Causes of tear stains in dogs

1. When in a new environment, irritating substances in the air will make the dog feel uncomfortable and cause tears. Tears and secretions will leave traces of tear stains over time.

2. Entropion. Entropion is a common eye disease in dogs, where the eyelashes are inserted into the eyes. Pain, scratching, inability to open eyes, and tears are common.

3. The nasolacrimal duct is blocked. The dog’s tears are discharged through the nasolacrimal duct. If the nasolacrimal duct becomes infected for some reason, the nasolacrimal duct will be blocked. If tears cannot be drained properly, they will overflow at the corners of the eyes, causing tear stains.

4. Dacryoadenitis. When the lacrimal glands are infected, a large amount of abnormal eye secretions and tears will be discharged. The nasolacrimal ducts cannot be sorted out and the secreted tears cannot be discharged, which will lead to the outflow of tears. Over time, Tear stains may form.

5. High oil and high salt. High oil and high salt in the diet are the main reasons for serious tear stains in dogs. Therefore, when pet owners buy dog ​​food, they must pay attention to the salt content in the dog food. Salt can be increased appropriately, but it must not be eaten too much.
