Dog breed introduction

What is a terrier

This type of dog breed is good at digging crypts and hunting small animals such as badgers, foxes, and hares that live in the soil or burrows. They are generally small in size, which is also in line with this demand. Most terriers originated in England.

Many modern terriers have been crossed with other dog breeds due to certain needs. Formed a lot of playful terriers. Although modern people have very little demand for the original hunting purpose of terriers, to show respect and remembrance for the contribution of terriers in human history, people want to keep some of the traditional primitive and pure terriers. The predecessor of the Hairless Terrier, the Rat Terrier, is one of the traditional terriers.

Terriers have a unique mental temperament, even if they know that they can’t win under objective conditions. But the fearless spirit that can still move forward bravely. This temperament touched most of the lovers who love this breed of dog. Known as the “terrier spirit”

But terriers are not bloody spokespersons. Instead, most purebred terriers have great restraint. In the Middle Ages, complete fox skins were very popular among the nobles. Therefore, terriers are strictly required to be regulated in the process of being domesticated. A good terrier would rather be attacked or even lose its life than hurt the skin of a fox or accidentally injure humans. This gene of subconscious existence has been deliberately retained to this day.

Hairless Terrier breed history

The American Hairless Terrier (officially known as the American Hairless Terrier) is the only hairless dog breed produced in the United States. It is a natural variant of the rat terrier.

The large rat terriers have been around since the beginning of the 18th century. Over time they were bred into one of many small dog breeds in the UK to eliminate the rats that spread diseases and eat the national food. Originally called First (translated as puppy) as proof of their lively temperament. These rat terriers are amazing rat hunters. They were taken to the farm and said that they had caught 2500 rats in a day in a barn flooded with rats) and a famous rodent infestation. People will place bets on their favorite rat terriers, guessing how many mice they can kill.

At the end of the 18th century, the First was brought to the American countryside by British miners. Here, they seek a new life. It was here that Fest became a new breed after crossing with the Fox Terrier. It is said that President Roosevelt loved his hybrid version of Fest called “Jump” very much, and he coined the name Rat Terrier.

Time flies by 70 years, from the time of Roosevelt to 1972. At this time, in Trout Town, Louisiana, a strange thing happened. A hairless rat terrier pup was born in a litter of medium-sized rat terriers that usually have hair. (But it’s worth noting that hairless pups are born with lanugo, and they don’t gradually shed their lanugo until they are a few weeks old. A couple named Edwin and Willie got hairless rat terriers And named Josephine. She was carefully nurtured and gave birth to a hairless girl named “Gypsy.” Eight years later, Josephine gave birth to several pups with fur and a pair of Hairless siblings, Jemima (mother) and Snoopy (male). In 1983, Snoopy was used to mate with his sisters and bred several hairless offspring. Since then, one new breed, the American Hairless Terrier, was born.

Edwin Scott continued their breeding program, kept careful records, and established the first club specifically for their new breed. The AKC Kennel Club (American Hairless Terrier Club) of this breed was established in 2009. This variety was fully recognized by AKC in 2016.

When the indoor temperature is lower than 17 degrees Celsius, there will generally be a reluctance to exercise and increased food intake. But for a period of time to go out, they can accept lower temperatures.

The highest temperature that the American Hairless Terrier (officially known as the American Hairless Terrier) can accept is the same as that of other dog breeds. Under normal circumstances, dehydration is the greatest hazard to it caused by high-temperature environments.

8. AHT is the first hairless dog breed that originated in the United States.

9. They will not infect and shed fleas and other parasites, but they will shed dander.
