For a medium-sized dog, the Majorca Mastiff, often called the Ca De Bou, has a rather intimidating look, largely thanks to its Molosser-type build. But despite its thick, muscular body, large head and seemingly even bigger mouth, this breed is actually not only gentle and friendly, but surprisingly social. They've long been raised as watch dogs and guardians in their home country of Spain, more specifically the Balearic Island of Majorca, but have also long ago started their transition into that of a companion animal as well, thanks to their excellent overall temperament. The breed has quite a history, with speculation of their origins spanning back centuries, their jobs throughout time spanning from herding and guarding to bull-baiting and show dogs. Even today, their personalities still retain traits indicative of their history, yet they've rounded into a much more versatile dog than their earliest years. Although their overall numbers are on the rise thanks to a relatively recent surge of interest and popularity internationally, they are considered one of the more rare of the Molosser-type dogs - although that may not be true for long, given that breeders have now spread throughout Europe, even if in small numbers, and the age of the Internet has now connected once-isolated groups of enthusiasts.

Marjorca Mastiff Breed History

Like many ancient breeds, the history of the Majorca Mastiff is largely up to speculation, but there does seem to be evidence to suggest that this breed descended from the Iberian Mastiffs brought to the Balearic Islands by King James I in the 13th century. It is believed that once arriving, they were bred with other fighting, guarding, and herding breeds but it would be centuries before enough official documentation surfaced to have a written account of their development. From the start of the 20th century, things began to move at a much faster pace. The first written mention of the breed surfaced in 1907, suggesting they may have been more well-known than first thought in the 19th century. By 1923, the Ca De Bou was listed in the Spanish stud book and by the end of the decade, the breed had already been shown in the Barcelona Dog Show. Unfortunately, like many breeds that were on the rise in this era, they were highly affected by both World War I and II, as well as the resulting famine, trimming down their already limited numbers. A breed standard was eventually developed in 1946, but it wasn't recognized by the World Canine Organization until nearly two decades later in 1964. By that time, there were no purebred dogs left and their progress was further limited by the surge in popularity of dogs like Great Danes, German Shepherds, and Rottweilers. Fortunately, the 1980s helped to turn the breed around thanks to a renewed interest and the eventual crossbreeding with theĀ Ca de Bestiar, a large, more lab-like breed also native to the region. Since the crossing of the two was not rare, breeders stuck to those with stronger Ca De Bou lines and features. The breed was further reinvigorated in the 90s with the age of the Internet helping toĀ familiarize and popularize the breed internationally, spreading the formation of breeding groups all over Europe. Today, their numbers are still on the rise thanks to select groups of enthusiasts, but their future health is already starting to become threatened by French puppy mills and other substandard breeders looking to capitalize on their newfound popularity.

Marjorca Mastiff Breed Appearance

The Majorca Mastiff is a medium-sized dog, standing just under two feet at the withers and weighing between 66 and 84 pounds depending on the sex. The sex can usually be identified by the head alone, as males possess a larger total circumference. Their heads are large and broad with an almost boxy appearance, a strong stop and a similarly-broad conical muzzle capped with a large black nose. Their eyes are large, dark, oval, and widely spaced and their ears are small, rose, and high set. Their necks are strong and nearly the same diameter as their heads. They have a deep, broad chest that creates a wide-legged stance in their well-muscled forequarters and terminates with only a slight belly tuck. Their topline is almost v-shaped between their withers and hips and it is considered a fault for them to stand taller at the prior than the latter. Their tails are thick and tapering and have a slight curve. Their coats are short and somewhat rough, coming in black, fawn, and brindle with white permitted on 30 percent of the body.

Marjorca Mastiff Breed Maintenance

Majorca Mastiffs are considered low maintenance dogs as they require little tending to outside of the basics. They are only average shedders if not less and take brushing only a couple times a week with a firm bristle brush to keep their coats clean and their natural oils properly dispersed. They rarely need a bath unless they get into something offensive and generally keep themselves clean naturally. Their rose ears aren't particularly susceptible to infection but should be checked occasionally to make sure there is no excess wax or moisture buildup. Their nails should be checked and trimmed regularly to prevent any issues with breaking or cracking and their teeth should be brushed at least once a week to avoid tooth decay and gum disease.

Marjorca Mastiff Temperament

Despite their history as bull-baiters, guardians, and hunters, the Majorca Mastiff is a surprisingly affectionate dog. They are known to form strong bonds with their families and will go to great lengths to protect them. Because of it, they are often distrusting of strangers and will position themselves between the newcomer and territory/family as a form of intimidation, only turning aggressive should they feel they or their families are threatened, making them exceptional guard dogs. Of course, this can also be trained out of them, especially if addressed early on, although they are relatively strong-willed and independent thinkers, so thorough training will take a firm, consistent, and experienced hand to exercise dominance. Majorca Mastiffs are generally good with other dogs, so long as they are number one in command (number two with a good owner) and generally do better with more laid-back breeds that will not try to assert their dominance, as they can become combative otherwise. They also generally do well with all types of family members, including children, but should be trained and socialized early on to get the very best of their potential behavior. Once they have been through both, they generally adore children and are quite patient and gentle with them. Although they are highly-adaptive to their environment, they generally do better with space to play and run, as they require a high level of exercise, so an active family with a larger home and yard are preferable.

Marjorca Mastiff Activity Requirements

Because of their size and considerable muscle mass, Majorca Mastiffs require a high level of exercise to stay happy and healthy. A total of 18 miles of walking and running weekly and 60 to 70 minutes of exercise daily should be enough to tire them out. Once fully trained and socialized, they generally do well as jogging companions, but also enjoy running and chasing things in a yard or dog park. Keep them entertained both physically and mentally by including them in family activities. Engage them while outside and bring them along on outings whenever possible.
