American Hairless Terrier

The American Hairless Terrier is an American dog breed that has originated in the United States of America and it is their only native, hairless breed. These dogs are lively and active family companions that are a great choice for families that love dogs but have allergy sufferers at home. These dogs are also sometimes called hairless Rat Terriers or people refer to them as AHT.

This active, small dog breed is a typical terrier - alert, curious, and fairly intelligent. It is not the oldest breed in the world, in fact, the first American Hairless Terrier was born in 1972 when a Rat Terrier birthed a dog whose birth hair fell off in a couple of weeks. Their owners decided to further breed that hairless dog (which they called Josephine) and 11 years later, the breed got stable breeding bloodlines.

The American Hairless Terrier is considered to be a terrier of medium to small size with an active temperament. These dogs are well-muscled and relatively strong compared to their size. As their name suggests, they have no hair and that makes them unfit for most of the hunting tasks their ancestors did.

The American Hairless Terrier has a rectangular built with a 10:9 ratio in favor of its length. Their noses should always be solid-colored and their eyes should be round and medium-sized. Their ears are V-shaped and set on the outer part of their head- on the very edge of their skull. They can have both erect, buttoned, or tipped ears, however, the erect ears are favored in the show ring.

American Hairless Terrier temperament

The American Hairless Terrier is your typical terrier with an alert, active, and curious temperament. They are descendants of the Rat Terriers but since they are hairless, they are unfit for most hunting jobs. They have inherited their high prey drive and natural hunting instinct nonetheless. They will most likely view smaller animals like gerbils, rabbits, or guinea pigs as prey and should never be fully trusted around them.

These dogs thrive on attention and affection. They are a great fit for active, large families where there is at least one person that the American Hairless Terrier can be with. They hate being left alone for long periods of time and will not hesitate to tell you how they feel about that. They are vocal and express their feelings through barking so it is a good idea to teach your American Hairless Terrier to stop barking on demand.

American Hairless Terrier training and socialization

The training and socialization of an American Hairless Terrier should be high on your priority list as well as a big part of their lives. All dog breeds require that you invest time in their development and learning and this breed is no different.

You should start training your American Hairless Terrier as soon as it arrives at your home and make sure that they know the rules you have set for them. They are fairly intelligent and will try to test your boundaries and see if you are willing to bend the rules for them. Be consistent and gentle, involve loads of food and treats in their training, and pretty soon you will notice great results.

The American Hairless Terrier is a terrier, and as a member of the terrier family of dog breeds, should be properly socialized. Terriers, in general, can be feisty and will not back down from any fight. Make sure your dog knows how to properly behave in all social situations and help them by exposing them early to different sights, sounds, situations, people, and other dogs. That way your dog can learn social rules and you can teach them proper behavior.
