Long Haired Chihuahua 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 short haired Chihuahua is such a recognizable dog breed, probably because of his tiny size, but did you know that you also get a long haired variety?

Looking quite a bit like a Pomeranian, the only difference between the two types of Chihuahua is the length of the coat.

This small dog dates back to Mayan times and while it may well have originated in Mexico, its popularity saw it becoming a sought after pet in other countries too.

To get the long haired Chihuahua, breeding programs were established and the short-haired variety was mated with other long haired toy sized dogs such as the Pomeranian and the Yorkshire Terrier.

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.

Your long haired Chihuahua will have a coat that is soft and slightly wavy. He weighs between 1 and 3kg and stands at about 15 – 23cm. He generally sheds throughout the year with a couple of heavier shedding periods during the year.

Don’t be fooled by the long, thick hair on the long haired Chihuahua as it doesn’t protect him from the cold – in fact he doesn’t tolerate the cold well at all, and is essentially an indoor dog. The ears are erect and feathery and the tail is full and plumed, lying over the back. He has a ruff on the neck, which is often described as a mane.

Temperament:

Chihuahuas are such bright-as-a-button little dogs and they’re intelligent too.

It’s difficult to say how a dog’s temperament will turn out, because breed, lifestyle and the type of owners can all make a dog a certain way.

Socialization and training can sometimes help with a dog that has bad genes. There are some people who say the Long haired Chihuahua is a nasty, aggressive little dog who’ll easily give you a nip but they’ve got a good reputation with many other dog lovers.

They love their own human family but may take quite a while to chill towards other people and other dogs too. They’re more ‘birds of a feather flock together’ type of dogs, preferring to get on with other Chihuahua dogs.

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 Chihuahua is such a feisty, courageous, confident little dog who also believes that he is part- lion. He is loving, sweet and gentle and just loves being picked up and petted non-stop. He looks up at you, moving his front paws up and down to tell you that he wants to be picked up.

He is in 7th heaven when he can be cuddled up in your lap. You just have to teach your children to be very careful with him and not enter into games with him that are too rough and tumble. Tiny he may be but he makes a great watchdog too, barking and alerting you to strangers.

His small size makes him perfect for life in the city or in the countryside. Just be careful when in the countryside lest an Eagle or Owl scoop him up and carry him off to some faraway nest.

He doesn’t need a great deal of exercise either and you can actually keep him happily busy with some games indoors. He’ll always welcome walks with you though.

This small dog is full of life and confidence and he is ready to be your constant, loving companion.

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.

With good care, you’ll have your long haired Chihuahua with you for a long time – 15 years and longer.

Parasites:

You Chihuahua will need to be vaccinated when he is a puppy and even when he is an adult, although less often. These vaccines will protect your Chihuahua from the likes of parvo, distemper and rabies. Have your chihuahua spayed or neutered.

There are so many puppies in the world who can’t find homes. Desexing your Chihuahua is a responsible way to ensure your pet doesn’t have puppies. Spaying and neutering can actually be beneficial for your dog’s health.

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.
