Watery Eyes in Dogs: Causes and Treatment

If you’ve noticed your dog’s eyes looking wet, teary, or crusty, you’re not alone. Watery eyes in dogs are one of the most common concerns pet owners bring to the vet. Excessive tearing, also called epiphora, can range from a minor irritation to a sign of an underlying health issue that needs professional attention. The good news is that many causes are treatable once properly diagnosed. This guide will walk you through what causes watery eyes in dogs, what signs to watch for, and when it’s time to call your veterinarian at Parrish Veterinary Clinic.

What Are the Causes for Watery Eyes in Dogs?

Watery eyes in dogs can be caused by a wide range of conditions, from environmental triggers to structural eye problems. Here are some of the most common reasons your dog may have watery eyes:

Eye Infections

Bacterial or viral infections, such as conjunctivitis (pink eye), are a frequent cause of excessive tearing in dogs. When the tissue lining the eye becomes inflamed, the eyes respond by producing more tears. Eye infections in dogs can be contagious, so getting a proper diagnosis quickly is important, especially in multi-pet households.

Foreign Objects or Irritants

Dust, grass seeds, hair, and other debris can easily get into your dog’s eye and trigger excessive tearing as the eye tries to flush out the irritant. Dogs that spend time outdoors or in grassy environments are particularly prone to this type of irritation.

Blocked Tear Ducts

Tears normally drain through tiny ducts near the inner corner of the eye. When those ducts become blocked, tears spill down the face instead of draining properly. This is a common structural cause of dog eye discharge and watery eyes in dogs, particularly in certain breeds like Cocker Spaniels and Bulldogs.

Corneal Ulcers or Injury

A scratch or ulcer on the surface of the eye is painful and often causes the eye to water as a protective response. If you notice your dog pawing at their eye or squinting in addition to tearing, a corneal injury could be the cause.

Breed-Related Eye Anatomy

Brachycephalic breeds, such as Pugs, Shih Tzus, Bulldogs, and Boxers, are more prone to watery eyes due to their shallow eye sockets and prominent eyes. In these breeds, the facial structure itself can cause chronic tearing that requires ongoing management.

Glaucoma

Increased pressure within the eye, known as glaucoma, can cause tearing along with pain, cloudiness, and vision changes. This is a serious condition that requires immediate veterinary attention. If your dog’s eyes appear watery and their pupils look enlarged or uneven, contact Parrish Veterinary Clinic right away.

What Are the Signs of Watery Eyes in Dogs?

Not every teary eye looks the same. Recognizing the signs of watery eyes in dogs can help you describe what you’re seeing to your veterinarian and determine how urgent the situation is.

Common signs associated with excessive tearing in dogs include:

• Wet or damp fur beneath one or both eyes
• Reddish-brown tear staining on light-colored coats
• Clear, watery discharge from the eye
• Yellow, green, or cloudy discharge that may indicate infection
• Squinting, blinking excessively, or holding the eye shut
• Pawing or rubbing at the face
• Redness or swelling around the eye
• Crustiness or matting around the eyelids

Some of these signs point to a minor, temporary irritation, while others may signal something more serious. As a general rule, if your dog’s watery eyes are accompanied by pain, significant discharge, or cloudiness, it’s time to schedule a veterinary visit.

When Dog Eye Discharge Becomes a Concern

A small amount of clear discharge, especially in the morning, is often normal. But watery eyes in dogs that persist for more than a day or two, or that are paired with other symptoms, deserve professional evaluation. Our team at Parrish Veterinary Clinic is experienced in diagnosing the full range of canine eye conditions, from mild irritation to more complex issues like glaucoma or corneal damage.

Are Watery Eyes a Sign of Allergies?

Yes, allergies in dogs can absolutely cause watery eyes, and this is actually one of the more frequently overlooked causes. Just like people with hay fever, dogs can develop eye irritation and excessive tearing in response to environmental allergens.

Environmental Allergies and Dog Eye Discharge

Dogs with environmental allergies, also called atopy, often react to pollen, mold, dust mites, and grass. These allergens can trigger symptoms including itchy skin, sneezing, and watery eyes. If your dog’s eye tearing seems to worsen during certain seasons or after spending time outdoors, allergies may be the culprit.

Food Allergies and Watery Eyes

Food sensitivities can also manifest as eye irritation in some dogs. While skin and gastrointestinal symptoms are more commonly associated with food allergies, excessive tearing is a possible symptom. A veterinarian can help you determine whether a dietary factor might be contributing to your dog’s watery eyes through an elimination diet or allergy testing.

How Are Dog Eye Allergies Treated?

Treatment for allergy-related watery eyes in dogs depends on identifying and managing the trigger. Your vet may recommend antihistamines, prescription eye drops, or other medications to reduce inflammation and discomfort. In some cases, allergy testing and immunotherapy (allergy shots) may be appropriate for long-term management.

How Are Watery Eyes in Dogs Diagnosed and Treated?

When you bring your dog to Parrish Veterinary Clinic for watery eyes, your vet will start with a thorough eye exam to identify the underlying cause. This may include:

• A Schirmer tear test to measure tear production
• Fluorescein dye testing to detect corneal ulcers or scratches
• Tonometry to check for elevated eye pressure (glaucoma)
• Evaluation of the eyelid structure and position
• Assessment of the nasolacrimal (tear duct) drainage system

Treatment will depend on the specific diagnosis. Bacterial infections are typically treated with antibiotic eye drops or ointments. Allergic reactions may be managed with antihistamines or anti-inflammatory medications. Blocked tear ducts may require flushing or, in some cases, surgical correction. Corneal ulcers need targeted treatment based on their severity, which is why trying to treat watery eyes at home without a diagnosis isn’t recommended.
