Dogs With Underbites: What You Need to Know

An underbite in dogs is a skeletal condition where the lower jaw protrudes further than the upper jaw, causing the lower teeth to overlap the upper teeth. While many people find this endearing, it’s important to understand the potential health implications and responsible breeding practices associated with underbites in dogs.

This comprehensive guide delves into the causes of underbites, the breeds commonly affected, and potential health concerns. We will also discuss what you can do if your dog has an underbite and how to ensure their well-being.

Understanding Underbites in Dogs

An underbite, also known as a Class III malocclusion, is a form of malocclusion, a misalignment of the teeth and jaws. It can range from a slight overbite to a severe protrusion of the lower jaw. While some underbites are purely aesthetic, others can impact a dog’s ability to eat, drink, and even breathe properly.

Causes of Underbites in Dogs

Underbites are primarily a genetic trait, often passed down from parent dogs to their offspring. Certain breeds, like Bulldogs and Pugs, are selectively bred for their flat faces and short muzzles, which often result in an underbite. However, underbites can also develop due to:

Early loss of baby teeth: If a puppy loses its baby teeth too early, it can disrupt the alignment of the adult teeth, potentially leading to an underbite.
Injury to the jaw: Trauma or injury to a puppy’s jaw during development can alter jaw growth and cause an underbite.
Tumors in the mouth or jaw: While less common, tumors can impact jaw alignment and lead to an underbite in dogs.

Breeds Prone to Underbites

While any dog breed can develop an underbite, some are genetically predisposed to it. Breeds with short muzzles and flat faces, known as brachycephalic breeds, are particularly susceptible. These include:

Bulldogs (English, French, American)
Pugs
Shih Tzus
Boxers
Boston Terriers
Pekingese
Japanese Chins

It’s important to remember that not all dogs of these breeds will have an underbite, and the severity can vary significantly.

Potential Health Issues Associated with Underbites

While mild underbites may not pose significant health risks, moderate to severe underbites can lead to various complications, including:

Dental Problems: Difficulty chewing properly can result in uneven wear and tear on teeth, leading to dental disease, fractured teeth, and gum problems.
Eating and Drinking Difficulties: Severe underbites can make it challenging for dogs to pick up food or drink water efficiently.
Jaw Pain: Misaligned jaws can cause chronic pain and discomfort.
Breathing Problems: In brachycephalic breeds, an underbite can exacerbate breathing issues already present due to their shortened airways.
Eye Injuries: Dogs with protruding lower jaws are more prone to eye injuries as their eyes are less protected.

What to Do if Your Dog Has an Underbite

If you notice your dog has an underbite, it’s essential to consult with your veterinarian. They can assess the severity of the underbite and determine if it requires treatment.

Treatment options for underbites can include:

Dental braces: In some cases, braces can help correct underbites in puppies and young dogs.
Tooth extraction: If overcrowding or misaligned teeth cause problems, your vet may recommend extracting certain teeth.
Surgery: For severe cases, surgical intervention might be necessary to reshape the jaw and improve functionality.

Living with a Dog with an Underbite

While underbites can present challenges, with proper care and attention, dogs with underbites can lead happy and fulfilling lives. Here are some tips for caring for a dog with an underbite:

Regular Veterinary Checkups: Frequent dental checkups are crucial to monitor dental health and address any issues early on.
Dental Hygiene: Establish a consistent dental care routine that includes brushing your dog’s teeth regularly and providing dental chews.
Food and Water Bowls: Use shallow, wide-bottomed bowls to make it easier for your dog to eat and drink comfortably.
Monitor for Changes: Pay attention to any changes in your dog’s eating habits, behavior, or breathing, and consult your vet if you notice anything concerning.

Responsible Breeding Practices

If you’re considering getting a puppy from a breed prone to underbites, it’s vital to choose a responsible breeder who prioritizes the health and well-being of their dogs. Responsible breeders will screen their breeding dogs for genetic conditions, including malocclusions, to minimize the risk of passing on these traits to their offspring.

Conclusion

Understanding underbites in dogs is crucial for responsible pet ownership. While a mild underbite might simply be a charming quirk, more severe cases can lead to health complications. By being aware of the causes, potential issues, and treatment options, you can ensure your dog receives the best possible care and enjoys a happy and healthy life.

FAQs

1. Are underbites painful for dogs?

While mild underbites might not cause discomfort, moderate to severe underbites can lead to jaw pain, difficulty eating, and other health issues that can impact a dog’s quality of life.

2. Can an underbite be corrected in adult dogs?

Correcting an underbite in adult dogs is more complex than in puppies. While braces might be an option in some cases, surgery is often the only viable solution for severe underbites in adult dogs.

3. Can I prevent my dog from developing an underbite?

Since underbites are primarily genetic, preventing them entirely can be challenging. However, choosing a responsible breeder who screens for genetic conditions can significantly reduce the risk.

4. Are certain types of dog food better for dogs with underbites?

Softer foods, such as wet food or kibble softened with water, can be easier for dogs with underbites to eat. Consult with your vet to determine the best diet for your dog’s individual needs.

5. Can an underbite shorten my dog’s lifespan?

While a mild underbite might not significantly impact lifespan, severe underbites that lead to health complications can potentially shorten a dog’s life expectancy.
