Dysphagia in Dogs: Causes, Signs & Treatment Tips

Dysphagia in dogs refers to difficulty or discomfort while swallowing. This serious condition can affect various stages of the swallowing process, caused by issues like nerve damage, muscle weakness, pain, or physical obstructions. Prompt veterinary attention is essential to prevent complications such as aspiration pneumonia, a potentially fatal lung infection common in affected dogs.

Types of Dysphagia in Dogs

Dysphagia is categorized according to where the problem occurs during swallowing:

• Oral dysphagia: Difficulty swallowing food held inside the mouth, often due to jaw or tongue paralysis, dental disease, or muscle atrophy.
• Pharyngeal dysphagia: Trouble swallowing after food reaches the throat (pharynx), which may involve head and neck movements to assist swallowing, gagging, or nasal discharge.
• Cricopharyngeal dysphagia: Challenges at the junction where the throat connects to the esophagus. Symptoms usually include coughing, gagging, or vomiting food shortly after swallowing.

Identifying Symptoms of Dysphagia

Signs vary depending on the type but commonly include:

• Tilting or shaking the head while eating
• Throwing the head backward when swallowing
• Food becoming stuck in cheek folds, sometimes mixed with saliva
• Excessive chewing or gagging during meals
• Multiple swallowing attempts accompanied by coughing or vomiting
• Nasal discharge linked to swallowing difficulty
• Weight loss caused by insufficient nutrient intake

Common Causes of Dysphagia

Underlying issues contributing to dysphagia include:

• Dental problems and oral infections causing pain
• Trauma to the jaws or throat, such as jaw dislocation
• Inflammation or abscesses in the mouth, pharynx, or esophagus
• Tumors or growths obstructing the swallowing pathway
• Neurological disorders like cranial nerve injuries or myasthenia gravis affecting muscle coordination
• Muscle diseases including polymyositis and muscular dystrophy
• Structural abnormalities such as cleft palate or unusual tongue tissue
• Foreign objects lodged in the mouth or esophagus

Diagnosing Dysphagia: American Veterinary Approach

Diagnosis usually involves multiple steps:

1. Taking a detailed history and timeline of symptoms with the dog owner
2. Performing a complete physical exam focusing on the mouth, throat, and neck areas
3. Running blood work including chemistry panels, complete blood count, and urinalysis to check for infections or systemic conditions
4. Imaging techniques such as X-rays, ultrasound, CT, or MRI scans help visualize obstructions, inflammation, or tumors
5. Endoscopy to directly examine the throat and esophagus may be necessary
6. Specialist tests like muscle biopsies or electromyography may be used for suspected neuromuscular causes

Advanced diagnostic methods have become standard in the U.S., including videofluoroscopic swallow studies (VFSS), which are the gold standard for evaluating swallowing function with real-time imaging. Fiberoptic endoscopic evaluation of swallowing (FEES) is also emerging for use in awake dogs to assess oropharyngeal swallowing without radiation exposure.

Treatment Tailored to the Cause

Therapy depends on the underlying diagnosis and may include:

• Supportive feeding: Hand feeding small amounts placed at the back of the mouth or holding the dog’s head upright to facilitate safer swallowing
• Medical treatment: Antibiotics for infections, steroids for inflammation, and medications for neuromuscular disorders
• Surgery: Removal of foreign objects, tumors, or repair of anatomical defects when indicated and safe
• Tube feeding: Placement of feeding tubes may be required for dogs who cannot maintain adequate nutrition orally
• Physical therapy and rehabilitation: Exercises that improve muscle strength and swallowing function in some cases

Living with a Dog That Has Dysphagia

Caring for a dog with swallowing difficulties requires attention and patience:

• Offer smaller meals more often to reduce stress and choking risk during feeding
• Keep the dog upright during feeding to help prevent aspiration pneumonia (lung infection from inhaling food or fluids)
• Regularly monitor weight and overall condition to ensure nutritional needs are met
• Seek immediate veterinary care if signs like coughing, labored breathing, or nasal discharge worsen
• Understanding that some cases need ongoing supportive care for the best quality of life

Though dysphagia itself may not always be fatal, its complications can become severe. Early diagnosis and care by a knowledgeable American veterinarian greatly improve recovery chances and wellbeing.

If you notice your dog having trouble swallowing or show any signs mentioned, consult your local veterinarian promptly for expert evaluation and a tailored treatment plan fit for your canine companion's needs.
