Lingual Frenulum Disorders in Dogs: Causes and Treatment

Lingual frenulum disorders in dogs, commonly called ankyloglossia or "tongue-tie," are a rare congenital condition affecting the tissue connecting the underside of the tongue to the mouth's floor. Normally, this frenulum allows the tongue to move freely, but in affected dogs, it is short, thickened, or abnormally attached to the gums, restricting tongue mobility and causing difficulties in eating, drinking, swallowing, panting, and even vocalising.

Notably, breeds such as the Kangal Dog and Anatolian Shepherd Dog appear more predisposed to this disorder, especially in cases of close interbreeding. Responsible breeding practices are vital to avoid perpetuating this hereditary condition.

Understanding Lingual Frenulum Disorders in Dogs

The lingual frenulum is a flexible band of tissue connecting a dog's tongue to the floor of its mouth, allowing free tongue movement essential for feeding, drinking, and panting. In ankyloglossia, this frenulum is abnormally short, thick, or attached to parts of the gums, significantly limiting tongue movement. Some affected dogs' tongues may appear notched or take on a "W" shape due to the frenulum's abnormal attachment.

Such limited tongue mobility leads to difficulties:

• Eating solid foods and drinking water, potentially causing dehydration and weight loss.
• Swallowing properly, increasing the risk of aspiration pneumonia if food or water is inhaled into the lungs.
• Thermoregulation through panting, as restricted tongue movement can impair cooling.
• Vocalisation, affecting a dog's normal communication.

The Genetic Link and Predisposed Breeds

Research indicates a genetic component involving dogs' T-Box genes affecting the development of the lingual frenulum, though exact causes remain unclear. The disorder manifests during foetal development, and more studies are needed to better understand why some breeds, particularly the Kangal Dog, are more susceptible.

Close interbreeding within predisposed breeds increases the prevalence of this condition, making genetic diversity and responsible breeding critical to minimising risk.

Surgical Correction: Lingual Frenuloplasty

The primary treatment for dogs born with lingual frenulum abnormalities is surgical correction known as lingual frenuloplasty. This procedure involves carefully cutting and repositioning or removing the restrictive frenulum tissue to restore normal tongue mobility.

Surgery aims to:

• Allow the dog to eat, drink, and swallow comfortably and effectively.
• Enable normal tongue movement for panting and vocalising.
• Improve overall quality of life and prevent secondary health issues such as malnutrition and aspiration pneumonia.

Post-operative care includes hand feeding the dog while the tongue heals and ensuring they are fed in an upright position to facilitate swallowing and reduce the risk of aspiration pneumonia. Recovery is generally rapid, with most dogs regaining normal function quickly.

Prognosis and Long-Term Management

Following successful surgery, dogs typically recover well and begin gaining weight due to improved nutrition and hydration. Owners should monitor their dog closely in the initial weeks post-surgery, adhering to vet guidelines on feeding and oral care.

Moreover, it is advisable not to breed affected dogs to prevent passing the disorder to offspring. If you're considering getting a Kangal Dog or similar breed, ensure you find a reputable breeder who prioritises health screenings and responsible practices to reduce congenital risks.

Other Oral Anomalies in Dogs

While ankyloglossia is the most documented lingual frenulum disorder, other oral anomalies can affect dogs, including:

• Microglossia: An underdeveloped tongue causing severe feeding difficulties and often poor prognosis.
• Macroglossia: An abnormally large tongue observed in some breeds, leading to nursing problems.

If you observe unusual tongue shape or feeding difficulties in your dog, a prompt veterinary assessment is essential for diagnosis and treatment planning.

Responsible Ownership and Conclusion

Lingual frenulum disorders, while rare, can have a significant impact on affected dogs' health and wellbeing. Early recognition and surgical treatment can lead to excellent outcomes. Responsible breeding and choosing puppies from trustworthy breeders with appropriate health screenings are key to minimising these congenital conditions.

If you are looking to find a puppy, particularly from breeds known to have genetic predispositions, take the time to research breeders who prioritise health and genetic testing to ensure your new family member has the best start in life.

For any dog showing signs of feeding or swallowing difficulties, consult your vet promptly to explore diagnostic and treatment options. With dedication and care, dogs with lingual frenulum disorders can lead happy, healthy lives.
