Can Dogs Get Pink Eye? Understanding Canine Conjunctivitis
What Is Pink Eye in Dogs?
Pink eye, medically known as conjunctivitis, is an inflammation of the conjunctiva—the thin membrane that covers the white part of the eye and the inside of the eyelids. It’s more common than most dog owners realize, and it can show up in various forms:
- Allergic Conjunctivitis – triggered by allergens like pollen, dust, or mold
- Bacterial Conjunctivitis – caused by bacteria, often contagious
- Viral Conjunctivitis – spread through airborne viruses or direct contact
- Foreign Body-Related – due to dust, grass, or tiny debris irritating the eye
Is It Contagious?
The answer depends on the type. Bacterial and viral conjunctivitis are contagious and can spread to other pets. In rare cases, some bacteria can be transmitted to humans. Allergic and irritant-based conjunctivitis, however, are not contagious.
Knowing the cause can help you take proper precautions for your home and other pets.

- Clear, yellow, or green discharge
- Excessive blinking or squinting
- Puffy or swollen eyelids

You shouldn’t wait too long if you notice:

Always trust your gut. If your dog looks uncomfortable or the symptoms worsen quickly, a vet visit is the safest move.
