Mexican Hairless 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.

Who can believe that the origin of these dogs which hail from Mexico, goes back more than 3,500 years?

Known as the Xoloitzcuintli dog or Xolo for short, they comes in different sizes – toy-, miniature and standard which means there are different sizes. Both coated- and hairless dogs can be found in the same litter.

There was a time when the dog nearly became extinct buts its numbers have recovered. This is no doubt because there was a time when the natives ate the dog’s flesh.

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 Mexican Hairless is truly an ancient dog breed of the Americans. He stands at 35 – 58cm if he is the standard variety whereas the miniature will stand at up to 35cm. Weight can vary too, but with the standard variety, you're talking about 16 to 22kg.

It has faced times of nearly being extinct but it’s numbers have recovered, and the dog is often sought after for those who suffer with dog-hair allergies. You could say that this dog’s most notable characteristic is its lack of hair and the soft skin.

Some of them have small tufts of hair on the hair, mostly around the top of the head. The skin can be various shades of gray to bronze and a yellowish color too. His body is slightly longer than its height and he is slim and well muscled. The tail is long and thin and is sometimes carried high. You can expect 2 – 5 puppies from these dogs.

Temperament:

Anyone acquiring a Xolo will discover that this is an intelligent dog breed and that just like with other dogs, you’ll be able to have him trained and socialized easily. Then he is obedient and a pleasure to have around.

He is active too and will require games with balls and ropes as well as a daily walk. The Xoloitzcuintli is noted for its calm demeanor. The puppies are a lot noisier than the adults and very energetic and this continues till they are about 2 years of age when they are considered to be adult.

Well raised Xolos form strong bonds with their human family, becoming loyal and devoted.

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 Xolo is one of those dogs who don’t get ill easily. He is also intelligent and fairly easy to train. Add to that the fact that he is also a low maintenance dog as he doesn’t have a coat that needs brushing and grooming.

Give your Xolo lots of attention because in exchange for the good care you give him, you’re going to get a loyal, devoted pet who loves to be with you constantly.

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.

The Xoloitzcuintli is a hardy dog in terms of health and can live to a ripe old age in dog years – some have been known to reach 18, 19 and 20 years of age. Without a coat, this dog is susceptible to sunburn so care must be taken when outdoors.

Hairless dogs tend to battle with skin problems such as pimples. Skin allergies can cause itching and scratching and these can lead to bacterial infections. It is interesting to note that the genes that bring about hairlessness also produce troublesome teeth, so that dental disease is quite rife with these dogs.

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.

You’ve got to remember with this dog breed that he doesn’t have a coat so he can burn easily when out in the sun. If you know you’ll be in the sun for long, you’ll have to apply special sunscreen.

You can wipe down your Xolo or bath him from time to time, though not to often so as to strip the natural oils from the dog’s body. The nails will need to be trimmed regularly, as long nails can be a danger as they can hook on things and cause pain and bleeding.

Provide your hairless pet with a nice, soft bed to lie on.

Take him to the vet when he appears to be ill and see that you get his vaccinations done to prevent deadly illnesses such as rabies and parvo.

Check his eyes and ears for infections.

Brush his teeth to remove plaque. Never use human toothpaste. Take a look at the different canine toothpastes available.

Never leave your pet in a hot car with no windows open.

Provide your Xoloitzcuintli dog with high quality dog food so as to enhance health and longevity. Keep food simple for your pet to avoid digestive problems. Boiled chicken, brown rice or pasta and cooked potato, carrots and spinach can be chopped up and added to his dry kibble from time to time. Also a little bit of raw meat added in occasionally can also be excellent. Avoid feeding your pet foods such as onions, avocados, nuts, chocolate, coffee and raisins.

Make sure this dog has access to cool, fresh water night and day.
