Tosa vs Bullmastiff - Breed Comparison | Petzlover

The Old English Mastiff as well as the Bulldog are the breeds behind the Bull Mastiff. The Bullmastiff was originally developed in England around the 1860’s. Gamekeepers in England wanted a large, brave, robust dog which could help with keeping poachers away from their large estates which kept game.

As these large estates dwindled, so did the need for the services of the Bullmastiff and later they were simply bred to be family companions. As more Old English Mastiffs were bred, the dog became lighter, so that light tan or fawn became the preferred color.

The breed was officially recognized by the English Kennel Club in 1924, and the American Kennel Club in 1933.

Known also as the Japanese Mastiff, the Tosa hails from Japan. In fact, these dogs come from the Tosa Province, so the dog was named after the region where they were bred.

It is why they are sometimes referred to as Japanese Mastiffs. The Tosa is a rare dog breed and unfortunately, the dog is still used in Japan for dogfighting.

Thought to be a dangerous dog breed, it is restricted in some countries.

The breed was developed in the 2nd half of the 19th century, with a number of dog breeds being involved to bring about a more powerful, braver dog.

Bullmastiffs are large, brachycephalic dogs, and heights are between 61 and 68cm and the dog weight anything between 41 – 59kg. While it isn’t particularly tall, the dog is thickly set with a deep chest and strong, muscular legs. The Bull Mastiff has a powerful build and plenty of strength with an imposing look on his face. He is a powerful, active breed with a short coat which is also weather resistant and can be any shade of fawn, red or brindle.

The dog has a black muzzle and the skull is large and square. The ears are set high and are short and floppy. The tail was once docked, giving the dog an even more distinctive, powerful appearance, but these days, due to regulations, the tail is left long.

The Bullmastiff is a generally healthy breed, but even so, the breed is known for having to contend with certain health issues. He doesn’t have a particularly long life span either and can live to be about 10, ll or 12 years of age. Some of the more common illnesses to look out for include -

Hip Dysplasia:

This is a condition where the thighbone doesn’t fit properly into the hip joint. The troublesome part is that it can lead to arthritis, pain and lameness for your pet.

Bloat:

This is a worrisome, life-threatening condition for a dog, particularly for large, deep-chested dogs such as your Bullmastiff. Instead of feeding your Mastiff one large meal, it is recommended to feed him 2 smaller meals. Bloat occurs when the stomach is distended with gas or air and twists, restricting the normal return of blood to the heart.

The Tosa is a formidable looking molossoid, but even so, this big, calm dog can succumb to illness. Some of these diseases you need to be looking out for include bloat,hip dyslasia and eye conditions.

Bloat for this dog can be life-threatening, and can often be because the dog is too hungry and he gobbles up his food quickly. Bloat is when gas can't escape, the stomach swells and twists – very dangerous. Rather give your dog two smaller meals – one in the morning and one in the evening, or even give several smaller portions throughout the day.

To help with eliminating health issues always choose a reputable Tosa breeder. You’re not likely to find one of these dogs in a dog shelter.

Grooming for Health and Happiness

The Bullmastiff has a short dense coat which is looked upon as low-maintenance. He will require a brushing twice a week, being a light to average shedder. He is a dog that tends to drool quite a bit so you may need to wipe away slobber from time to time. Because his face has wrinkles, check the creases to ensure they remain free of dirt and food particles to ward off infection.

Check his ears at the same time, brush his teeth at least twice a week with special dog-toothpaste and brush and keep the nails trimmed.

Diet:

Your large Bullmastiff will require high-quality commercial dog food but he will also need some home-made food in between such as rice, vegetables and meat. He is a large dog and will have to get an intake of raw meat too. Dogs denied raw meat can end up with skin problems as well as other health issues.It is better to feel your Bullmastiff smaller meals than to give him one large meal which he scoffs down quickly. Smaller meals will help prevent the most dangerous illness known as Bloat.

Ensure he has a steady supply of fresh, cool water.

Diet:

These large, strong dogs do well on good quality food. If you opt to buy him commercially manufactured food, make sure it is the top quality one free of unwholesome ingredients such as preservatives, colorants and useless fillers.

Invest in the best quality ones that have nutritious minerals and vitamins. Try and give your dog some home-prepared food too – boiled chicken, brown rice or pasta, spinach, sweet-potatoes and carrots.

Never feed your dog things such as chocolates, peanuts, crisps, grapes, onion and food with spicy flavorings. This will just ensure digestive problems and having to get your dog to the vet.

Cool, fresh water should be available at all times.

Grooming:

The Tosa’s short coat isn’t going to require too much attention. A good brush twice a week will keep it free from loose hair and keep its shine and gleam. It’s why the dog is looked upon as being low maintenance.

Beyond that, he will need to have his nails trimmed. When brushing him, check him over for parasites – ticks and fleas, check for unusual lumps and look inside his ears for signs of redness.

Exercise:

These dogs are calm and fairly low-energy. Nonetheless, to maintain good health, he will need to be exercised. Ball games outside are always a good idea as well as nice long walks. Hikes into the countryside will be wonderful for this big dog.
