Should I Buy A Puppy With An Underbite? Read This First

Are you considering adding a furry friend to your family, but have concerns about whether or not to buy a puppy with an underbite? In this comprehensive guide, we will explore the topic of underbites in dogs. Helping you make an informed decision when choosing the perfect canine companion.

It is essential to understand the implications of buying a puppy with an underbite. As it can impact their health, well-being, and overall care. By the end of this article, you’ll have a better grasp of the factors to consider when deciding if a dog with an underbite is the right fit for your family.

So, let’s dive in and learn all there is to know about puppy underbites!

What is an Underbite?

An underbite, also known as mandibular prognathism or brachygnathism, is a dental condition in which the lower jaw protrudes beyond the upper jaw. (1)

This misalignment of the teeth and jaw can cause the bottom teeth to sit in front of the top teeth when the mouth is closed.

Underbites are relatively common in dogs, and the severity can range from mild to more pronounced cases.

How Does an Underbite Occur in Dogs?

Underbites occur due to a combination of genetic factors and developmental influences during a dog’s growth. In some cases, the lower jaw grows too long, while in others, the upper jaw may be too short.

The misalignment can also be a result of uneven growth rates between the upper and lower jaws. While certain dog breeds are predisposed to developing underbites, they can also occur in mixed breed dogs.

Common Health Issues Associated with Underbites

While some dogs with underbites may not experience any significant health problems, others may be more prone to various dental and oral issues. These can include:

  1. Tooth crowding: The misalignment of the jaws can cause teeth to overlap or become crowded, making it difficult to maintain proper dental hygiene and increasing the risk of tooth decay and gum disease.
  2. Abnormal tooth wear: Uneven pressure on the teeth can result in accelerated wear and tear, which may eventually lead to tooth loss or damage.
  3. Difficulty eating: In severe cases, dogs with underbites may struggle to pick up or chew food properly, potentially affecting their nutrition and overall health.
  4. Breathing difficulties: Some dogs with pronounced underbites may experience restricted airflow due to the altered position of their jaws, leading to snoring, sleep apnea, or other respiratory issues.
  5. Pain and discomfort: The misalignment of the jaws can cause pressure on certain parts of the mouth, leading to discomfort or even pain.

Impact of Underbites on a Dog’s Quality of Life

For many dogs with underbites, the condition does not significantly impact their quality of life. They may be able to eat, play, and interact with others without any noticeable issues.

However, in more severe cases, the problems mentioned above can affect the dog’s overall well-being and happiness.

It is essential to monitor your dog’s dental health and consult a veterinarian if you notice any signs of pain, discomfort, or difficulty eating. Early intervention can help to manage potential health issues and improve your dog’s quality of life.

The Role of Genetics in Underbites

Should I buy a puppy with an underbite

Genetics play a significant role in the development of underbites in dogs. The condition often runs in families, and certain breeds have a higher prevalence of underbites due to their unique skull shapes and jaw structures.

Selective breeding for specific physical traits, such as a shorter snout or a “squished” face, has contributed to the increased incidence of underbites in some breeds.

The Likelihood of Inheriting an Underbite from Parents

If both parents of a puppy have an underbite, the likelihood of their offspring inheriting the condition is considerably higher. However, it is important to note that inheritance is not guaranteed, as other genetic factors and developmental influences may come into play.

In mixed breed dogs, it can be more challenging to predict the chances of inheriting an underbite due to the potential for a greater variety of genetic traits.

To better understand the potential risk of underbite inheritance, it is advisable to consult with a veterinarian or a canine geneticist.

Breeds Prone To Developing Underbites

While any dog can potentially develop an underbite, certain breeds are more prone to this dental condition due to their genetic makeup and physical characteristics. Some of these breeds include:

  1. Boxers
  2. Bulldogs (English, French, and American)
  3. Pugs
  4. Shih Tzus
  5. Lhasa Apsos
  6. Pekingese
  7. Boston Terriers
  8. Cavalier King Charles Spaniels

Brief Description of Each Breed’s Predisposition

  • Boxers: Known for their distinctive square-shaped muzzle, Boxers have a natural inclination toward developing underbites due to their brachycephalic skull structure.
  • Bulldogs: The various Bulldog breeds share a similar facial structure, characterized by a short, wide muzzle, which increases their likelihood of having an underbite.
  • Pugs: With their wrinkled faces and flat noses, Pugs are another brachycephalic breed predisposed to underbites due to their skull shape and jaw configuration.
  • Shih Tzus and Lhasa Apsos: These small, long-haired breeds often exhibit underbites as a result of their shortened upper jaw relative to their lower jaw.
  • Pekingese: The Pekingese’s flat face and short muzzle make them another breed prone to developing underbites.
  • Boston Terriers: Known for their compact faces and square-shaped heads, Boston Terriers have a higher likelihood of having underbites because of their distinctive facial features.
  • Cavalier King Charles Spaniels: While not as prone to underbites as some of the other breeds mentioned, Cavalier King Charles Spaniels may still develop the condition due to their somewhat shortened muzzles.

How To Identify A Puppy With An Underbite

To identify a puppy with an underbite, pay close attention to their facial structure and dental alignment. Here are some signs to look for:

  1. Lower front teeth protruding in front of the upper front teeth when the mouth is closed.
  2. An uneven or asymmetrical appearance of the puppy’s face, particularly around the muzzle area.
  3. Difficulty grasping or chewing on toys or food.
  4. Excessive drooling or difficulty swallowing.

Keep in mind that some puppies may not display noticeable signs of an underbite until they grow older and their adult teeth fully develop.

When to Consult a Veterinarian

If you suspect that a puppy may have an underbite, it is essential to consult a veterinarian for a professional assessment. The vet will perform a thorough examination, checking the alignment of the puppy’s teeth and jaws.

They may also recommend additional tests, such as dental x-rays, to evaluate the severity of the condition and determine the best course of action for the puppy’s dental care.

Early intervention can help to manage potential health issues and ensure your puppy’s overall well-being.
