Identification of American Hairless Terrier

 1. The American Hairless Terrier stands between 12 to 16 inches at the shoulder, and comes in both coated and hairless varieties. The hairless variety might have eyebrows and whiskers, while the coated has a short, shiny coat. The skin of the hairless is smooth and warm to the touch.

2. Hairlessness American Hairless Terrier type is an inherited trait specific for this breed and caused by a breed specific mutation. Generally, worldwide recognized hairless dog breeds are the Chinese crested dog, the Mexican hairless dog and the Peruvian hairless dog. Mexican hairless dog is also known as the Xoloitzcuintli, and it was considered sacred by the Aztecs. In these breeds the hairless phenotype is classified as canine ectodermal dysplasia (CED) and is caused by the same mutation. Unlike in other hairless dog breeds, hairlessness in American Hairless Terrier is a recessive mutation and is not lethal when animal is homozygote for the mutation. Also, AHT are generally healthy dogs born with fuzzy coat which is lost within first few months after birth.

3. Hairlessness American Hairless Terrier type is caused by a mutation of SGK3 gene located on canine chromosome 29. The disorder is inherited in an autosomal recessive pattern of inheritance, which means two causative genes need to be present in order for the puppy to be hairless. Coated parents of a hairless dog are obligate heterozygotes and therefore carry one mutant allele. Heterozygotes are carriers and display no hairlessness. At conception, each cub has a 25% chance of being hairless, a 50% chance of being an asymptomatic carrier, and a 25% chance of being coated.

4. The American Hairless Terrier is a feist breed from the United States. They are descendants from the Rat Terrier native to Louisiana. With hairless and coated varieties, the hairless has eyebrows and whiskers, and the skin is warm and smooth to the touch. The coated has a short and shiny coat. Both have a broad, wedge-shaped head, erect, V-shaped ears, and round expressive eyes. The American Hairless Terrier is known to be a smart, inquisitive, and playful dog that is hypoallergenic, great for those who suffer from allergies.

5. American Hairless Terriers have a withers height between 12”-16” (30-41 cm) and a typical weight in the range of 7-16 lb (3-7 kg). The American Hairless Terrier has an overall body length of roughly 18”-23” (46-58 cm), standing height between 17”-22” (43-56 cm), and a typical lifespan of 12-16 years.

6. American Hairless Terriers are interesting from a genetic point of view. While there are a few other hairless or nearly hairless breeds around the world, the gene that most often produces dogs without any fur are dominant genes. These dominant genes often have collateral effects on the dog’s health, such as genetically absent adult teeth. On the other hand, the gene that makes American Hairless Terriers totally bald is a recessive gene, so they are not susceptible to some of the health issues that may crop up in other hairless dogs.

7. Despite the myth that hairless dogs are hypoallergenic, American Hairless Terriers are not necessarily a good choice for those who suffer severe dog allergies, as many people are allergic to the dander and not the dog’s fur. There are also special grooming and health considerations to keep in mind when deciding to add a hairless dog to the family: they are sensitive to the elements and require skin care, just as other breeds require grooming.

8. Though it is descended from good hunters, the lack of a coat actually makes the American Hairless Terrier unsuited for hunting. This is because the lack of fur means it has little protection against branches and foliage, and it also requires sunscreen if it were to be left out in the sun for a significant amount of time.

9. Like most small dogs that think they are bigger dogs, the American Hairless Terrier can get very upset if it feels its territory is being encroached upon. The breed is very territorial and forms an attachment both to its home and the surrounding area, and the family that adopts it. As such, they do make an excellent watch dog, and due to their hunting instincts, they like to chase other small animals off of what it considers its property.

10. While many dogs both large and small can swim rather well, the American Hairless Terrier cannot be counted among them. However, that doesn’t mean they won’t try to swim, and so if your yard contains a pool or there is a lake nearby, you will want to exercise caution and keep a watchful eye on your furry friend. Putting a fence around a pool is a good call, and keeping the dog on a leash when walking near lakes or other bodies of water is recommended. The American Hairless Terrier is a quick dog, and can get into a body of water within seconds if you aren’t alert and monitoring the dog closely.
