff was bred to have less health concerns than the English Mastiff and without the drooling. In 2000 the CKC acknowledged that the American Mastiff and the English Mastiff were separate breeds.

The Guatemalteco is a medium to large dog standing at 54 – 60cm and weighing between 40-45kg. He has a short, smooth coat and is essentially white with some black markings on the head.

This breed was created from a crossing between a bull terrier, boxer and dalmatian. Some of the dogs are thickly built, while others are more leaner and athletic looking.

He also doesn’t warm easily to strangers.
