Where does the Ultimate Mastiff come from?

The Ultimate Mastiff is a designer dog, one of the larger ones, a mixed breed from two purebred parents. Celebrities and the public are increasingly becoming enamored of designer dogs and that popularity has gone up over the last thirty years. Designer dogs have a mixed reception amongst some dog lovers though, as unfortunately it has attracted a lot of bad breeders and puppy mills breeding mixes with no care just to make money. Make sure you research the breeders you are thinking of buying from.

Despite what some might promise there are no certainties with these dogs. Some might get the best of both parents, some might get the worst and many have a mix. Even puppies from the same litter can vary in looks and temperament. To get an idea of what goes into the Ultimate Mastiff we can look at the parents origins, appearance and personalities.

The Neopolitan Mastiff

This is a giant breed of dog originally from Italy bred to be a large protector of families. Today he is still very much a guardian rather than an attack dog. He is steady and even when he seems most relaxed is always alert and aware of his surroundings. He is affectionate to his family but aloof with others and his size and his strong will means training and socialization needs to be started early otherwise he is quite the unmovable mountain!

The Dogue de Bordeaux

The Dogue de Bordeaux or the DDB comes from Bordeaux, France around the 14th to 15th century. He was bred to be a guard dog with his strong body, power and fearlessness. The dog in the big hit Turner and Hooch with Tom Hanks was a DDB and his popularity in America has increased since.

Today as well as still being an effective guard dog he is affectionate with his family and strongly loyal to them. While he can be docile and sweet natured and also has a stubborn bull headed side to him. When it comes to training he needs someone with dominance, skill and patience. It is important this dog has early socialization and training to calm any aggressive tendencies towards other animals or strangers he thinks should not be in his territory.


The Ultimate Mastiff is a dog who can be easygoing, sweet and affectionate but also has a strong stubborn side and is very protective. With help he can get along with other pets and children. He has a big personality to suit his actual size and can be playful and loving and very loyal. He needs an experienced owner who can deal with him when he is being bull headed.

What does the Ultimate Mastiff look like

His coat is short, straight and silky and colors include tan, gray, black and brown. His ears are flappy and his teeth should meet in a scissor bite.

Training and Exercise Needs

How active does the Ultimate Mastiff need to be?

This is a dog who needs a fair amount of activity just because of his size. He will need at least a couple of brisk long walks each day and would also enjoy things like trips to a dog park, going for a run or hike, play time and so on. They have webbed feet and are great swimmers, he also runs fast and jumps high. He needs access to a yard and some mental challenges too. A bored and under exercised Ultimate mastiff can become destructive. He is not suited to an apartment due to his size and his need for a yard or some outdoor space.

Does he train quickly?

This is not an easy dog to train, he is stubborn, bull headed and needs an owner with experience and who can establish dominance. Firm and positive with consistency is the best way to train him. He will likely challenge your leadership and you need to be ready for that. Early socialization and training are important and you need to stick with it. If you find you are having difficulties seek professional help, there are school and professionals who can help. Do not leave him untrained.

Living with a Ultimate Mastiff

How much grooming is needed?

He is has moderate grooming needs, needing his coat brushed at least three times a week. He sheds a moderate amount so some vacuuming will need to be done after him and you will have hairs on clothing. He will need to be bathed when he needs it, if there is not a space to do it easily in your home look for a groomers with a bathing station. Use a dog shampoo so that you do not damage the oils in his skin. After bathing and swimming be sure to dry his ears thoroughly. His ears should be checked once a week and wiped clean too. His nails need clipping when they get too long and his teeth should be brushed at least three times a week.

What is he like with children and other animals?

With early socialization and training he is good with children, he will play, be affectionate and protective of them. He can also be good with other pets and dogs. Children should be taught how to play and touch him safely and younger ones should be supervised just because of his size in case of being knocked over.
