What is the appropriate course of action if you notice dry eye in a dog?

Noticing dry eye in a dog, also known as keratoconjunctivitis sicca, is a significant concern that warrants attention and care. Consulting a veterinarian for treatment options is the most appropriate course of action because a professional can determine the underlying cause of the dry eye and recommend proper treatments. The veterinarian may prescribe medications, such as corticosteroids or tear stimulants, or suggest other therapies depending on the severity of the condition.

Veterinarians have the expertise to assess the specific needs of the dog, including potential risks or complications associated with untreated dry eye. This condition, if left unaddressed, can lead to discomfort and serious damage to the eye, potentially resulting in vision loss. Therefore, seeking professional guidance ensures that the dog's health and well-being are prioritized.

The other responses do not adequately address the seriousness of the condition. Ignoring dry eye is misguided, as it can worsen over time. Applying eye drops without consulting a vet can lead to improper treatment, and making drastic dietary changes may not address the root cause of the issue at all. Thus, the optimal and responsible approach is to seek veterinary advice.
