It is believed that the Irish Wolfhound is an ancient breed and that it was brought to Ireland as early as 7000 BC.
These dogs were bred as hunting dogs as well as guard dogs. There was a time when these huge canines were only allowed to be owned by the nobility. The breed died out somewhat, but Scotsman Captain George Augustus Graham made efforts to restore the breed’s numbers.
Captain Graham devoted his life to making sure the Irish Wolfhound’s numbers were built up, and the breeding program included Great Danes, Borzois, English Mastiffs and Scottish Deerhounds.
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.
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.
The tallest of the sighthounds, the Irish Wolfhound looks like a large Greyhound, only he has a rough, wiry type of coat.
He is also gracefully built and known as a gentle giant. The double coat which can be fawn, red, white, grey, black or brindle is straight to wavy.
He stands at about 81 to 86cm and weighs roughly 48 to 54kg. This is one of the few dog breeds that you can’t really call social. He loves his own human family, and becomes unhappy and ‘down-in-the-dumps’ when separated from his family members for too long. He is a quiet dog who tends to be somewhat introverted and reserved, while being highly intelligent.
He will require being trained and socialized to make him obedient as he is an independent dog. He takes his role as family protector seriously and even though he is quiet, he is ready to take on anyone who threatens his property.
The Irish Wolfhound is a gentle, quiet, soft-natured, easy-going dog and even though it is such a large dog, it doesn’t throw it’s weight around but is calm and patient around the elderly and children in the home. It can tend to be aggressive with animals he isn’t familiar with.
He is an intelligent dog, but even so he may be quite resistant to training as he is strong-willed and determined to have his own way. These dogs need to be trained and socialized otherwise they just do their own thing.
The Tosa is a large dog, but their sizes vary, and in fact, because of their fighting, they are actually divided into light-, middleweight and heavyweight classes.
Generally, you can say that these dogs weigh in the region of 54 to 90kg and they stand in height at between 62 to 82cm. The head is large, the jaws powerful, the eyes dark brown in color, the ears small, high set and floppy.
The neck is broad wit a dewlap and the tail is long, thick and tapering to a point. The coat is short and thick and is most times a rich caramel color, fawn tan, black or brindle. The dog often has a black mask.
The Tosa is a fairly quiet dog, courageous and fearless. He is going to need a strong, consistent owner who shows leadership with him. Training and socialization will be imperative for this dog.
When he has been properly reared and trained, he makes a good pet, able to get on with members of the family. He takes his role as protector and guardian seriously.
The most notable aspect of the Irish Wolfhound is his amazing height. The legs are long, the body narrow. He is gentle and easy-going but because he is a sighthound he loves to give chase after animals.
He is capable of living in the city or countryside, but your home will need to cater to his size. He isn’t particularly energetic, enjoying a quiet life but he will absolutely need to be exercised.
Provide your gentle giant with everything needed to make him content, and you’ll have a faithful, loving friend for about 10 years.
The Tosa isn’t recommended for first-time dog owners, as in the wrong hands, they can become aggressive. Care has to be taken around children too especially undisciplined ones.
He also doesn't come as recommended for small, cramped homes in the city. He’s just too big and he will need to get out and be walked often.
You want to create a home for him that ensures he is the calm, gentle dog he is capable of being, If you’re fair, firm, caring, patient and consistent, then this big dog might be for you. With the right care he becomes a gentle, devoted pet.
One wonders why breeders seem so bent on breeding such large dogs when they have health issues and they don't live particularly long. Not only do they cost a fortune to feed, but large dogs like this are more prone to illnesses and won’t live as long as small dog breeds. This big dog can live up to 10 years of age or so.
For starters, just because he is a deep chested dog, bloat or gastric torsion can be a threat. Other illnesses to look out for are dilated cardiomyopathy and bone cancer.
This is a disease of the heart muscle where the enlarged heart won’t function properly. The upper- and lower chambers of the heart are enlarged and the heart isn’t able to pump blood out properly. When the heart’s ventricle doesn’t pump enough blood into the lungs, fluid accumulates in the lungs and this ultimately leads to congestive heart failure.
Older dogs battle more with this heart disease and it is also more common in some dog breeds of which the Irish Wolfhound is one. Your dog will have shortness of breath, coughing and abdominal distension. He will need to get to the vet for medical tests.
Bone cancer can strike any dog, but you’ll find in more commonly with larger dog breeds. It can spread quickly and the long term prognosis isn’t good. It’s not easy to pick the disease up and it can mean joint pain for your pet and even lameness.
Your dog will be tired too. Your vet will do X-rays and other tests, but unfortunately the prognosis isn’t usually good. Big-dog breeders should take this into consideration.
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.
This isn’t a particularly energetic dog and he can tend to become lazy. Don’t allow this as becoming unfit and overweight can be very bad for such large dog. Being so large already puts stress on the dog’s body, and the dog is already susceptible to cardiac and skeletal problems. Allowing him to become lazy and overweight will be a death sentence for this large dog. It is imperative to make sure you take him on walks and play games with him.
The coat of your dog is thick and medium length and he will require being brushed at least twice a week. You may want to also trim the longer hair you find around his face and legs.
When it comes to his ears, you can moisten some cotton wool and wipe the inside of his ears to remove dirt and excess wax. Remember not to probe too deeply to avoid damaging the ear. If you’re uncertain how to do this, your vet can explain to you how its done.
Check his teeth regularly as dental disease can affect other areas of the body too. Don’t allow his nails to get too long as they can cause paw problems and the nails can hook onto things and cause injury.
Because this is a giant breed, the puppy will grow for a long time. Speak to your vet about how to ensure you feed your puppy in such a way that he doesn’t grow too quickly.
If you feed your dog a commercially manufactured food, make sure its one of the top quality brands. Include home-made cooked food such as chicken, rice and vegetables into his kibble from time to time, and also try to feed him some raw meat occasionally.
Fresh, cool water must be available to your Irish Wolfhound around the clock.
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.
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.
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.
