Why do dogs' eyes stick together? - briefly
Dogs' eyes can stick together due to the presence of mucus or pus in their tear ducts, which can dry out and form crusts. This condition is commonly known as "sleepy eye" or "cherry eye." Regular cleaning and veterinary care can help manage and prevent this issue.
Why do dogs' eyes stick together? - in detail
Dogs, like many other animals, produce tears to keep their eyes lubricated and clean. However, unlike humans who have tear ducts that drain excess tears into the nasal cavity, dogs do not have this efficient system. Instead, their tears flow over the edge of the eyelids and onto the fur around the eye area. This is why you may often see dried tear stains on a dog's face, particularly around the eyes and muzzle.
The primary reason why dog eyes stick together is due to the accumulation of these tears. When a dog sleeps or rests with its eyes closed, the tears that are not absorbed by the eye or evaporated can cause the eyelids to adhere to each other. This is more common in breeds with prominent eyes and excessive tearing, such as Pugs, Shih Tzus, and Maltese.
Several factors can contribute to this issue:
- Eyelid Anatomy: Some dogs have anatomical features that make their eyelids more prone to sticking together. For example, breeds with inverted or rolled eyelids (entropion) may experience irritation and increased tearing, leading to the eyes sticking together.
- Diet: A diet rich in omega-6 fatty acids can contribute to excessive tearing. Conversely, a balanced diet that includes omega-3 fatty acids can help reduce tear production.
- Health Issues: Various health conditions, such as allergies, eye infections, or dental problems, can cause increased tearing and result in the eyes sticking together.
- Hygiene: Poor hygiene around the eye area can also lead to this problem. Accumulated debris and discharge can irritate the eyes and increase tear production.
To prevent a dog's eyes from sticking together, owners can take several precautions:
- Regularly clean the area around the eyes with a damp cloth or specialized wipes designed for dogs.
- Maintain a balanced diet that supports eye health.
- Keep the dog’s fur trimmed around the eyes to reduce the accumulation of tears and prevent irritation.
- Consult a veterinarian if excessive tearing persists, as it could indicate an underlying health issue that requires treatment.
By understanding the reasons behind this common occurrence and taking appropriate measures, owners can help ensure their dogs' eye comfort and overall well-being.
