Dog Face Swollen on One Side Under Eye: How to Address?

If you’ve ever noticed your dog face swollen on one side under eye, you’re not alone in your concern.

Recognizing and addressing this issue promptly is crucial for your pet’s well-being.

In this article, we’ll delve into the reasons behind this peculiar swelling, offering insights into the anatomy of a dog’s face, potential causes, and essential steps for treatment.

Key Notes

  • Pet owners should be vigilant for any changes in their dog’s appearance, especially face swelling, indicating potential underlying health problems or issues.
  • Dogs possess a complex facial structure, particularly around the eyes, making them susceptible to various issues.
  • Treatment for a swollen face varies and can include medications, surgery, or supportive therapies, emphasizing the need for personalized and comprehensive care.

Anatomy of a Dog’s Face and Eye Area

Dogs, like humans, have a complex facial structure. The area around the eye is particularly susceptible to various issues.

Understanding the anatomy allows pet owners to grasp potential reasons for face swelling better.

Eye Area Vulnerability

1.    Orbit and Eyeball: The eye is cradled within a protective orbit formed by bones like the frontal, maxilla, zygomatic, and palatine, making it susceptible to external pressures.

2.    Muscles and Soft Tissues: The eye is surrounded by muscles and soft tissues, contributing to movement and expression. However, this also makes the area prone to inflammation and swelling.

3.    Tear Glands and Drainage: Tear glands near the eye maintain ocular health, but disruptions in the drainage system can lead to issues like tear duct obstruction, impacting the delicate balance.

All these eye areas are susceptible to face swelling. Now, let’s discuss the causes of one-sided swollen face in dogs.

Causes of Face Swelling in Dogs

Here are the potential reasons for facial swelling whilst growing:

A. Allergic Reaction

Various allergens, including pollen, bee stings, dust, and certain foods, can trigger allergic reactions in dogs.

Recognizing and managing these allergens is essential for preventing facial swelling. Mild reactions tend to be less severe as compared to high allergic reactions.

B. Infection

Infections, such as tooth abscesses or conjunctivitis, can lead to facial swelling (mostly caused by viruses or bacteria). Timely professional diagnosis and treatment are crucial to prevent complications.

According to Dr Walaa Awadin (DVM, PhD) from Mansoura University, Eygpt, “Sometimes subcutaneous facial swelling in dogs is caused by mucor species.”

Veterinarians may conduct tests, including bloodwork and imaging, to identify the specific infection causing the facial swelling. Treatment plans may include antibiotics, antiviral medications, or other interventions.

C. Traumatic Injury Trauma

Bites (generally animal bites or bug bites), scratches, foreign objects in the eye, oral injuries, or blunt force injuries can result in facial swelling.

Immediate veterinary attention is necessary to assess the extent of the facial injury and initiate appropriate treatment.

In cases of traumatic injury trauma, seeking emergency veterinary care is paramount.

Minimal intervention can prevent complications and promote a speedy recovery for your pet and also reduces the chances of any future underlying health complications.

D. Dental Issues

Dental health issues such as dental infections, broken teeth, abscesses, impactions, oral injuries, or some hereditary dental issues (such as any periodontal disease) can cause facial swelling in dogs.

Regular dental check-ups and prompt treatment are essential for maintaining oral health.

According to Dr Sandra Manfra Marretta (DVM) from the University of Illinois, United States, “Facial Swelling in dogs is generally associated with impaction of the deciduous and permanent maxillary fourth premolars.”

Treatment of Facial Swelling in Dogs

Addressing facial swelling in dogs involves a targeted approach once the underlying cause is identified.

The choice of treatment depends on factors such as the nature and severity of the issue. Treatments may encompass medications, surgical interventions, or other specialized approaches tailored to the specific diagnosis.

A. Medications

1.    Anti-Inflammatory Pain Meds:

Non-steroidal anti-inflammatory drugs (NSAIDs) can be prescribed to reduce inflammation and alleviate pain associated with facial swelling.

Corticosteroids may also be employed to mitigate severe inflammatory responses. They also act as pain medication for pets.

2.    Antibiotics:

If the face swelling is attributed to bacterial infections, a course of antibiotics may be administered to combat the underlying microbial issue. Antibiotic ointment can also be used in severe cases.

3.    Antihistamines:

In cases of allergic reactions causing face swelling, antihistamines can help manage symptoms by blocking histamine release.

B. Surgical Interventions

1.    Craniomandibular Osteopathy:

For dogs diagnosed with craniomandibular osteopathy, a condition characterized by abnormal bone growth in the jaw, surgical intervention (oral surgery) may be necessary.

Surgeons may opt for procedures to correct the bone growth anomaly, alleviating both face swelling and associated discomfort.

2.    Abscess Drainage:

In instances where face swelling results from an abscess, surgical drainage may be performed to eliminate the accumulated pus, promoting faster healing.

3.    Tooth Extraction:

Dental issues contributing to facial swelling, such as abscessed teeth, may require surgical extraction to address the root cause and prevent recurrence.

C. Supportive Therapies

1.    Warm Compresses:

Applying warm compresses to the swollen face can help reduce inflammation and provide comfort to the dog.

2.    Topical Treatments:

Depending on the cause, veterinarians may recommend topical treatments or ointments to address localized skin issues contributing to facial swelling in dogs.

How to Prevent Your Dog’s Face from Swelling?

Prevention is key to ensuring your dog’s overall well-being. Implementing proactive measures can significantly reduce the risk of facial swelling in dogs.

Maintaining a Clean Environment

Regularly cleaning your dog’s living environment helps minimize exposure to potential allergens and reduces the risk of allergic reactions.

Dental Care

Routine dental care, including regular cleanings and promptly addressing dental issues (especially in periodontal disease), is crucial for preventing facial swelling associated with dental problems.

Supervised Play and Interaction

Monitoring your dog during play and interaction with other animals helps prevent traumatic injuries that could lead to facial swelling whilst growing.


Is It Normal for a Dog’s Face to Swell Slightly After Playing with Other Dogs?

Sometimes, minor facial swelling can occur due to rough play or accidental bumps during interactions with other dogs.

However, if the swelling is persistent, severe, or accompanied by other concerning symptoms, it’s crucial to seek veterinary attention to rule out any underlying issues.

Can Certain Breeds Be More Prone to Facial Swelling in Dogs?

Certain dog breeds may be predisposed to specific health issues, including those that can lead to facial swelling.

Breeds with short noses, like Bulldogs and Pugs, might be more susceptible to respiratory or dental issues that can contribute to facial swelling.

When Should I Seek Veterinary Help For My Dog’s Facial Swelling?

Prompt veterinary attention is essential when the swelling is severe or if the cause is unclear. Timely intervention aids in proper diagnosis and treatment.

Can Any Allergic Reaction Cause Facial Swelling in Dogs?

Yes, allergic reactions to common environmental factors like pollen, dust, or certain foods can lead to facial swelling in dogs.

Managing and preventing such severe reactions (any allergic reaction) is key to minimizing this risk.

How Can I Differentiate Between a Mild Allergic Reaction and a More Serious Issue Causing Facial Swelling in My Dog?

Mild allergic reactions may cause slight facial swelling, but severe reactions or other underlying issues can lead to more pronounced swelling and discomfort.

If you observe difficulty breathing, extensive swelling, or any signs of distress, it’s an emergency, and immediate veterinary attention is crucial.

Mild reactions may be managed with antihistamines, but a veterinarian should assess the severity of the situation.
