The excessive tearing in dogs has several origins. A consultation with the veterinarian is essential when a dog’s eyes have been crying profusely, for a few days or suddenly, and a fortiori if there is any discharge of pus. It is essential to identify the cause for the animal to benefit from a perfectly adapted treatment. Self-medication should be avoided absolutely because it can lead to serious complications.
Excessive tearing in dogs: the causes
It is a frequent phenomenon in certain dog breeds, in this case in brachycephalic dogs, namely those who have a crushed nose such as for example the Pekingese, the Boston Terrier, the Bulldog (English, French), the Boxer or the Shar-pei and others. The flow of tears is disadvantaged in these dogs because of the shape of their skull. In other breeds, such as the Poodle, the problem is often due to recurring dysfunction of the lacrymonasal system. But all the dogs, of any race, may one day have unusually weeping eyes.
For some, for a few days, tears have escaped from the inner corner of the eyes and leave traces of a color reminiscent of rust on the hairs located at the level of the inner corner of the eye and sometimes up to the corner of the muzzle. . For others, the tears flow into the lacrimal sac connected by the tear duct to the nasal cavity. There are many causes excessive tearing in dogs, namely:
- The projection of a chemical in an eye,
- Exposure to a strong wind, an icy wind or even smoke (garden fire, barbecue, etc.),
- A scratch in the eye,
- A foreign body such as a spikelet for example,
- Conjunctivitis, whatever its origin, namely: viral, parasitic, bacterial, fungal, mechanical,
- An allergy,
- A uveitis, inflammation that affects the inner lining of an eye,
- A blepharitisinflammation of the eyelids
- Narrowing or complete obstruction of the tear ducts for any of the following reasons:
- Sinus disease,
- A tumor,
- A mucous plug,
- A wound and sometimes the scar left by an old wound,
- A malformation likeentropion, a term which designates the rolling of an eyelid inwards and which, as a result, clogs the tear point. It can also be a ectropion. In this case the eyelid rolls up outwards.
- Local irritation which is generally favored by:
- A skin growth that develops either on an eyelid or on the cornea. We are then in the presence of a dermoid palpebral or corneal dermoid
- Some poorly planted eyelashes, we then speak of ectopic eyelashes. They rub on the cornea which can sometimes ulcerate it. The resulting eye condition is called distichiasis.
- Too long hairs located near the eyes and causing damage to the conjunctiva and cornea. We then speak of trichiasis.
It is legitimate for the owner of the dog to be concerned, especially since the tears may contain blood (they are then pink) and symptoms may be associated with the excessive flow of tears, namely:
- Pus in one or both eyes
- The weeping eye and nose are unusually hot, but also:
- Repeated infections in the eyes.
It should also be noted that during these episodes, the dog sees trouble, but the owner does not realize it.
My dog has weeping eyes: how can I treat him?
Excessive tearing can be uncomfortable for the dog in addition to being unsightly. And in the absence of treatment, the animal risks eye inflammation and an skin infection. The consequences can therefore be more difficult to treat. It is essential to consult a veterinarian so that the problem causing this excessive tearing can be clearly identified.
The practitioner adapts the treatment protocol on a case-by-case basis. He can therefore use:
- Clipping the hair around the eyes,
- Probing the tear ducts, especially when the flow of tears is chronic,
- Topical and / or systemic treatment if the dog has an infection,
- Surgical treatment allowing:
- Excision of a mucous plug,
- The correction of a malformation such as entropion or ectropion,
- Repositioning of the eyelashes …
In the presence of a very specific problem, the practitioner can refer his patient to a veterinarian specializing in ophthalmology.
Finally, a daily cleaning of the affected area is advised. For this, you must use only a suitable lotion, such as chamomile or blueberry hydrosol or physiological serum which is soaked in a sterile compress. The gesture must be delicate.
The owner noting that his dog has weeping eyes, must in no case decide without medical advice to use eye drops or, more generally, to opt for self-medication of any type whatsoever because the consequences can be serious for the animal if the treatment is unsuitable.
