A dog's sclera may appear red due to irritation, allergies, infections, or trauma, and it’s essential to consult a veterinarian for an accurate diagnosis and treatment.
Why are my dog's sclera red? - in detail
A red sclera in your dog can indicate various underlying issues, ranging from mild irritations to more serious health conditions. The sclera, the white outer layer of the eye, may appear red due to inflammation, injury, or infection. Common causes include conjunctivitis, which is an inflammation of the conjunctiva, the thin membrane covering the sclera and inner eyelids. This condition can result from allergies, bacterial or viral infections, or exposure to irritants like dust or chemicals. Another potential cause is uveitis, an inflammation of the uvea, the middle layer of the eye, which can lead to redness, pain, and sensitivity to light. Trauma, such as scratches or foreign objects in the eye, can also cause redness, as can glaucoma, a condition characterized by increased pressure within the eye that can damage the optic nerve. Additionally, systemic conditions like autoimmune diseases or blood clotting disorders may manifest with ocular symptoms, including a red sclera. Environmental factors, such as dry air or prolonged exposure to wind, can also contribute to eye irritation and redness. It’s crucial to monitor your dog for other symptoms, such as discharge, squinting, pawing at the eye, or changes in behavior, as these can provide clues to the underlying issue. If the redness persists or is accompanied by other concerning signs, consult a veterinarian promptly. Early diagnosis and treatment are essential to prevent complications and ensure your dog’s eye health.
