Why do dogs get eye boogers?
Updated: August 19, 2024Understanding Eye Boogers in Dogs
Eye boogers, also known as ocular discharge, are common in dogs and can vary in consistency and color. They can be clear and watery or thick and crusty. While occasional eye boogers are usually harmless, frequent or excessive discharge may indicate an underlying health issue.
Common Causes of Eye Boogers in Dogs
Normal Tear Production
Dogs produce tears to lubricate their eyes, which helps to keep their eyes moist and remove debris. This is a natural and necessary process. When tears mix with dust and other particles, they can form eye boogers. This is particularly noticeable in the morning, just like in humans.
Allergies
Dogs can suffer from allergies just like humans. Allergens such as pollen, dust, and certain foods can cause their eyes to water more than usual. This excess tearing can lead to the formation of eye boogers. Allergic reactions often come with additional symptoms like itching, redness, and sneezing.
Conjunctivitis
Conjunctivitis, also known as pink eye, is an inflammation of the conjunctiva, the tissue lining your dog's eyelids and covering the white part of the eye. This condition can cause eye boogers, redness, and swelling. Conjunctivitis can be caused by infections (bacterial, viral), allergies, or irritants.
Dry Eye (Keratoconjunctivitis Sicca)
Dry eye occurs when a dog’s tear glands don't produce enough tears to lubricate the eye. This can lead to thick, yellow or green discharge, which forms into eye boogers. Dry eye is often treated with medications to stimulate tear production.
Blocked Tear Ducts
Blocked or narrowed tear ducts can prevent tears from draining properly. As a result, tears may overflow and mix with debris, forming eye boogers. This condition can be congenital or result from infections or injuries.
Breed-Specific Tendencies
Certain breeds are more prone to eye boogers due to their facial structure. For example, brachycephalic breeds like Pugs and Bulldogs have shallow eye sockets, which can lead to tear overflow and eye boogers. Similarly, breeds with long hair around their eyes, like Shih Tzus and Maltese, may have more eye discharge due to irritation from hair.
Signs That Eye Boogers May Indicate a Problem
Color and Consistency
While occasional clear or slightly whitish discharge is typically normal, eye boogers that are yellow, green, or bloody can indicate an infection or other serious health issues. Thick, pus-like discharge is particularly concerning and warrants a visit to the veterinarian.
Frequency and Amount
If your dog frequently has large amounts of eye boogers, this could be a sign of an underlying problem. Consistent eye discharge that requires daily cleaning is not normal and should be evaluated by a vet.
Additional Symptoms
Accompanying symptoms such as redness, swelling, squinting, excessive blinking, or pawing at the eyes suggest discomfort and potential eye problems. These symptoms, combined with eye boogers, are a clear sign that your dog needs medical attention.
Prevention and Treatment
Regular Cleaning
Regularly cleaning your dog’s eyes can help prevent the buildup of eye boogers. Use a clean, damp cloth or a veterinary-recommended eye wipe to gently remove discharge. Be careful not to touch the eyeball itself.
Addressing Allergies
If allergies are the cause, identifying and removing the allergen can help reduce eye boogers. Your vet may recommend antihistamines or other medications to manage your dog’s allergic reactions.
Medications for Infections
For bacterial or viral infections, your veterinarian may prescribe antibiotics, antiviral medications, or other treatments. Prompt treatment is essential to prevent complications and more serious eye conditions.
Surgical Solutions for Blocked Tear Ducts
In cases of blocked tear ducts, surgery may be necessary to clear the obstruction or create a new drainage pathway. This is typically only recommended if other treatments have failed.
Diet and Nutrition
A balanced diet rich in essential nutrients can support your dog’s overall health, including eye health. Omega-3 fatty acids, vitamins A, C, and E, and antioxidants can help maintain healthy vision and reduce the risk of eye problems.
When to See a Veterinarian
If your dog’s eye boogers are persistent, thick, discolored, or accompanied by other symptoms like redness, swelling, or discomfort, it is crucial to seek veterinary care. Early diagnosis and treatment can prevent more serious complications and ensure your dog’s eyes remain healthy.
Rare and Niche Causes of Eye Boogers
Autoimmune Disorders
In rare cases, autoimmune disorders such as pemphigus or lupus can cause eye boogers and other ocular symptoms. These conditions cause the immune system to attack the body’s own tissues, including the eyes, leading to inflammation and discharge.
Fungal Infections
Fungal infections are less common than bacterial or viral infections but can also affect a dog’s eyes. These infections can cause persistent discharge and require specialized antifungal treatments.
Foreign Bodies
Sometimes, tiny particles of dust, sand, or other foreign bodies can get trapped in a dog’s eye, causing irritation and discharge. If you suspect a foreign body, it’s important to have it removed by a veterinarian to avoid further damage to the eye.
Genetic Factors
Certain genetic conditions can predispose dogs to eye issues that result in discharge. For example, progressive retinal atrophy (PRA) and cataracts can cause chronic eye problems and discharge.
Environmental Factors
Exposure to smoke, chemicals, wind, and other environmental factors can irritate a dog’s eyes and lead to increased tearing and eye boogers. Keeping your dog away from such irritants can help reduce the occurrence of eye discharge.
Unique Insights on Dog Eye Health
Understanding why dogs get eye boogers requires a multifaceted approach, considering both common and rare causes. Regular eye care, prompt medical attention for unusual symptoms, and a holistic view of your dog’s health can help manage and prevent eye boogers.

The tail of a dog is an extension of its spine, comprising multiple vertebrae known as the caudal vertebrae. These vertebrae are connected by muscles, tendons, and nerves, making the tail both flexible and sensitive. The tail's musculature allows for a variety of movements, from rapid wagging to subtle positioning changes. Understanding the anatomy is crucial because it highlights how intricately connected the tail is to a dog’s overall physical and neurological systems.
