A Regal History: Pugs as Prized Pets in Imperial China

To understand how the curly tail came to be, we need to go back—way back—to the pug‘s beginnings. Although their exact origins are uncertain, most historians agree that pugs descended from the "lo-sze," short-nosed dogs who were prized pets amongst Chinese emperors during the Han dynasty over 2,000 years ago.

These small, wrinkly flat-faced dogs served as companions, lapdogs and even guards in the imperial palaces and courts of China for centuries. They were considered a symbol of wealth and prestige. According to Chinese legend, emperors would give pugs to officials as gifts of honor.

Early Chinese depictions and figurines of pugs from this period show dogs with wrinkly faces, round heads, short legs and—you guessed it—curled tails that arched over their backs. This suggests that the curly tail was already an established trait hundreds of years ago when pugs first emerged as a distinct breed. But why?

Bred to Perfection: 3 Theories on the Pug‘s Purposefully Curled Tail

While we may never know for certain, there are a few intriguing theories as to why ancient breeders may have selectively bred pugs to have tightly curled tails:

1. A Lucky Twist of Fate

In Chinese culture, curly tails on dogs were seen as a sign of good luck and nobility. One theory is that breeders purposefully selected and reproduced pugs with the curliest tails in order to appeal to the superstitions of royal families. The more tightly wound the curl, the more luck and prestige the dog would bring.

2. The Ultimate Lap Warmer

Since pugs served as lapdogs to emperors, another possibility is that the curled tail was bred as a functional trait to help keep the pug‘s face warm. When a pug curls up in a ball on your lap, its tail curves around to cover its nose like a furry scarf, providing extra insulation.

3. A Genetic Glitch

In the bulldog and some other short-faced breeds, a curly tail can be a sign of a genetic deformity linked to their compressed spinal column. Since pugs and bulldogs share some common ancestors, it‘s possible that the pug‘s curl is also associated with an inherited malformation. However, unlike the bulldog, a curled tail thankfully does not seem to negatively impact the pug‘s health in most cases.

Regardless of the original reasoning, the curled tail soon became a defining characteristic of the pug breed. As pugs spread to Europe in the 1500s and later to the United States, the coiled tail was here to stay. The American Kennel Club even made it part of the official pug breed standard, describing it as "curled as tightly as possible over the hip."

The Perfectly Imperfect Pug Tail

Now that we know some of the history and theories behind the curl, let‘s take a closer look (or should I say, a closer curl) at what makes the pug‘s tail so unique.

Anatomically, a pug‘s tail is quite short, usually only 4-7 inches in length. While most dogs have 20-23 vertebrae in their tails, pugs typically only have 11-13. The curl is caused by wedge-shaped and fused vertebrae at the end of the tailbone.

Unlike the long, flowing tails of breeds like labs or huskies that serve as rudders for balance while running, the pug‘s stumpy cinnamon bun of a tail has little impact on their locomotion. In fact, their tail is so tightly wound that some pugs have trouble lifting or wagging it.

The shape of the curl itself can also vary quite a bit from pug to pug. The ideal show-quality pug has a "double curl" where the tail loops around twice, but single curls are much more common. Some pugs have loose curls that flop to one side while others have tails that curve upwards like a fish hook. Occasionally, a pug may even be born with a straight tail, but this is considered a fault in the show ring.

When a Curly Tail Becomes a Health Concern

As endearing as those coiled tails are, they can sometimes pose health problems for our pug pals. Because the curl is so tight and the skin folds over on itself, the area underneath the tail can be prone to infection if not kept clean and dry. Owners need to regularly wipe and examine the skin to prevent irritation, sores or even fly strike in severe cases.

Some pugs with very tightly curled tails may also be more prone to anal gland issues or bowel problems if the tail is putting pressure on the rectum. Rarely, the curl may be so kinked that it causes pain or neurological issues and requires surgical correction to amputate the tail. However, this is not common in pugs.

It‘s important for pug owners to pay attention to any changes in their dog‘s toileting habits or tail carriage and consult with a vet if they suspect a problem. Generally though, that adorable curl is harmless.

Caring for Your Pug‘s Precious Pigtail

To keep your pug‘s tail in tip top shape, be sure to:

• Gently clean underneath and around the tail with a damp cloth or baby wipe at least weekly. Dry thoroughly.
• Brush through the fur on the tail regularly to prevent mats and tangles.
• Keep an eye out for any redness, flaking, odor or discharge and contact your vet if you notice irritation.
• Support your pug‘s backend when holding them to avoid putting stress on the tail.
• Let your vet examine the tail at annual check-ups to look for any abnormalities.

With a little extra TLC for that curly-Q, your pug will be wagging happily for years to come!

Other Breeds Born with a Twist

Think pugs cornered the market on curls? Not quite! Several other breeds are also known for their uniquely curved tails, including:

• Akitas
• Basenjis
• Chow Chows
• Shiba Inus
• Icelandic Sheepdogs
• Norwegian Buhunds
• Tibetan Spaniels
• Finnish Spitz

Each of these breeds has a curve or loop to their tail carriage, but none curl as tightly as the pug. The basenji, for example, has a single loose curl while the akita‘s tail arches over its back like a sickle.

Interestingly, many of these curly-tailed breeds also originate from China or share ancient Asian heritage with the pug. Perhaps there was something about the curved tail that appealed to Eastern dog breeders and owners throughout history.

Frequently Asked Questions About Pugs

As a vet, I hear a lot of questions from prospective pug owners. Let‘s address some of the most common ones:

Q: Do pugs make good family pets?
A: Pugs can be wonderful companions for families with kids. They are generally playful, affectionate, and good-natured. However, they can be prone to breathing issues and overheating, so supervise them around young children and don‘t let them overexert themselves.

Q: How much do pugs typically cost?
A: The price for a pug puppy can vary depending on location, pedigree, and other factors but usually ranges from $600-$2000. Adoption fees for older pugs may be $200-$500. Remember that pugs tend to have higher vet bills over their lifetime compared to other breeds.

Q: Are pugs hard to train?
A: Pugs can be a bit stubborn and hard to motivate, but they are usually eager to please. The key is finding a reward that really excites them (usually food) and keeping training sessions short and fun. With patience and consistency, pugs can learn basic commands and tricks. House training can be a challenge though.

Q: Do pugs need a lot of exercise?
A: Pugs have relatively low exercise needs compared to many dogs. A couple short walks per day and some playtime is usually sufficient. They are prone to overheating so avoid long walks in hot weather and always bring water. Some pugs love to hike and be active while others are content being couch potatoes.

Q: What health problems are pugs prone to?
A: Some of the most common health issues in pugs include breathing difficulties (due to their short snouts), eye problems like corneal ulcers, allergies, skin fold infections, luxating patellas, and spinal issues like hemivertebrae. Obesity is also very common and damaging for the breed.

Q: What is the average lifespan of a pug?
A: Pugs live 12-15 years on average. This is fairly typical for a dog their size. However, many of the health conditions they are prone to can shorten their lifespan, which is why preventative vet care, a healthy diet, and an active lifestyle are so important for pugs.

The Tale of the Curly Tail

Isn‘t it fascinating how much history and intrigue can be wrapped up in something as silly as a dog‘s tail? The pug‘s curly tail has been a source of joy, luck, warmth, and maybe even a few head scratches for centuries.

The next time you see a pug, take a moment to appreciate that tightly wound tail and all the breeding and biology behind it. Of course, your pug would probably just prefer if you gave them a treat instead.
