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.
Known also as the Canary Mastiff, the Presa Canario hails from the Canary Islands. He was originally bred for guarding livestock.
This isn’t a new breed by any means, and it is believed that the dog dates back to the 15th and 16th centuries. The roots of the dog can be traced back to the Iberian Presa, a medium sized mastiff breed. A number of other Hispanic breeds have contributed to the formation of the Presa Canario, such as the Presa Espanol.
Its numbers have dropped over the years, but in the 1970s, reputable breeders bred Presa Canarios, a courageous, territorial dog.
Because of its aggressive tendencies, the dog has been banned from quite a few countries. It is found in the USA but not recognized by the American Kennel Club.
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.
The Presa Canario is a large Molosser-type dog breed originally bred for working livestock.He stands at between 56 to 65cm in height and weighs between 38 and 60kg. He has a thick, muscular body with a black mask over the broad head.
The ears were always cropped which just added to his aggressive appearance. When left they are high set and floppy, being of medium length. The coat is short and coarse and he is a low shedder. The coat comes in colors such as fawn, tan, or brindle.
Strong willed, confident and determined, the Presa Canario may well have an intimidating look.He looks both powerful and even a bit aggressive, but with training and socialization, the highly intelligent Presa Canario is actually a calm, docile dog, totally loyal and loving with his human family.
These dogs are suspicious of strangers and this makes them excellent watchdogs. For new dog owners, the Presa Canario isn’t a good first choice as he is strong-willed and can be aggressive when in the wrong hands. There are however, always exceptions, but he isn't considered to be a good choice of dog when there are children in the home.
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.
The Presa Canario is a formidable looking dog and has received quite a lot of negative media attention for being aggressive and dangerous. And yet non-aggressive owners who have brought the dog up properly tell of how well mannered and calm their dogs are.
The dog is confident and powerful and can be loyal and loving while also being well adjusted. Just like children are the fruit of their parents upbringing, so dogs turn out much the same as the kind of owners that reared them, and in the right hands, this big dog can be loyal quiet, loving and trustworthy.
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.
These are large dogs so they are susceptible to hip- or joint dysplasia and canine leishmaniasis.
This is a skeletal condition, found more often in large dogs. The ball and socket don’t fit properly, grinding as opposed to sliding smoothly. This eventually leads to loss of function of the joint.
There are a few factors that lead to the development of hip dysplasia in dogs, but it is also hereditary. That is why it is so important to provide your dog with the correct nutrition – one that is specially formulated for large breeds.
This is a deadly disease caused by a protozoan parasite found in dogs, mostly in rural areas, and in quite a few areas of the world.
The parasite is transmitted by a sand fly. The clinical signs of dogs with this disease include weakness, fever, swollen lymph nodes, anorexia, weight loss and diarrhea with blood in the stools.
Treatment will require the administration of a special drug. Prognosis for a pet diagnosed with Leishmaniasis is unfortunately not very hopeful.
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.
As previously mentioned the American Hairless Terrier has skin health issues and is also prone to hip dysplasia.
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.
The Presa Canario will require being brushed twice a week to rid him of loose hair although he isn’t a heavy shedder.
Keep his nails trimmed.
Check inside his ears for signs of redness and the possibility of an ear infection.
When you brush him, check him over for any unusual lumps.
Make sure the dog is neutered or spayed if you don’t want puppies.
Get your vet to the vet if he shows signs of illness.
Make sure his vaccines are up to date to prevent some deadly canine diseases.
Ensure he has a nice comfortable, dry, warm place to sleep.
Ensure he has a top quality diet to enhance longevity and health. Commercially manufactured dog foods are a convenient means to feed your pet, and there are some excellent brands. Avoid the ones with low quality ingredients that don’t have the right balances of vitamins and minerals.
High quality dry kibble can become exciting when you add in some home-made food. Dogs thrive on simplicity, so boiled chicken, sweet potatoes, brown rice or pasta, carrots and spinach will be 100% sufficient for him. Chop this food up and add it into the dry kibble twice a week as a tasty treat.
Also, your pet will thrive on a bit of raw meat added in from time to time. Make sure he is never without a constant supply of fresh, cool water.
Make sure that your large pet gets a good quota of daily exercise outdoors. Lots of hectic ball- and rope games will keep him happy and keep him slim. Take him for a walk every day.
