Bloodshot Eyes in Dogs

Like humans, dogs too can develop red or bloodshot eyes from time to time, due to varied reasons. In most of the cases, it can be due to some foreign particles like grass or small pieces of wood deposited in their eyes. Such particles can cause irritation and result in bloodshot eyes. If the condition lasts for an hour or so and then goes away, then it is not such a major concern. But, if bloodshot eyes is very frequent and it lasts for several hours to days, then it can be a symptom of some serious disease. This is particularly true, if both the eyes are affected and if it is accompanied by watery discharge.

What Causes Bloodshot Eyes in Dogs?
Foreign particles like grass, wood piece and debris getting trapped inside the eyes is the most common cause of bloodshot eyes in puppies and dogs, especially if only one eye is affected. An important feature of a dog's eye is, that there is a third eyelid which serves an important purpose, by protecting the eyes from foreign particles. However, the same feature makes them more susceptible to bloodshot eyes, whenever any foreign object gets trapped under this lid.

However, if both the eyes of your dog are bloodshot, then it can be a symptom of other dog health problems. More frequently, it can be conjunctivitis or inflammation of the conjunctiva of the eyes. Along with redness, there can be watery discharge from the eyes. Conjunctivitis can cause itchiness, for which you may observe your dog scratching his or her eyes. Another common cause of bloodshot eyes in dogs can be allergies. Redness of eyes can be a very common symptom of allergic reactions. More on dog allergies.

Like humans, dogs can also get glaucoma, which is associated with increase in pressure inside the eyeball. This can cause extensive damage to internal structure of the eye and lead to loss of vision or blindness, if not treated on time. Along with a dilated pupil, pain, a cloudy cornea and tearing, redness of eyes can be an indicator of glaucoma.

Keratoconjunctivitis sicca or dry eye is the name for the condition that is characterized by insufficient production of fluid or water in the tear glands, which is essential for lubrication of the eyes. The result of this fluid insufficiency in the eye can be a dry and red eye with a burning sensation. Apart from these, bloodshot eyes with dilated pupils can be a sign of hypertension or high blood pressure. A sudden and significant increase in blood pressure can lead to permanent blindness, if not treated. More on dog health and dog illnesses.

When to Seek Medical Attention?
Bloodshot eyes in dogs would require medical attention, if the condition is very frequent and the eyes have turned cloudy or gray with dilated pupils and there is a watery or purulent discharge from the eyes. In addition to these, if the eyes seem a bit bulged and the eyelids have become swollen or turned inwards/outwards, it is better to get them checked up by a veterinarian. Increased sensitivity to light and drooping eyes are some other symptoms that should not be neglected by the pet owners.

A veterinarian would diagnose the condition on the basis of several tests, in order to find out the exact cause of bloodshot eyes in dogs. The treatment would depend on the underlying causes. As for example, conjunctivitis would require the administration of antibiotics and specific eye drops for bloodshot eye cure. Similarly, for dry eyes, special eye drops as well as artificial tear are required. For glaucoma and high blood pressure, a number of medications and treatment options are available, depending on the severity of the condition. On the other hand, for allergies, the best treatment is to protect the dogs from the potential allergens.

Therefore, proper diagnosis can play a key role in detecting and treating the underlying cause of bloodshot eyes in dogs. In the meantime, you may help your dog by keeping the eyes clean by rinsing them properly. Be sure to use tissue to dislodge any object that is trapped inside their eye. You can also opt for Doggles in order to protect their eyes from debris and other foreign objects. But, if the condition does not improve even after taking all necessary precautions and dog care, then visit a veterinarian at the earliest.
