How to Tell If Your Dog Has Conjunctivitis
Conjunctivitis, commonly known as pink eye, is an eye condition that can affect dogs just like humans. It involves the inflammation of the conjunctiva—the moist tissue covering the eye and the inside of the eyelids. Recognizing the signs early can lead to prompt treatment and prevent further discomfort for your dog.
Common Signs of Conjunctivitis in Dogs
If you're wondering whether your furry friend might be suffering from conjunctivitis, look out for these typical symptoms:
- Red or bloodshot eyes
- Swelling of the eyelids or conjunctiva
- Excessive tearing or watery discharge
- Thick mucus-like yellow or green discharge
- Frequent squinting or blinking
- Rubbing eyes with paws or against surfaces
- Light sensitivity
What Causes Canine Conjunctivitis?
There are several potential causes of conjunctivitis in dogs. Identifying the underlying source helps guide treatment. Major causes include:
- Allergies – pollen, dust, mold, or household chemicals
- Infections – bacterial, viral, or fungal
- Foreign bodies – dirt, hair, or grass in the eye
- Injury or trauma to the eye area
- Dry eye (Keratoconjunctivitis sicca) – reduced tear production
- Irritants – smoke, shampoos, or cleaning products
- Underlying diseases – autoimmune disorders or tumors
Is Conjunctivitis Contagious to Other Pets or Humans?
Bacterial or viral conjunctivitis can sometimes be contagious to other dogs or, though rarely, to humans and other pets. Keep your dog’s items separated and wash hands after treating their eyes if conjunctivitis is suspected to be infectious.
Steps for Diagnosing Conjunctivitis
You should consult a veterinarian if you observe symptoms. The vet may perform:
- Physical examination of the eye
- Fluorescein stain test to check for corneal damage
- Tear production test if dry eye is suspected
- Swab and culture to identify infections
Treatment Options
Treatment depends on the cause:
- Antibiotic or antiviral eye drops or ointments for infections
- Anti-inflammatory medications to reduce swelling and pain
- Artificial tears for dry eye
- Allergy treatments or antihistamines
- Removal of foreign objects
Do not use human eye drops without veterinary approval—they may worsen the condition.
Preventing Conjunctivitis in Dogs
Some ways to help prevent your dog from developing this eye condition include:
- Regular eye cleaning with a vet-approved solution
- Keep your dog’s environment clean and dust-free
- Routine vet checkups and prompt allergy management
- Protect eyes during activities that may cause irritation (e.g., car rides or windy walks)
When to See the Vet Immediately
Seek urgent veterinary care if your dog’s eye problem:
- Appears suddenly and severely
- Includes thick discharge
- Comes with vision changes or eye cloudiness
- Persists beyond 2–3 days of home care
Conclusion
Early detection and treatment of conjunctivitis can prevent more serious complications and keep your dog comfortable and healthy. Keep a close eye on your dog’s behaviors and physical signs—when in doubt, always contact your veterinarian. With prompt action, most cases of dog conjunctivitis can be resolved quickly and completely.
