# Dog Eye Discharge: When Should You Worry?


## Key Takeaways

- Yellow or green eye discharge in dogs is a strong indicator of infection, necessitating veterinary evaluation for appropriate antimicrobial therapy.
- Persistent or worsening eye discharge, regardless of color, warrants veterinary consultation to rule out underlying conditions such as allergies, blocked tear ducts, or ocular injury.
- Home care for mild eye discharge involves maintaining a calm environment, removing environmental hazards, and closely monitoring for systemic signs like appetite changes or lethargy.
- Emergency veterinary care is indicated for severe symptoms including respiratory distress, collapse, seizures, severe gastrointestinal upset, or signs of acute pain and immobility.
- Veterinarians utilize patient history, physical examination, and potentially diagnostic tests like lab work, imaging, or specific ocular tests to determine the etiology of eye discharge.
- Proactive measures such as keeping hair away from the eyes and scheduling veterinary exams for any colored discharge, squinting, cloudiness, or pain can help prevent complications.

**Eye discharge in a dog can be mild or serious depending on the pattern, timing, and other signs. It may involve local irritation, discomfort, stress, injury, stomach upset, skin changes, or another medical problem. Call your veterinarian when signs are persistent, severe, or worsening.**

## What symptoms or causes should I watch for?

- **Normal tearing:** Small amounts can collect near the eye.
- **Allergies:** Irritation can increase tearing.
- **Infection:** Yellow or green discharge may signal infection.
- **Blocked tear duct:** Drainage problems can stain fur.
- **Eye injury:** Scratches can cause discharge and pain.

## What can I safely do at home right now?

- **Keep your pet calm:** Use a quiet room and limit rough activity until you know what is happening.
- **Check the basics:** Look for appetite changes, water intake, bathroom habits, breathing, pain, and energy level.
- **Remove obvious risks:** Pick up unsafe food, plants, medication, trash, string, toys, or chemicals.
- **Record details:** Write down when it started, how often it happens, and what changed recently.
- **Call your vet:** A dog owner should ask for guidance if the sign continues or the pet seems unwell.

## When is this an emergency?

Go to an emergency veterinary clinic now if you notice:

- Trouble breathing, collapse, seizures, or severe weakness.
- Repeated vomiting, severe diarrhea, blood, or a swollen belly.
- Obvious pain, inability to walk normally, or crying when touched.
- Not eating, not drinking, or not urinating normally.
- Any rapidly worsening sign, especially in a puppy, kitten, senior pet, or chronically ill pet.

## What will my veterinarian check?

Your veterinarian will use the history and physical exam to narrow the cause. They may recommend lab work, urine testing, stool testing, imaging, skin or ear tests, or other diagnostics based on the sign.

## How can I reduce the risk next time?

Keep hair out of the eyes and schedule an exam for colored discharge, squinting, cloudiness, or pain.
