Symptoms of Conjunctivitis:
- Redness of the conjunctiva
- Excessive tearing
- Eye discharge (clear, yellow, or green)
- Squinting
- Rubbing the eyes with paws
H3: Dry Eye (Keratoconjunctivitis Sicca)
Dry eye, a condition characterized by insufficient tear production, can also lead to bloodshot eyes in dogs.
Symptoms of Dry Eye:
- Excessive blinking
- Redness and inflammation
- Thick, sticky discharge
- Cloudiness of the cornea (the transparent outer layer of the eye)
H3: Corneal Ulcers
Corneal ulcers are open sores on the cornea. These ulcers can cause pain, redness, and excessive tearing.
Symptoms of Corneal Ulcers:
- Severe pain and discomfort
- Squinting
- Sensitivity to light

FAQ
Q1: What causes bloodshot eyes in dogs?
Bloodshot eyes in dogs, also known as conjunctivitis, can be caused by various factors, including allergies, infections, foreign objects, dry eye, and even certain medications. Allergies can trigger inflammation and blood vessel dilation in the eye, leading to redness. Infections, bacterial or viral, can also cause inflammation and redness. Foreign objects lodged in the eye can irritate the surface, causing blood vessels to dilate. Dry eye, a condition where the tear film is insufficient, can lead to irritation and redness. Certain medications, like those used to treat heartworm, can also have bloodshot eyes as a side effect.
It’s essential to determine the underlying cause of bloodshot eyes to provide appropriate treatment. If you notice any changes in your dog’s eyes, it’s best to consult with your veterinarian for a proper diagnosis and treatment plan.
Q2: Is a bloodshot eye always a serious problem?
While bloodshot eyes can be a sign of a serious issue, they are not always a cause for major concern. In many cases, they are caused by minor irritations or allergies and resolve on their own with minimal intervention. However, if the redness persists, worsens, or is accompanied by other symptoms like discharge, swelling, squinting, or pawing at the eye, it’s crucial to seek veterinary attention.
These additional symptoms could indicate a more serious condition like an infection, corneal ulcer, or glaucoma. Prompt diagnosis and treatment are essential to prevent vision loss and other complications.
