The Ultimate Mastiff is a cross between the Dogue de Bordeaux and the Neapolitan Mastiff breeds. It is a giant breed that has a very stout and muscular stature with a long tail, and a wrinkled face with hanging ears, almond eyes, small nostrils, and a short snout opening in a wide mouth. With their affinity for swimming, these dogs have developed webbed feet. Because of their possessive demeanor and various whims, they are dogs mostly suitable for experienced owners.

Temperament and Behavior
The Ultimate Mastiff dogs are primarily sweet, loving and easygoing. They also have a loyal and caring nature. These are traits that would at times instigate them to become overly protective of their owners guarding their properties, also making them act obstinate, or like a dullard, despite being intelligent. It is, thus, easy to infer that, they would take to barking at the slightest provocation to warn their owners. These dogs are swift by movement and can jump high and run fast. They also love swimming.
Care
Exercise
Needless to mention, vigorous activities is a must for this highly energetic canid. They would need a couple of quick hikes, leashed walks or jogging sessions every day. They are also in need of an unleashed playtime inside a safe enclosure to burn down their high energy. Participate in games and activities along with other members of the family. Considering its love for water and swimming, it would also be great if you have a swimming pool right at home.
Grooming
Your dog has short hair, and hence, grooming requirements are minimal. Brush them at least twice a week to discard dead hairs. We must also mention once again that, letting your dog swim from time to time would not merely keep it happy, but also take care of its bathing needs.
Health Problems
Like many other large breeds, because of their body weight and playfulness, they might be prone to picking up orthopedic issues like joint and other dysplasia quickly. Heart and eye problems, demodicosis, fold dermatitis, and cleft palate might also appear in some. While most of these issues are inherited, it is advisable that you learn about the health history and facts of their parents thoroughly before adopting one from your breeders.
Training
- In order to cut down chances of possessiveness/territoriality, expose your dog to more and more new faces. For example, while you invite your friends to your house, hand over treats (or even gifts/toys) to them so that your guests give them away to your puppy with their hands. Say, a cousin is visiting you for lunch with her cat. Ask her to tie a small fun toy from its collar. First, let your dog notice the toy before it gets it.
- To impart an overall good behavioral training you can consider puppy training classes, where your pet can learn lessons on socialization and obedience.
- Because your large dog might often act whimsical, let it get accustomed to the leash while it’s still small. You can implement the leash training from time to time while indoors, and always when you are outdoors.
Diet/Feeding
Considering their large size along with high levels of energy, 4.5 to 6 cups of high-quality dry dog food is what they need daily. Divide this into two parts for lunch/brunch and dinner. Remember, these dogs are prone to gain weight quickly.
