Ultimate Mastiff Breed History

The Ultimate Mastiff is a hybrid dog that comes from crossing a Dogue de Bordeaux with a Neapolitan Mastiff. The Dogue de Bordeaux is a Molosser dog, known to have existed in France for more than 600 years. This breed descends from the Molossus, the ancient Roman Mastiff-type dog, and is related to the Mastiff, Neapolitan Mastiff, and Bullmastiff. The Dogue de Bordeaux was very popular amongst French aristocrats for property guarding and big game hunting. The breed suffered highly during the French Revolution, due to its link with the aristocracy, but they were later seen as farmer's and butcher's dogs. The first breed standard was written in Paris in 1896, and they got named after the region they originated in, Bordeaux. The first Dogue was imported to the United States in 1959, where the breed became well-known 30 years later, thanks to its apparition in the comedy “Turner and Hooch” with Tom Hanks. It wasn’t until 2008 that the Dogue de Bordeaux was recognized by the American Kennel Club. The Neapolitan Mastiff origins are traced back for millennia; it is believed that the first Mastiff-type dog was created about 5,000 years ago in Tibet. These dogs assisted in battle and were also used as guardians. After that, little is known regarding the Neapolitan Mastiff's history, until their appearance in Italy. It is known that the breed comes from Naples, southern Italy, from which it got its name. Breeders in this region wanted to create a massive dog for protection, but that would also be a loving family member. They worked on creating a large dog with thick, loose skin. The dogs started to participate in shows and in 1946, the journalist Piere Scanziana found these dogs and worked on making them well-known. Thanks to him, the first breed standard was written and the breed acquired Italy’s national dog registry recognition. They got the name Mastino Napoletano and by the early 1970s these dogs became popular in Europe. It is believed the Neapolitan Mastiff first arrived at the U.S. in the 1880s. The breed was recognized by the American Kennel Club in 2004.

Ultimate Mastiff Breed Maintenance

The Ultimate Mastiff sheds moderately, so weekly brushing is recommended to eliminate loose hair and distribute skin oils properly. She has a short, silky coat. You can use a damp cloth or wipe to remove dirt easily and she will require an occasional bath when smelly. It is important to check out her ears weekly, to ensure she is not having any redness or infections, and to clean them using an ear cleanser and a cotton ball. It is especially important to clean and dry her ears after she takes a swim. You will need to clip her nails monthly, if she doesn’t wear them down. Also, brush her teeth two or three times a week to eliminate bad breath, bacteria, and tartar buildup.

Ultimate Mastiff Temperament

The Ultimate Mastiff is very affectionate, loyal, and protective of her family and territory. They get along well with children and other pets, since they are very caring and gentle with their family. Nonetheless, they can be dog aggressive, particularly with the same sex. These dogs are stubborn, and when bored, they can become destructive. Therefore, it is important to keep a dominant attitude towards your Ultimate Mastiff, and to be persistent in her training. These dogs are very calm indoors, and love curling up in a comfortable spot. They also enjoy playing, running in a yard, and swimming. They rarely bark and are not prone to wander. 

Ultimate Mastiff Activity Requirements

Don’t be deceived by this dog’s tranquil personality, the Ultimate Mastiff requires good amounts of physical activity to stay in shape and healthy. These dogs have a potential for weight gain, so daily activity is necessary. However, it is important to keep in mind that her bones and joints are delicate, so strong exercise is not recommended, especially during puppyhood. A 30-minute walk twice a day, preferably during the morning or evening when weather is fresh, will be well received. As well, as some time to run and play leash-free in a park or yard will be beneficial to her fitness level. These dogs also love to swim, so taking her to a pond or lake will be greatly appreciated. It is important to not allow her to become accustomed  to wrestling or playing rough, it can be dangerous when she is full grown, due to her size and strength. The Ultimate Mastiff is best suited for house living with a fenced yard; they are not prone to wander, but her protective temper might cause trouble. Also, hot, humid weather doesn’t suit her well; fresh climates are recommended, so if it gets hot outside, get your dog indoors.

I have the 1 but my Mum has 2 they are the best dog I have ever gotten my hands on. She’s the easiest to house train and my 9yo daughter has taught her to sit shake etc.. I have a Saint Bernard and she’s very stubborn I find coco is much more willing. My mums are both energetic where as coco has her bursts but is happy to sleep quiet often. She’s very protective of the kids and it’s quiet amusing watching her play hide n seek with them you have to see it to believe it!! I won’t own anything else now once the Labrador and Saint Bernards days are up I want more of these!!
