Why does a dog have watery eyes and what to do? - briefly
A dog may have watery eyes due to allergies, infections, or eye irritants like dust or smoke. To address this issue, consult a veterinarian who can prescribe appropriate medication or suggest hygiene improvements to alleviate the symptoms.

Why does a dog have watery eyes, and what can be done about it?
Watery eyes in dogs, also known as epiphora, are a common condition that can be caused by various factors. Understanding these factors is crucial for proper diagnosis and treatment.
One of the primary causes of watery eyes in dogs is the obstruction or narrowing of the nasolacrimal ducts. These ducts connect the eye to the nose and are responsible for draining tears away from the eye. If these ducts become blocked, tears cannot drain properly, leading to excessive tearing and watery eyes. This condition is known as nasolacrimal duct obstruction (NLDO).
Another common cause of watery eyes in dogs is conjunctivitis, an inflammation or infection of the conjunctiva, the mucous membrane that lines the eyelids and covers the white part of the eye. Conjunctivitis can be caused by allergies, irritants, or infectious agents such as bacteria, viruses, or fungi. Infectious conjunctivitis is highly contagious and can spread rapidly among dogs.
Dry eye syndrome, also known as keratoconjunctivitis sicca (KCS), is another potential cause of watery eyes in dogs. Despite its name, dry eye syndrome occurs when the tear glands produce an insufficient amount of tears or the tears are of poor quality, leading to excessive tearing and discomfort. This condition can be caused by immune-mediated disorders, certain medications, or environmental factors such as smoke or dust.
In some cases, watery eyes in dogs may be a sign of a more serious underlying condition, such as glaucoma, corneal ulcers, or uveitis. Glaucoma is characterized by increased pressure within the eye, which can lead to excessive tearing and vision loss if left untreated. Corneal ulcers are open sores on the surface of the eye that can cause pain, squinting, and watery eyes. Uveitis is an inflammation of the uvea, the middle layer of the eye, which can also lead to excessive tearing and other symptoms.
To determine the underlying cause of watery eyes in a dog, a veterinarian will typically perform a thorough examination of the eye using specialized equipment such as a slit lamp or an ophthalmoscope. Additional tests may be recommended based on the initial findings, such as tear production tests to diagnose dry eye syndrome or imaging studies to evaluate the nasolacrimal ducts.
The appropriate treatment for watery eyes in dogs depends on the underlying cause. If the condition is caused by conjunctivitis, the veterinarian may prescribe antibiotics, antifungals, or anti-inflammatory medications, depending on the type of infection. In some cases, topical ointments or drops may be recommended to soothe the eye and promote healing.
If watery eyes are caused by dry eye syndrome, artificial tears or other lubricating eye drops may be prescribed to supplement the natural tears produced by the dog's tear glands. In severe cases, medications such as cyclosporine or tacrolimus may be recommended to stimulate tear production and reduce inflammation.
If a blocked nasolacrimal duct is the cause of watery eyes, the veterinarian may recommend flushing the ducts with saline solution to remove any obstructions. In some cases, surgery may be necessary to open or bypass the blocked ducts and restore proper tear drainage.
If watery eyes are a symptom of a more serious underlying condition such as glaucoma or uveitis, prompt treatment is essential to prevent permanent damage to the eye. Medications such as topical beta-blockers or carbonic anhydrase inhibitors may be prescribed to lower intraocular pressure and reduce inflammation. In severe cases, surgery may be required to drain excess fluid from the eye or remove damaged tissue.
In addition to medical treatment, it is essential to maintain good hygiene around the eyes to prevent further irritation or infection. This may include gently cleaning the area around the eye with a warm, damp cloth and using only products specifically designed for use on dogs' eyes.
If your dog has watery eyes, it is crucial to consult with a veterinarian as soon as possible. Prompt diagnosis and treatment can help prevent further discomfort or damage to the eye and ensure the best possible outcome for your pet.
