Why does a dog's eye stick together? - briefly
A dog's eyes may stick together due to the presence of mucus or pus, often caused by an infection or irritation in the eye. This condition is commonly referred to as ocular discharge and can be treated with proper veterinary care.
Why does a dog's eye stick together? - in detail
A dog's eyes can appear stuck together due to several reasons, primarily revolving around eye discharge and tear production. This phenomenon is often seen in breeds with prominent eyes or those prone to eye issues, such as Pugs, Shih Tzus, and Boston Terriers.
Firstly, dogs have a unique eyelid structure that helps distribute tears evenly across the cornea. However, when tear production is disrupted or excessively high, it can lead to crusting around the eyes. This discharge can be clear, yellowish, or greenish, depending on its cause.
One common reason for a dog's eye discharge is an infection or inflammation of the eye, known as conjunctivitis. Conjunctivitis can result from various factors, including allergies, foreign bodies in the eye, or viral and bacterial infections. In such cases, the eyes may appear red, swollen, and sticky with discharge.
Another cause could be a blocked tear duct, which prevents tears from draining properly. This can lead to excessive tearing and crusting around the eyes. Breeds with short noses (brachycephalic breeds) are particularly prone to this issue due to their facial structure.
Dry eye syndrome, or keratoconjunctivitis sicca, is another potential cause. This condition occurs when the tear glands do not produce enough tears, leading to a thick, sticky discharge that can make the eyes appear stuck together.
Lastly, certain medical conditions and medications can affect a dog's eye health, causing excessive tearing or discharge. For instance, systemic diseases like diabetes or kidney disease can impact tear production, while some drugs may have side effects that include changes in eye secretions.
If your dog's eyes appear stuck together, it is essential to consult with a veterinarian for proper diagnosis and treatment. While some causes may be minor and resolve on their own, others could indicate more serious health issues requiring prompt attention. Regular eye care and monitoring can help maintain your dog's ocular health and prevent potential problems from escalating.
