쉐어피스는 왜 이렇게 주름이 많나요?

Shar Peis distinguishes themselves from other dog breeds with their unique skin wrinkles, which add to their beauty and uniqueness. Dog lovers everywhere have been enthralled with these wrinkles, raising questions about their origin and significance. But do you ever wondered why are Shar Peis so wrinkly? We will go into the fascinating world of Shar Pei wrinkles in this article, looking at their biological importance and possible advantages for these lovable companions.

History

Although domestication of dogs dates back at least 10,000 years, the majority of the current breeds have only recently emerged. Selective breeding has always required the selection of genes and the manipulation of their expression, even if genetics was unknown in the early days.

Compared to a study of humans, it is simpler to determine which genes result in specific phenotypes (physical qualities) in dog breeds due to their vast genetic diversity. Examining the genetic alterations in dogs that give rise to their various sizes, shapes, and temperaments may also uncover genetic alterations that may have resulted in diseases unique to a particular breed and distinct behavioral patterns.

The Genetics of Wrinkles

Genetic abnormalities affecting the formation of collagen, a protein responsible for skin elasticity, cause Sharp-Peis’ wrinkles. In particular, a mutation in the HAS2 gene results in a reduction in collagen synthesis, which causes the skin to wrinkle and fold. The folds surrounding the breed’s face, neck, and torso, as well as its loose, wrinkled skin, result from these mutations.

The unique wrinkly skin of Shar Peis is strongly associated with certain hereditary characteristics, with extracellular matrix development and skin structure genes playing a major role. The two main components of this genetic composition are collagen and HAS2 (Hyaluronan Synthase 2).

1. Hyaluronan Synthase 2 (HAS2)

Hyaluronic Acid (HA) Synthesis: The enzyme Hyaluronan Synthase 2 is encoded by the HAS2 gene. The production of hyaluronic acid (HA), a significant component of the extracellular matrix, is greatly aided by this enzyme.

Hyaluronic acid plays a crucial role in maintaining the structure and integrity of the extracellular matrix, which is necessary for the growth and upkeep of skin tissues. In Shar Peis, hyaluronic acid distribution is probably influenced by HAS2 activity.

Alterations in the synthesis or distribution of hyaluronic acid may result from variants or mutations in the HAS2 gene. This can therefore have an impact on the skin’s pliability and elasticity, which can add to the breed’s characteristic wrinkles.

2. Collagen

Collagen is a structural protein that gives connective tissues, such as the skin, their strength and suppleness. There are several varieties of collagen, and changes in its synthesis can affect the properties of the skin.

The tensile strength and resilience of the skin can be influenced by genes linked to the structure and production of collagen. The loose and folded skin appearance of Shar Peis may be attributed to certain hereditary variables connected to collagen.

Variations in the genetic makeup of collagen-related genes may result in modifications to the structure or organization of collagen fibers in the skin. This may lead to the formation of wrinkles, which gives the Shar Pei its characteristic wrinkled look.

Variation in Wrinkles

It’s fascinating to see that the number of wrinkles varies amongst Shar-Peis. Some might have less wrinkles, while others might have wrinkles all over them. A mix of selective breeding and genetics is responsible for this diversity. Breeders have enhanced this unique characteristic in the breed throughout time by selecting dogs for breeding who have more noticeable wrinkles.

Reasons for Shar Pies wrinkled skin

Why Shar Pei has wrinkles is the subject of several theories. One explanation is that these dogs’ wrinkles helped them blend in with their surroundings when they were hunting.

Prey would find it more difficult to identify the dog with its wrinkles since they would break up their outline.

Another explanation is that during their struggle, Shar Pei’s eyes were shielded from dirt and debris by the wrinkles. The skin surrounding the eyes would stay cleaner and clear of debris if it were wrinkled. Whatever the cause of their wrinkly skin, it’s undoubtedly one among the characteristics that set the Shar Pei apart!

Problems caused by the Shar Pei’s wrinkles

The unique wrinkles of the Shar Pei breed define it, however owners should be warned that these wrinkles can also cause certain issues. The following are some possible problems that can arise from Shar Pei wrinkles:

Fungal Infections

The deep furrows may produce a humid, heated atmosphere that encourages the growth of fungi and consequent infections.

Bacterial infections

Because wrinkles can hold on to moisture and debris, they can act as a haven for bacteria that can lead to skin infections.

알레르기

Due of the wrinkles’ ability to trap allergens, Shar Peis may be more sensitive to skin allergies.

Challenges with Cleaning

It could be difficult to keep the wrinkles neat. The folds may collect moisture, dirt, and debris, therefore, routine cleaning is necessary to avoid infections.

Joint Problems

A disease known as “Shar Pei fever” or Familial Shar Pei Fever (FSF) can strike some Shar Peis and result in joint pain and edema. Joint issues are more prevalent in the breed, despite having no clear connection to wrinkles.

Breathing Problems

As it can affect the air channels, excessive wrinkling around the head and neck may be a factor in respiratory problems.

The characteristic folds around the head and neck of Shar Peis are linked to breathing problems. Although not all Shar Peis have respiratory problems, the breed’s distinctive anatomy may make some breathing difficulties more common.

Airway and nasal blockage

Occasionally, nasal blockage might be somewhat caused by the skin folds surrounding the nose and snout. The creases may partially obstruct the airway, making breathing harder to do.

Grooming Challenges

Shar Peis need to be groomed on a regular basis to avoid skin issues. This includes washing and drying their wrinkles. This breed might not be appropriate for people who don’t want to devote time to grooming.

Heat and Retention of Moisture

Shar Peis are more prone to heat-related problems because of the wrinkling, which can trap heat and moisture.

Entropion

When an eyelid entropion occurs, the lashes rub against the eye as the eyelid turns inward. This may cause the cornea to become irritated, red, or even swollen.

Ectropion

The disorder known as ectropion causes the eyelid to turn outward and away from the eye. This may result in dryness and irritation of the eye. Infection risk may also rise as a result.

Make sure you take your dog to the doctor as soon as you notice any changes in their eyes. They are able to identify and address any potential issues.

Shar Pei dogs are undoubtedly unique, in part because of their extremely wrinkled skin. Even if this could be one of their most distinctive characteristics, it’s crucial to understand the health issues that are associated with these wrinkles.

Maintenance and Care for wrinkles

Shar-Peis need particular attention to maintain their health and comfort, even if their wrinkles are an essential part of who they are. The folds are prone to skin infections because they can collect moisture, debris, and filth. To avoid skin problems, these regions must be cleaned and dried on a regular basis. Furthermore, keeping up good grooming and hygiene habits will benefit your Shar-Pei’s general health.

As Shar Peis tend to retain moisture and debris in the folds of their skin, regular cleaning is essential for those with wrinkles. Deep wrinkles can harbor germs, fungi, and dirt, which can cause irritations and infections of the skin. In order to clear dirt and delay the beginning of skin-related problems, owners should implement a regular cleaning schedule. Maintaining the health of Shar Peis’s skin requires using a gentle cleanser that has been approved by the vet and making sure the pet is completely dried after cleaning. Owners can keep their Shar Peis comfortable and healthy by minimizing the risk of infections by regular cleaning as part of their grooming routine.

Preventive Steps to Prevent Health Problems

Owners of Shar Peis can take a few preventive steps in addition to routine cleaning to avoid health problems related to wrinkles. Providing a nutrient-dense, well-balanced diet improves skin health overall and lowers the risk of skin sensitivities and irritations. Maintaining a healthy weight is crucial because being overweight might worsen skin conditions.

Frequent exercise promotes good skin conditions and helps to increase circulation. Owners should also be aware of environmental elements that can affect the skin, such as avoiding exposure to extremely high or low temperatures. Owners can limit the likelihood of health issues related to wrinkles in their Shar Peis and enhance their overall well-being by taking proactive measures to address these factors.

Does Shar Peis Lose Their Wrinkles?

When Shar Peis get older, their wrinkles tend to become less noticeable. The skin of Shar Pei puppies is usually more loose and wrinkled; as they get older, the skin becomes tighter and the wrinkles less noticeable. But each dog is different when it comes to how much their wrinkles disappear.

Not to mention that even though wrinkles could get smaller as they age, Shar Peis will always have some wrinkles in some form or another. Frequent maintenance, such as good grooming and cleansing of the skin folds, can help preserve the health of the dog’s skin and lower the likelihood of wrinkle-related skin issues. In addition, a Shar Pei’s age-related wrinkle development can be influenced by hereditary and general health variables.
