Does your dog have permanent red or brown stains and crusty fur around their eyes? These are known as tear stains, and they can make an otherwise well-groomed, happy dog look a little sad and sorry!
Stains can also appear around the mouth, or on your pet’s legs or belly if they chew their fur often.
Causes of tear stains
Tears are supposed to be sucked up by the tear duct opening on the lower and upper eyelid and drained through the tear duct to the nose – that’s why you need to blow your nose when you cry! In dogs with tear staining on their face, the tears aren’t being directed to the nose and are instead spilling over onto the face, causing stains.
Some causes of the red tear stains associated with excessive tearing can include:
- Hairy caruncles – which is the term for extra hairs in the corner of the eye
- Eyelid Entropian – rolling inwards of the lower eyelid which is common in brachycephalic dogs such as Shihtzus and Pugs.
- Lazy tear ducts – where the tear duct doesn’t open or work properly.
- Yeast Infections – When the fur around the eyes or mouth is constantly damp it becomes a breeding ground for bacteria and yeast. One of the most common yeast infections is Ptyrosporin, which is also known as Red Yeast. This causes a deep reddish-brown stain and slight odour.
Bacteria – Minor bacterial infections in the tear ducts, or blocked or lazy tear ducts may cause excess tearing and staining as mentioned further above.
Allergens – Dogs are susceptible to similar allergens as humans, such as certain plants, food preservatives, ingredients in shampoos and other environmental factors.
- Genetics – As mentioned already, some breeds are more prone to tear stains due to breed related issues.
Vet treatment for underlying cause is a must
Depending on the severity of the underlying cause of your dog’s tear stains, surgery may be required to improve drainage. In milder cases, maintenance will suffice to keep their face clean and dry.
Less commonly, some dogs are born without a tear duct opening (I often see this in Cocker Spaniels) and surgery is required to correct the problem.
Another cause for tear staining may be overproduction of tears if something is irritating their eye, like pollen, wind and extra eyelashes (known as Dstichia).
If your dog has a mucky ocular discharge and especially if they are also squinting or rubbing their eye then take them to the vet ASAP to avoid any threat to vision.
Causes for this could include allergic conjunctivitis, dry eye, inflammation inside the eye (uveitis) and corneal ulcers.
Managing tear stains at home
When it comes to managing tear stains it’s important to keep the fur around your dog’s eyes short and combed out, along with using a safe and natural topical solution each day to wipe and then dry them.
Keeping the area clean and dry helps to prevent secondary bacterial and fungal infections.
Never use products containing peroxide or tooth whitening gel as these can irritate your dog’s eyes, instead opting for an effective, natural solution to help keep those stains at bay.
