If you’ve noticed your furry friend having some gunk in their eyes, don’t worry – it’s actually quite common! Dogs can develop eye boogers for various reasons, and it’s important to understand what might be causing them. One common culprit is conjunctivitis, which is characterized by inflammation of the tissue that covers the front part of the eyeball and lines the eyelids. Another condition to watch out for is canine dry eye, where inadequate tear production results in eye discharge. Epiphora, which is the overflow of tears from the eyes, can also be a signal of an underlying issue. Some dog breeds, particularly those with bulging eyes, are more prone to eye problems and excessive discharge. If you’re seeing excessive or abnormal eye discharge in your pup, it’s always a good idea to bring them to a veterinarian for proper diagnosis and treatment.

Conjunctivitis
Definition
Conjunctivitis is a common condition in dogs that leads to eye discharge. It is characterized by the inflammation of the tissue that covers the front part of the eyeball and lines the eyelids, known as the conjunctiva. This inflammation causes redness, irritation, and the production of excessive mucus or discharge from the eyes.
Causes
There are several causes of conjunctivitis in dogs. It can be a result of allergies, bacterial or viral infections, or foreign bodies in the eye. Sometimes, conjunctivitis can also be caused by underlying health conditions such as dry eye or entropion.
Symptoms
If your dog has conjunctivitis, you may notice a variety of symptoms. These can include redness in the eyes, swelling of the eyelids, excessive tearing, discharge that may be clear, white, or yellowish in color, and frequent blinking or squinting. Your dog may also paw at their eyes or rub their face on objects to relieve the discomfort.
Diagnosis
To diagnose conjunctivitis in your dog, it is important to visit a veterinarian. They will examine your dog’s eyes and may perform additional tests if necessary. These can include taking a sample of the discharge for laboratory analysis or using special dyes to check for any scratches or ulcers on the cornea.
Treatment
The treatment for conjunctivitis will depend on the underlying cause. If it is caused by an infection, your veterinarian may prescribe antibiotic eye drops or ointments. Allergic conjunctivitis can be managed with antihistamines or corticosteroids. It is important to follow the veterinarian’s instructions and administer the medication as directed. In some cases, your dog may also require supportive care such as cleaning the eyes or applying warm compresses to alleviate any discomfort.
Viral Infection
Definition
Viral infections can also cause eye discharge in dogs. These infections are typically caused by viruses that can be transmitted from other infected animals, such as other dogs or through contact with contaminated objects.
Causes
The most common viral infections that can cause eye discharge in dogs include canine distemper, canine adenovirus, and canine herpesvirus. These viruses can be highly contagious and can spread easily among dogs, particularly in areas with a high population or where dogs are in close proximity.
Symptoms
The symptoms of a viral eye infection can vary depending on the specific virus involved. However, common symptoms include redness, swelling, watery or thick discharge, and sensitivity to light. Dogs with viral eye infections may also exhibit general signs of illness, such as fever, lethargy, or a decreased appetite.
Diagnosis
To diagnose a viral eye infection, a veterinarian will perform a physical examination and review the dog’s medical history. While some viral infections can be confirmed through specific tests, such as viral cultures or PCR tests, others may be diagnosed based on clinical signs and the presence of other symptoms.
Treatment
Treatment for viral eye infections in dogs focuses on managing the symptoms and supporting the dog’s immune system. In most cases, the viral infection needs to run its course, and the body’s immune system will fight off the infection over time. The veterinarian may prescribe medication to help alleviate discomfort or address any secondary bacterial infections. It is important to provide supportive care, such as keeping the eyes clean and providing a comfortable environment for the dog to rest and recover.
Canine Dry Eye (Keratoconjunctivitis Sicca)
Definition
Canine dry eye, also known as Keratoconjunctivitis Sicca, is a condition that can lead to eye discharge in dogs. It occurs when there is inadequate tear production, resulting in dryness and irritation of the eyes.
Causes
The primary cause of canine dry eye is a malfunction of the tear glands, specifically the lacrimal glands, which are responsible for producing tears. This malfunction can be due to immune-mediated conditions, hereditary factors, or certain medications that suppress tear production.
Symptoms
If your dog has dry eye, you may notice symptoms such as thick discharge from the eyes that may be sticky or mucus-like. The eyes may also appear red and inflamed, and your dog may paw at them or rub their face to relieve the discomfort. Dry eye can also lead to other complications, such as corneal ulcers, if left untreated.
Diagnosis
To diagnose canine dry eye, a veterinarian will perform a series of tests, including a Schirmer tear test. This test measures the amount of tears produced by the eyes over a certain period of time. A low tear production indicates dry eye. The vet may also examine the eyes using special dyes to check for any damage to the cornea.
Treatment
Treating canine dry eye usually involves managing the underlying cause and providing artificial tears to lubricate the eyes. Your veterinarian may prescribe medication to stimulate tear production or recommend frequent use of artificial tear drops or ointments. It is important to follow the prescribed treatment plan and monitor your dog’s progress.
Foreign Body
Definition
A foreign body in the eye refers to any object or substance that enters and gets trapped in the eye, causing irritation and leading to excessive eye discharge.
Causes
Foreign bodies can enter a dog’s eye in various ways. Common causes include dust, dirt, sand, grass seeds, or other small particles that can accidentally get into the eye. Dogs that spend time outdoors, particularly in areas with tall grass or dusty environments, are more prone to foreign bodies entering their eyes.
Symptoms
If your dog has a foreign body in their eye, you may observe symptoms such as excessive tearing, squinting, or blinking. Your dog may rub or paw at their eye, indicating discomfort or irritation. In some cases, you may notice a visible object or debris lodged in the eye.
Diagnosis
Diagnosing a foreign body in the eye usually requires the assistance of a veterinarian. They will carefully examine your dog’s eye using special instruments and may use local anesthesia to perform a more detailed examination. The presence of a foreign body can often be confirmed through visual inspection or through the use of special dyes.
Treatment
Treatment for a foreign body in the eye involves removing the object or substance causing the irritation. This should only be done by a veterinarian or a trained professional, as mishandling can cause further injury or damage to the eye. Depending on the size and location of the foreign body, your veterinarian may use specialized tools, flushing techniques, or anesthesia to safely remove it. After removal, antibiotic eye drops or ointments may be prescribed to prevent infection and promote healing.
Epiphora
Definition
Epiphora is a condition characterized by the overflow of tears from the eyes. It can be a symptom of an underlying condition and can lead to excessive eye discharge in dogs.
Causes
There are various causes of epiphora in dogs. It can be a result of an eye infection, allergies, anatomical abnormalities, or blocked tear ducts. Certain dog breeds with excessive skin folds around the eyes, such as Bulldogs or Pugs, may also be more prone to epiphora.
Symptoms
The main symptom of epiphora is excessive tearing from the eyes, resulting in wet fur around the eyes or tear stains on the face. Your dog may have a constant watery discharge, and the fur in the affected area may become matted or discolored. Some dogs with epiphora may also develop skin irritation or infection due to the constant moisture.
Diagnosis
To diagnose the cause of epiphora in your dog, a veterinarian will evaluate the eyes and may perform additional tests. This can include examining the tear ducts for any blockages or abnormalities, taking a sample of the discharge for analysis, or using special dyes to check for any damage to the cornea.
Treatment
Treating epiphora involves addressing the underlying cause. Depending on the diagnosis, your veterinarian may recommend medication to treat any infections or allergies, or they may suggest a minor surgical procedure to correct any anatomical abnormalities or to unblock the tear ducts. Regular cleaning and grooming of the area around the eyes may also be necessary to maintain hygiene and prevent further irritation.
Entropion
Definition
Entropion is a genetic condition in dogs where a portion of the eyelid is folded inward, causing the eyelashes or fur to rub against the surface of the eye. This constant friction can result in excessive tears and mucus discharge, leading to eye boogers.
Causes
Entropion is primarily caused by a genetic predisposition. Certain dog breeds, such as Bulldogs, Chow Chows, and Shar-Peis, are more prone to developing this condition. It occurs when the eyelid fails to develop properly, causing it to roll inward. This inward rolling can irritate the eye and cause excessive tearing.
Symptoms
The main symptom of entropion is the excessive tearing or discharge from the affected eye. Your dog may also show signs of discomfort or pain, such as frequent blinking, squinting, or pawing at the eye. If left untreated, entropion can lead to corneal ulcers or other complications.
Diagnosis
To diagnose entropion, a veterinarian will examine your dog’s eyes and eyelids. They may perform additional tests, such as using special dyes to check for any corneal abrasions or ulcers caused by the constant rubbing of the eyelashes against the eye. Genetic screening may also be recommended, especially in certain breeds known to be predisposed to entropion.
Treatment
The treatment for entropion usually involves surgical correction. The veterinarian will carefully trim excess skin and adjust the eyelid to prevent it from folding inward. In some cases, multiple surgeries may be required to achieve optimal correction. Post-surgery, your dog may require pain medication and antibiotics to ensure proper healing. Regular follow-up visits with the veterinarian are important to monitor the progress and address any potential complications.
Genetic Predisposition
Breeds Prone to Eye Discharge
Certain dog breeds are predisposed to developing eye issues and excessive eye discharge. These breeds often have specific anatomical features that make them more susceptible to eye problems.
Some breeds known to be prone to eye discharge include Bulldogs, Pugs, Boxers, Shih Tzus, and Cocker Spaniels. These breeds typically have prominent or bulging eyes, which can lead to the accumulation of debris or mucus and increase the risk of eye infections and irritation.
Causes
The genetic predisposition for excessive eye discharge in certain breeds is primarily due to their anatomical structure. The shape of the eyes, eyelids, and tear ducts can influence tear production, drainage, and the likelihood of debris or irritants getting trapped in the eyes.
Symptoms
The symptoms of eye discharge in breeds prone to genetic predisposition are similar to those of other eye conditions. These can include excessive tearing, discharge that may be thick or mucus-like, redness or inflammation of the eyes, and discomfort or pain experienced by the dog.
Diagnosis
A veterinarian can diagnose the genetic predisposition to eye discharge in certain breeds based on the physical examination of the dog’s eyes and a review of the breed’s medical history. Special tests, such as genetic screenings or eye exams, may also be recommended to determine the extent of the genetic predisposition and identify any associated health issues.
Treatment
Treatment for breeds prone to eye discharge focuses on managing the underlying cause and providing symptomatic relief. Regular maintenance and cleaning of the eyes, using specific eye drops or ointments recommended by the veterinarian, can help reduce eye discharge. In some cases, surgical intervention may be necessary to correct any anatomical abnormalities or prevent further complications.
Bacterial Infection
Definition
Bacterial infections can be a common cause of eye discharge in dogs. These infections occur when bacteria enter the eyes, leading to inflammation and excessive discharge.
Causes
Bacterial infections in the eyes can occur due to numerous factors. These can include trauma to the eye, such as scratches or injuries that allow bacteria to penetrate the eye’s protective barrier. Additionally, bacterial infections can be secondary to other underlying conditions, such as conjunctivitis or dry eye, which create an environment conducive to bacterial growth.
Symptoms
The symptoms of a bacterial eye infection may include redness, swelling, discharge that is thick or pus-like, and a foul odor. Your dog may also exhibit signs of discomfort, such as rubbing or pawing at their eyes, squinting, or keeping the affected eye closed. In severe cases, the infection can cause corneal ulcers or lead to more serious complications if left untreated.
Diagnosis
Diagnosing a bacterial eye infection requires a veterinarian’s expertise. They will examine your dog’s eyes and may take a sample of the discharge for laboratory analysis. The analysis can determine the presence of bacteria and help guide the appropriate treatment plan.
Treatment
Treatment for a bacterial eye infection typically involves the use of antibiotic eye drops, ointments, or systemic antibiotics, depending on the severity of the infection. The veterinarian may also recommend regular cleaning of the eyes and warm compresses to help alleviate discomfort and promote healing. It is important to administer the prescribed medications as directed and attend any follow-up appointments to monitor the progress.
Allergic Reaction
Definition
Allergic reactions can cause eye discharge in dogs. These reactions occur when the immune system responds to a specific allergen, leading to inflammation of the eyes and excessive tearing.
Causes
Common allergens that can trigger an allergic reaction in dogs include pollen, dust mites, certain foods, or certain chemicals found in grooming products or cleaning agents. Dogs can also develop allergies to certain fabrics or materials used in bedding or toys.
Symptoms
The symptoms of an allergic reaction in the eyes can include redness, itching, swelling of the eyelids, and excessive tearing or discharge. Your dog may rub or scratch at their eyes, leading to further irritation or potential injury. Allergic reactions can also cause other symptoms, such as sneezing, coughing, or skin irritation.
Diagnosis
Diagnosing an allergic reaction requires a thorough examination by a veterinarian. They will evaluate the dog’s medical history and perform physical tests, such as skin prick tests or blood tests, to identify the specific allergens triggering the reaction. In some cases, the veterinarian may refer you to a veterinary dermatologist for further evaluation and testing.
Treatment
The treatment for allergic reactions in dogs often involves managing the symptoms and avoiding exposure to the allergen. Your veterinarian may prescribe antihistamines or corticosteroids to help alleviate the allergic response and reduce eye discharge. Additionally, they may recommend changes to the dog’s environment or diet to prevent further allergic reactions. Regular cleaning and grooming of the dog’s bedding and toys can also help minimize exposure to allergens.
Conclusion
Excessive eye discharge in dogs can be caused by various factors, including conjunctivitis, dry eye, epiphora, entropion, genetic predisposition, foreign bodies, bacterial infections, viral infections, or allergic reactions. If your dog has abnormal eye discharge, it is important to seek veterinary attention for a proper diagnosis and treatment plan. Early detection and appropriate care can help prevent further complications and promote the overall health and well-being of your furry friend.
