Causes of Laryngeal Cancer in Dogs

The exact cause of laryngeal cancer in dogs is not well understood, but several factors may contribute to its development:

Genetics: Certain breeds may be predisposed to developing laryngeal cancer.
Usia: Older dogs are more likely to develop laryngeal cancer, possibly due to accumulated genetic mutations over time.
Faktor lingkungan: Exposure to pollutants, smoke, or other environmental toxins may increase the risk.

Symptoms of Laryngeal Cancer in Dogs

Recognizing the symptoms of laryngeal cancer early can lead to more effective treatment. Key symptoms to watch for include:

Breathing Difficulties: Struggling to breathe, wheezing, or noisy breathing.
Coughing: Persistent coughing, which may be accompanied by blood.
Swallowing Difficulties: Difficulty swallowing food or water, leading to weight loss.
Exercise Intolerance: Reduced ability to exercise or play due to breathing difficulties.
