Have you noticed that your dog's eyes are teary or seem to have excess drainage? Excessive tearing, or epiphora, is a common issue seen in dogs. It may develop into a discharge that is clear, white, yellow, or even green in color. When a dog's eyes are draining and teary, it's usually a sign of an eye problem. There are a variety of possible causes for eye drainage and excessive tearing in dogs. In most cases, the dog will need some kind of human intervention to help. In some cases, medical attention is needed.
There are numerous eye problems that can occur in dogs. Many of these will cause excess tearing and drainage. Some eye issues are more serious than others.
Short-faced and brachycephalic breeds like Shih Tzus, Cocker Spaniels, Maltese, Bulldogs, and Pugs are especially prone to eye discharge because of their face shape. Many small dog breeds also have excessive tearing. Moisture can collect in the facial and nasal skin folds of some breeds, providing an ideal environment for bacterial overgrowth. This may lead to infections if not kept clean and dry.
Dogs can develop bacterial, viral, or fungal infections in their eye. This may be brought on by an irritant that got into the eye. It could also be transmitted by other animals. Once an eye infection is present, the dog will need to be treated with the appropriate prescription medications. This often involves applying drops or ointment to the eyes a few times a day.
If your dog has environmental allergies, it may make the eyes red and weepy. This is similar to the way hay fever affects humans. Antihistamine medications can sometimes help.
Anything that irritates the eye can result in excessive tearing and eye drainage. Minor irritants or allergens may cause a dog to rub at his eyes, furthering the irritation and inflammation. More serious eye injuries can occur if something sharp scratches the eye, like an animal claw or object. If you suspect your dog has an eye injury, be sure to bring him to the vet as soon as possible.
The nasolacrimal duct drains tears from the eyes out through the nose. A blocked nasolacrimal duct causes normal tears to overflow from the eye rather than draining like usual.
Also called dry eye, this condition is characterized by an underproduction of tears. This causes irritation to the eye because of the lack of lubrication. Very dry eyes can result in thick, sticky discharge, infections, pain, and visual issues. Veterinary intervention is essential to treat this issue.
An abrasion on the cornea can occur secondary to trauma, infection, or another eye condition. Without treatment, corneal ulcers can become very serious, even resulting in loss of vision or even the eye itself.
This condition causes abnormal growth of eyelashes. Hairs grow along the eyelid and toward the eye itself, causing irritation.
This condition causes the eyelid to roll inward. The lid and eyelashes rub on the cornea, leading to irritation.
It's important to take action at the first sign of an eye problem. If the drainage is mild to moderate and your dog's eyes are not red or swollen, then it's appropriate to watch and wait. Keep the area around the eyes as clean and dry as possible. If the drainage is not getting better on its own, or you notice other signs of eye problems, it is important to seek veterinary help.
Contact your vet if you notice:
Eye issues can very quickly turn serious if not treated by a veterinarian. Do not delay or your dog may end up with permanent eye problems.
First, your veterinarian will get a history from you, asking questions about lifestyle, past health concerns, and the current signs you have noticed. Next, a veterinary exam will be done. Your veterinarian will examine your dog's eyes with a light.
A "tear test" may be done to check your dog's tear production. This involves placing special paper strips in the eyes and timing how long it takes the tears to reach a line on the paper strip.
Next, a painless, harmless eye dye (called fluorescein stain) may be applied to look for abrasions to the cornea (ulcers). Other eye tests may be recommended depending on the findings of the exam and preliminary tests.
Your vet will recommend treatment based on the diagnosis. This often involves the use of medicated eye ointment or drops that you apply at home several times a day. Oral medications are also sometimes prescribed.
Most dogs will need to wear an e-collar (the "cone" or lampshade worn around the neck). This collar will keep your dog from pawing at the eyes and rubbing his face. Do not remove this unless your vet says it is okay. Further irritation can cause serious eye damage.
Surgical treatment may be needed in some cases, especially if the cause is due to entropion or another anatomical abnormality.In complicated cases, your vet may refer you to a veterinary ophthalmologist.
If your dog has no underlying health issues, there's a good chance you can prevent excessive tearing and the resulting odor by following a few simple procedures:
