Undershot Jaw Issues in Pekingese: Causes and Care
The Pekingese is one of the oldest dog breeds, dating back to the Imperial Court of China during the Tang Dynasty. Known for their lion-like appearance and playful, courageous nature, these small dogs have captured the hearts of many worldwide. However, a notable trait in this breed is the undershot jaw, which can present some feeding and dental challenges.
Understanding the Undershot Jaw in Pekingese
An undershot jaw, medically known as mandibular prognathism or class III malocclusion, occurs when the lower jaw extends further than the upper jaw, causing misalignment between the teeth. This underbite is a characteristic feature of the Pekingese due to their brachycephalic (short-headed) skull structure and is typically expected in the breed standard.
Unlike in other breeds where this condition might be considered abnormal or problematic, a slight undershot jaw in the Pekingese is normal. However, when severe, it can cause difficulties such as trouble closing the mouth fully, leading to problems with drinking, eating, and oral health.
Signs Your Pekingese May Have Jaw Issues
- Difficulty picking up food from the bowl
- Trouble biting into or chewing food, often swallowing chunks whole
- Excessive drooling when drinking or eating
- Visible misalignment of the upper and lower jaws
Causes of Undershot Jaws in Pekingese
The undershot jaw in Pekingese is largely genetic and linked to the breed’s natural jaw growth patterns. The lower jaw grows longer compared to the upper jaw, creating the typical underbite. Occasionally, other factors such as trauma, nutritional or endocrine issues, or abnormal puppy teeth development can influence jaw alignment, but these are less common in well-bred Pekingese.
Helping Your Pekingese Eat Comfortably
If your Pekingese struggles to chew or bite food due to jaw misalignment, there are practical steps you can take to help:
- Provide small bite-sized or specially formulated small kibble to make food easier to pick up and chew.
- If feeding fresh or homemade meals, cut ingredients into small pieces or liquefy the food for easier swallowing.
- Encourage regular feeding times to monitor your dog’s eating habits and adjust food texture if necessary.
Maintaining Oral Health
Dental care is especially important for Pekingese with undershot jaws as misaligned teeth can trap food and encourage plaque buildup, increasing the risk of periodontal disease.
- Brush your dog’s teeth regularly with dog-specific toothpaste to reduce tartar and maintain fresh breath.
- If your Pekingese is not used to brushing, introduce the process gradually during puppyhood or seek veterinary dental cleaning for older dogs.
- Watch for signs of tooth loss or oral discomfort and consult your vet promptly.
The Importance of Annual Vet Checks
Routine veterinary examinations are crucial for identifying any worsening jaw alignment issues or oral health problems early. This proactive approach makes treatment more effective and improves your dog's quality of life.
Choosing a Reputable Pekingese Breeder
Finding a Pekingese puppy from a responsible breeder who carefully selects pairings is vital. Ethical breeders avoid breeding dogs with severe jaw problems, helping reduce the incidence of extreme undershot jaws in puppies.
Reputable breeders also provide health clearances, guidance on caring for breed-specific traits, and support for new owners to ensure a healthy and well-adjusted puppy.
Conclusion
The undershot jaw is a defining and expected trait in Pekingese dogs, reflecting their unique brachycephalic facial structure. While it can present challenges in eating and dental health, with attentive care, appropriate diet adjustments, and regular veterinary visits, most Pekingese lead happy, comfortable lives.
Responsible ownership and choosing reputable breeders committed to health standards remain the best tools to manage this condition and maintain the breed’s charm and wellbeing for generations to come.
