Irish Mastiff Hound vs American Hairless Terrier - Breed Comparison

Derived from the Rat Terrier, the American Hairless Terrier was born in a litter of Rat Terriers in 1972.

The evolution of this breed is very different from other hairless breeds. The American Hairless Terrier was independently developed when a hairless pup was produced in a litter of normal Rat Terriers. The owners of this pup, Edwin and Willie Scott attempted to breed her to other Rat terriers but were not successful in having another hairless pup until years later. Then they had a litter with one male and one female hairless puppy.

From that point on they worked with a veterinarian and a geneticist to develop the breed until it was accepted as a separate breed from the Rat Terrier in 2004 and accepted into the AKC in 2016.

The breed is very rare and with hairless dogs breeding only produces about two thirds of the litter as hairless and one third as coated. If a hairless is bred to a coated terrier, the chances of getting hairless puppies are 50% hairless and 50% coated. It is very rare to get a hairless when breed two coated terriers. The difference between the American Hairless Terrier and other hairless breeds is that the hairless gene in most breed is a lethal dominant gene, but in the AHT it is a recessive gene.

The Irish Mastiff Hound is a huge dog – a mix of the English Mastiff and the Irish Wolfhound.

Both of these dogs have been around for a long time and actually have ancient histories. The Mastiff for instance has origins that date back to ancient times in China, while the Irish Wolfhound has origins that date far back to 391 AD.

Today this dog is regarded as an excellent companion for any home.

The American Hairless Terrier is similar to it’s breed of origin, the Rat Terrier, and the coated AHT looks very much like a Rat Terrier. They are small to medium in size, very muscular and have more refined features than the Rat Terrier. Their round eyes can be a variety of colors including amber, brown, grey, turquoise and blue. The tail is not docked but rather long and thin.

The AHT might have eyebrows and whiskers or they might only have whiskers. Their head is broad, and wedge shaped with upright ears. They are an energetic, social and intelligent dog.

This is a large crossbreed which can stand at 85 to 91 cm in height and weigh in the region of 47kg to 74kg.

He essentially has the short, smooth coat of the Mastiff but other dogs may well inherit the longer, more wiry coat of the Wolfhound. Coloring of the coat can be quite varied and can be brown, grey, white, tan or black. Some dogs take more after the Mastiff while others have more Wolfhound characteristics. They have a large head, some have a somewhat wrinkly face because of the Mastiff side, the ears are fairly small and floppy and the tail is long.

Temperament:

Even though they're so huge, these are easy going dogs that are able to fit in well with most human families. Described as gentle giants, they are loving, loyal, easy-going, even-tempered and eager to please.

The Irish Mastiff does well in the city or in the country because he isn't particularly active and will be happy to have a comfortable spot to lie close to you, however with such a large dog, you will certainly need a garden.

This is a curious, intelligent, little dog. They are terrific family dogs with a note to say they are better with older children than with younger. If they are raised with small children, then they are terrific with them. They are territorial, and the children become part of their territory. They will guard and protect them.

They need to play, and this is the biggest requirement for owners. Be sure you have time for them. This is not a couch potato dog. They have a lot of energy and can be destructive and “barky” if that energy is not dissipated. They are terriers through and through and love to “go to ground” whether going in holes they find or digging the holes themselves. They will go after small rodents like chipmunks. They need to be protected in these activities since their skin is vulnerable to scratches and cuts from brush. Their prey drive is strong, so it is important to protect them from themselves in this respect.

They are curious and feisty and every inch the terrier. Affectionate, friendly, and social it is also important to remember they can be scared easily, hurt if play is too rough, and this will trigger barking. They make very good watch dogs.

There are not many health problems bothering this sturdy little dog.

The American Hairless Terrier has limited breeding stock and it is still a rare breed. Its health problems are mostly related to its hairless state. The breed is highly susceptible to sunburn, rashes, pimples, and allergies. They often need clothing in all seasons to protect them from the heat of the sun or from the cold. The skin must be cleaned regularly often daily with soap and water. This is especially true if sunscreen is used as they are open to skin infections.

Hip dysplasia is also a common issue for this small breed.

Many people find giant dogs irresistible because they're usually gentle, patient and loving. However, it is their very size which makes them more prone to certain health concerns and gives them a shorter lifespan.

It is why it is so important to ensure you feed your pet a healthy diet to ward off illness. A large dog like the Irish Mastiff doesn't have a particularly long lifespan, and with good care he can get to 9, 10, 11, 12 years of age.

Hip Dysplasia:

This condition is more common in large dogs and it can lead to joint degeneration, arthritis and pain. Your pet may even be reluctant to get up and greet you when you come home which can be very sad. Vet intervention will certainly be required.

Dilated Cardiomyopathy:

This heart disease is commonly seen in large dog breeds where the heart becomes weak so that it can't pump blood throughout the body. Coughing, difficulty with breathing, weakness and lethargy are just some of the symptoms of this disease and will also require veterinary intervention.

The American Hairless Terrier has some food needs that might be different from other breeds. They should not be given food that contains soy, wheat or corn. They need to be fed at least 3-4 times a day in small amounts as puppies and twice a day as adult. Be sure to avoid overeating and obesity. Puppies need about 400 calories a day whether you feed four times or two times. The adult American Hairless Terrier needs about 500-600 calories per day. This might be half a cup to a cup per day.

Health issues

As previously mentioned the American Hairless Terrier has skin health issues and is also prone to hip dysplasia.

Exercise and games

This is a great breed for games if you make them small to match his size. He is energetic, athletic and playful. He loves agility, lure chasing and barn hunt activities. They need a good half hour of vigorous exercise per day.

Grooming:

He has a short coat, and grooming of this laid-back dog will include brushing him twice a week, trimming his nails and making sure that you check inside his ears for ear infection.

Diet:

Large dogs have special nutritional needs, particularly because they are more prone to illnesses such as hip dysplasia. You want to make sure that the foods he eats are rich in Omega-3 fatty acids, glucosamine, chondroitin, amino acids and antioxidants because these will ensure proper joint health.

You've got to be careful what you feed a large breed dog because of the weight management issue too. Excess weight puts stress on the joints and promotes the development of osteoarthritis. Speak to your vet about portion control and meat protein for your pet and how to ensure excellent nutrition to avoid common dog illnesses.

Fresh, cool water needs to be available to your pet every minute of the night and day.
