Understanding Your Dog’s Swollen Eye

It's every dog owner’s concern when they notice something wrong with their pet’s health. One common issue that can cause alarm is a swollen eye. Whether it’s just one eye or both, the swelling can indicate anything from minor irritation to more severe health conditions. Understanding the possible causes, symptoms, and treatment options is crucial in ensuring your dog’s eye health is properly addressed.

What Causes Swollen Eyes in Dogs?

Swollen eyes, also known as periorbital swelling, can happen due to several factors. Some causes are relatively harmless, while others can be quite serious and require immediate veterinary attention. Here are the most common causes of eye swelling in dogs:

1. Allergic Reactions

Dogs are prone to environmental allergies, much like humans. Pollen, dust mites, and insect bites are common culprits. Even certain foods or cleaning products may trigger an allergic reaction, leading to swelling and irritation around the eyes.

• Symptoms: Redness, watery discharge, pawing at the eyes.
• Treatment: Antihistamines or other allergy medications prescribed by your vet.

2. Foreign Objects & Trauma

A foreign object like dust, sand, or plant material can easily get lodged in a dog’s eye, leading to swelling and discomfort. Physical trauma such as a scratch or bump to the eye can also cause the eye to swell.

• Symptoms: Excessive blinking, squinting, pawing at the eye, or visible debris.
• Treatment: Flush the eye with a sterile saline solution and consult a vet if irritation persists.

3. Infections: Bacterial, Viral, or Fungal

Various infections can result in a swollen eye. Conjunctivitis (pink eye), commonly known as pink eye, is one of the most frequent causes. Other infections, like bacterial or fungal, can also cause inflammation in the eye area.

• Symptoms: Yellow or green discharge, redness, and puffiness.
• Treatment: Your vet will likely prescribe antibiotics or antiviral eye drops to treat the infection.

4. Glaucoma

Glaucoma refers to increased pressure inside the eye, which can cause severe swelling. If left untreated, glaucoma can result in permanent vision loss.

• Symptoms: Bulging eye, cloudy appearance, irritability.
• Treatment: Immediate veterinary care, which may include medication or surgery to reduce the pressure.

5. Eyelid Abnormalities (Entropion & Ectropion)

Entropion and ectropion are conditions where the eyelid rolls inwards or outwards, respectively. These abnormalities can cause chronic irritation, leading to swelling and discomfort.

• Symptoms: Tearing, visible abnormal eyelid position.
• Treatment: Surgical correction may be needed to fix the eyelid’s position.

6. Tumors and Growths

Benign or malignant tumors around the eye area can lead to swelling. Early detection is key to ensuring effective treatment and preventing complications.

• Symptoms: Visible lumps near the eye, rapid or slow growth.
• Treatment: Surgical removal, followed by a biopsy to check for malignancy.

7. Dental or Sinus Issues

In some cases, infections in the dog’s teeth or sinuses can spread to the eyes, causing swelling in the surrounding area.

• Symptoms: Swelling on one side of the face, nasal discharge, bad breath.
• Treatment: Treating the underlying infection through dental care or antibiotics.

8. Dry Eye (Keratoconjunctivitis Sicca)

Inadequate tear production can lead to dry eye syndrome, which causes inflammation and swelling. Dogs suffering from this condition may experience discomfort and pain.

• Symptoms: Red, dry eyes, excessive blinking or squinting.
• Treatment: Lubricating eye drops and possibly medication to stimulate tear production.

9.Insect Bites or Stings

• Symptoms: Insect bites or stings, such as from bees, wasps, or spiders, can cause sudden swelling around the eye.Rapid swelling, redness, and possible hives or itching around the affected area.
• Treatment: Cold compresses can be applied to the swollen area of your dog's eye with a cold towel or ice pack (wrapped in a towel to avoid direct contact with the skin).

When Should You Worry About Your Dog’s Swollen Eye?

While some cases of swollen eyes in dogs are minor and can be managed at home, there are signs that indicate the need for immediate veterinary intervention. If your dog shows any of the following symptoms, it's time to contact your vet:

• Prolonged swelling (more than 48 hours)
• Visible trauma or injury to the eye
• Yellow or green eye discharge (a sign of infection)
• Severe pain, indicated by squinting or reluctance to open the eye

How to Treat Your Dog’s Swollen Eye at Home

If the cause of your dog’s eye swelling is mild and you’re waiting for a vet appointment, there are a few home remedies you can try to alleviate discomfort:

• Eye Rinse

Gently flush the eye with a saline solution to remove debris or irritants.

• Cool Compress

Apply a cool, damp cloth to the swollen area to reduce inflammation.

• Antihistamines

If allergies  seem to be the cause, consult your vet about safe antihistamine options.

• Tea Bags

Place cooled, damp tea bags over the eye for a soothing effect.

Dietary adjustments

• Reduce fat intake: avoid feeding fatty foods such as cream and meat that may aggravate eye discomfort.
• Increase fruits and vegetables: Fruits and vegetables rich in vitamins and minerals, such as carrots and tomatoes, can strengthen your dog's eye resistance.
• Eat a light diet: Choose foods that are easy to digest and do not irritate the eyes, avoid spicy and pickled foods.
• Increase food moisture: helps your dog take in better nutrients, especially when tears may increase.
• Drink plenty of water: Keeping the body hydrated will help remove waste and keep the eyes moist.
• Choose easily digestible foods: Cooked chicken and white rice, for example, as well as moderate feeding of foods containing gelatinous substances, such as lean meat broth, will help maintain healthy eye tissues.
• Watch your vitamin C intake: Vitamin C helps repair eye tissues and boost immunity. 

Living Environment Adjustment

1. Avoid bright light irritation: avoid exposing your dog to bright light during an eye injury or infection to reduce eye pain and discomfort.
2. Regular review: Even if your dog's eye appears to have improved, you should take him to the veterinarian for regular review to ensure that the problem has been completely resolved.
3. Diet control: During the treatment period, your dog's diet should be controlled to avoid ingesting ingredients that are harmful to the body.
4. Use an eye patch: During treatment, you can equip your dog with a special eye patch to prevent him from accidentally rubbing or licking his injured eye.

With these adjustments, you can help your dog cope better with swollen eyes and promote a quick recovery. Remember to observe your dog's reactions closely and follow your veterinarian's professional advice while making adjustments to his diet and living environment.

How to Clean Your Dog's Eyes Properly When They Are Swollen ?

I. Prepare cleaning supplies

• Eye drops

If your dog's eyes are red and inflamed, you can use pet-specific eye drops. Eye drops can provide cleaning and anti-inflammatory effects and help relieve eye discomfort.

• Cotton balls or gauze

Choose a soft, clean cotton ball or gauze. The fibres of the cotton ball or gauze are not easy to leave behind, and the soft texture will not scratch the dog's eyes.

II. Cleaning Steps

• Wash hands

Before cleaning the dog's eyes, the operator should wash his hands first to prevent bacteria on his hands from contaminating the dog's eyes.

• Fix the dog's head

Gently fix the dog's head, you can use one hand to hold the dog's chin, the other hand for cleaning operations. Be gentle to avoid causing the dog to tense up and resist.

Pick up the eye drops with your other hand, place the bottle above your dog's eyes and gently squeeze the bottle to get the drops into your dog's eyes. Be careful not to let the mouth of the bottle touch your dog's eyes to avoid contaminating the drops.
The eye drops should be placed at the junction of the white of the eye and the eyelid, not directly on the eyeball.

• Order of wiping

Start at the inner corner of the eye and gently wipe towards the outer corner. For areas of discharge, apply a little pressure, but be very careful to avoid damaging the eyes. If there is a lot of discharge, replace the cotton ball or gauze with a new one and do not use the same one over and over again.

• Cleaning the edges of the eyelids

Be careful to clean the edges of your eyelids as well, where dirt and bacteria tend to accumulate. Gently wipe along the edge of the eyelid to remove any crusts or discharge that may be present.

III. Precautions

• During the cleaning process, take special care not to touch your dog's eyeballs directly. The eyeballs are very sensitive and fragile, and direct contact may lead to corneal damage and other problems.
• It is important to consult your veterinarian before using any medication, including the use of over-the-counter medications. Ensure that the eye drops used are pet-specific and do not use human eye drops, as certain ingredients may be harmful to dogs.
• Generally clean the eyes 2 - 3 times a day. If there is a lot of discharge, you can increase the frequency of cleaning appropriately, but you should also be careful to avoid over-cleaning that may cause irritation to the eyes.
• If your dog has trauma or ulcers in the eyes, take extra care when using eye drops to avoid further damage.
  Be gentle when applying eye drops to your dog to avoid causing unnecessary stress or injury. If you are unsure how to properly apply eye drops to your dog, it is recommended that you consult your veterinarian or be guided by him or her.
