Dry eye syndrome, also known as keratoconjunctivitis sicca (KCS), is a condition that can affect dogs. The duration of symptoms and the healing time for dry eye can vary depending on the underlying cause and the effectiveness of treatment. In most cases, dogs with dry eye syndrome show improvement within 12 weeks, with many experiencing positive changes within the first 6 weeks of treatment. Adequate tear production is crucial for maintaining the health of the eyes, and once tear production is restored to normal levels, the dog's symptoms typically improve. Regular veterinary rechecks are important to monitor the progress of the treatment and ensure the dog's eye health is maintained. Rechecks are usually scheduled every 3-4 months after the tear production has been restored. These follow-up appointments help assess the dog's tear production, monitor any potential complications or relapses, and make any necessary adjustments to the treatment plan.
