Introduction to Underbites in Dogs
Have you ever noticed a dog with its bottom teeth sticking out, even when its mouth is closed? That’s an underbite! While it might give some dogs an adorably quirky expression, there’s more to underbites than meets the eye.
Why Do Some Dogs Have Underbites?
When the bottom jaw juts out more than the top jaw, it is known as an underbite. Various factors that can cause underbites include genetics, birth defects, and accidents. Here are a few reasons why some dogs get this problem and how their owners can deal with it accordingly.
Why It’s Important to Understand Underbites
Knowing the implications of an underbite can make a big difference in your dog’s dental health and overall well-being. From potential oral issues to preventive care, being informed is critical to ensuring your dog leads a happy, healthy life.
What is an Underbite in Dogs?
Canine malocclusion, or an underbite as it is more commonly known, refers to a dental condition where the lower teeth are protruding in front of the upper ones. This misalignment may affect a dog’s ability to chew food, eat, or even play properly.
Scissor Bite vs. Underbite
In a utopian world, all canines would possess a “scissor bite,” whereby their upper teeth eclipse their lower ones. Nevertheless, for certain dog breeds (such as Bulldogs, Pugs, and Shih Tzus), this is not the case; they typically have an underbite that makes them look adorable.

Common Dog Breeds with an Underbites
Several breeds are more prone to underbites due to their genetic makeup. These include:
- Bulldogs
- Pugs
- Shih Tzus
- Boxers
- Pekingese
Causes of Underbites
Understanding what causes underbites can help us manage them. The primary reasons include genetics, developmental issues, and physical trauma.
Genetic Factors
For many breeds, underbites are simply part of their genetic blueprint. Short-muzzled dogs, also known as brachycephalic breeds, often inherit this trait from their ancestors.

Developmental Issues
Sometimes, underbites develop as a puppy grows. Irregular growth patterns in the jawbone can lead to misalignment, resulting in an underbite.
Physical Trauma
In rare cases, physical trauma can cause an underbite. Injuries to the jaw during a dog’s developmental stages can lead to long-term dental issues.
Identifying an Underbite in Your Dog
Spotting an underbite in your dog can be straightforward if you know what to look for. From visual signs to behavioral changes, we’ll guide you through the process.
Visual Signs
An underbite is usually visible when your dog is relaxed. The lower teeth will extend beyond the upper teeth, giving your dog a unique smile.
Behavioral Signs
Dogs with underbites might show changes in their eating, chewing, and playing habits. If your dog struggles to chew food or seems uncomfortable when playing with toys, an underbite could be the culprit.
Veterinary Diagnosis
Veterinarians must conduct routine health examinations in order to notice an underbite in a dog or any other animal type. In an exam, your vet will evaluate the position of your dog’s jaw and suggest possible methods for treating it, if required.
Health Implications of Underbites
Even though an underbite may cause canines to appear cute, managing it improperly can put one’s life through so many health risks.
Potential Issues
Underbites can cause tooth-to-tooth and tooth-to-gum contact, leading to cuts, ulcers, infections, and tooth decay. If your dog has an underbite, it’s essential to monitor its oral health closely.
When to Seek Treatment
If your dog shows signs of oral pain or discomfort, it’s time to consult your vet. Conditions that require veterinary intervention include persistent bad breath, bleeding gums, and difficulty eating.
Caring for a Dog with an Underbite
Caring for a dog with an underbite involves a combination of daily care, preventive measures, and, in some cases, treatment options.
Daily Care Tips
Maintaining proper dental hygiene is vital. Brush your dog’s teeth regularly and choose the right food and toys to prevent oral issues.
Preventive Measures
Regular dental check-ups are a must for dogs with underbites. Watch for any changes in behavior or eating habits that might indicate a problem.
Treatment Options
In some cases, orthodontic treatment might be necessary. Discuss the cost and considerations of dental procedures with your vet to determine the best course of action for your dog.
