What this condition is

Red eyes in dogs causes and when it is an emergency is a common concern among pet owners. This condition refers to the redness or inflammation of the tissues surrounding the eye, often involving the conjunctiva (the thin membrane covering the white part of the eye) or the sclera (the white outer layer of the eyeball).

Redness in the eyes may cause discomfort or irritation and is often associated with various underlying issues. These can develop gradually or appear suddenly, depending on the cause.

How it typically develops

• Allergies: Exposure to environmental irritants may cause mild redness and itching.
• Infections: Bacterial or viral infections can lead to inflammation and discharge.
• Injury or trauma: Physical damage to the eye or surrounding area may result in redness and swelling.
• Underlying health conditions: Certain systemic diseases or eye disorders may cause persistent redness.

Because red eyes can indicate a range of issues, veterinarians may recommend a thorough examination to determine the cause and appropriate treatment. Only a licensed veterinarian can diagnose and treat pets safely and effectively.

Common causes

Red eyes in dogs causes and when it is an emergency can vary widely. Redness in a dog’s eye is often associated with irritation, inflammation, or underlying health issues. Identifying the cause requires a thorough veterinary examination, as many conditions share similar signs.

Frequent causes

• Allergies: Environmental allergens such as pollen, dust, or smoke may cause eye redness and discomfort.
• Conjunctivitis: Inflammation of the conjunctiva, often due to infections, irritants, or allergies, is a common cause of red eyes.
• Injury or trauma: Scratches, foreign bodies, or blunt trauma can lead to redness and swelling.
• Dry eye (keratoconjunctivitis sicca): Reduced tear production may cause chronic redness and irritation.
• Glaucoma: Increased pressure inside the eye is often associated with redness and can be serious.
• Uveitis: Inflammation inside the eye may cause redness and discomfort and can be linked to systemic diseases.

Some causes are less common or have mixed origins, making diagnosis complex. Veterinarians may recommend diagnostic tests to determine the exact cause and appropriate treatment. If redness is accompanied by pain, vision changes, or discharge, it may be an emergency requiring prompt veterinary attention.

Typical signs and symptoms

Red eyes in dogs causes and when it is an emergency can vary depending on the underlying issue. Pet owners may notice a range of signs, some mild and others more serious, that indicate their dog’s eyes are affected.

Mild signs often include:

• Redness or pinkness of the eye whites
• Occasional tearing or watery discharge
• Slight squinting or blinking more than usual
• Light sensitivity or reluctance to open the eye fully

More serious signs that may require prompt veterinary attention include:

• Persistent or worsening redness
• Thick, coloured discharge (yellow, green, or white)
• Swelling around the eye
• Cloudiness or changes in the eye’s appearance
• Sudden vision changes or apparent pain

It is important to monitor any changes in your dog’s eyes and keep notes on what you observe. These details can help your veterinarian determine the cause and appropriate treatment. Remember, only a licensed veterinarian can diagnose and treat eye conditions safely and effectively.

When it is an emergency

Red eyes in dogs causes and when it is an emergency can be difficult to determine without professional evaluation. Some signs may indicate a serious problem requiring immediate veterinary attention.

Pet owners should seek urgent care if their dog shows any of the following red flag signs:

• Sudden onset of intense redness or swelling in one or both eyes
• Severe eye pain, such as squinting, pawing at the eye, or reluctance to open the eye
• Rapidly worsening symptoms over a few hours
• Discharge that is thick, yellow, green, or bloody
• Vision changes, such as bumping into objects or apparent blindness
• Trauma to the eye or head
• Signs of systemic illness, including lethargy, vomiting, or fever

These symptoms may cause permanent damage if not treated promptly. Veterinarians may recommend emergency evaluation to diagnose the underlying cause and initiate appropriate treatment. It is important to avoid self-diagnosing or delaying care when severe or sudden eye problems occur.

How veterinarians diagnose it

When a dog presents with red eyes, veterinarians begin by gathering a detailed history. This includes asking about the onset, duration, and any changes in the eye’s appearance or behaviour. They may also inquire about exposure to irritants, trauma, or other health issues.

A thorough physical examination follows, focusing on the eyes and surrounding structures. The veterinarian looks for signs such as discharge, swelling, or pain, which may help narrow down potential causes.

Common diagnostic tests

• Ophthalmic examination: Using specialized tools, the vet assesses the eye’s surface, pupil response, and internal structures.
• Fluorescein staining: This test helps detect corneal ulcers or scratches.
• Schirmer tear test: Measures tear production to identify dry eye conditions.
• Tonometry: Measures intraocular pressure to check for glaucoma.
• Blood work: May be recommended to evaluate overall health or detect underlying systemic diseases.
• Imaging: Techniques such as X-rays or ultrasound can help identify deeper eye or orbital problems.

Red eyes in dogs causes and when it is an emergency can vary widely. Only a licensed veterinarian can accurately diagnose the underlying issue and recommend appropriate treatment based on the individual pet’s condition.

Treatment options

When addressing red eyes in dogs causes and when it is an emergency, veterinarians may recommend a variety of treatment approaches depending on the underlying cause. It is important to understand that only a licensed veterinarian can determine the appropriate plan for each individual pet.

Medications

Treatment may involve the use of medications to reduce inflammation, control infection, or manage pain. These could include topical eye drops or ointments, as well as oral medications. The choice of medication and duration of treatment will vary based on the diagnosis.

Procedures

In some cases, procedures such as flushing the eye, removing foreign bodies, or performing minor surgery may be necessary to address the cause of redness and discomfort.

Dietary and home care

• Dietary changes might be suggested if an underlying systemic condition is suspected.
