Record four things
- One eye or both.
- When it began and whether it is worsening over hours.
- Whether the dog squints, rubs the face or avoids light.
- What the discharge looks like: clear, mucoid, yellow, green or bloody.
Urgent warning signs
- The eye is closed or clearly painful.
- Sudden cloudiness, a blue appearance or trauma.
- Unequal pupils, disorientation or suspected vision loss.
- Severe swelling, blood or chemical exposure.
What to do before travelling to the clinic
Prevent rubbing and use a protective collar if needed. Do not reuse old drops: a steroid product can be dangerous when the cornea is damaged. For chemical exposure, call a clinic immediately and follow its rinsing instructions.
Screening is not a substitute for urgent care
An eye examination for a breeding dog helps identify inherited and acquired changes. A previous certificate does not rule out a new injury, ulcer or inflammation today.
