Eyes are your dog’s vessels to life and are made up of several parts. Each of these parts has extremely important functions and when attacked, these functions may break down.
The Anterior chamber of your dog’s eye is the area that is located behind the cornea and is filled with a liquid substance called aqueous humor.
It is a thick watery substance that actually sets between the lens and the cornea.
It main function is to inflate the globe of the eye itself.
The ciliary body is the structure that produces this fluid and is the front portion of the eye.
The Conjunctiva is the lining of the eyelids as well as the thin membrane which covers the white part of the eye known as the Sclera.
It helps to lubricate your dog’s eye as well as assisting in the production of mucus and the tearing.
The Cornea is the clear covering of the front of the eye and the Iris is the colored part of the organ that helps to control the amount of light that enters into your pet’s eyes.
The Lens of your dog’s eyes is the portion that focuses light on the Retina and the pupil is the actual opening of the eye that looks like a dark circle.
Your dog has one more part of the eye that is very interesting, the third eyelid.
It is translucent and can be drawn across the eye both for protection and for moisture.
It is also called the nictitating membrane and is totally different the human eyelids as they can move horizontally.
Dog’s eyes are very sensitive, but turning red is not a normal function.
This is an inflammation of the cornea that is most often caused by a virus, bacteria, some type of an allergy, a constant irritation, or could even be caused by a traumatic situation.
It is a common condition and is found in all breeds; and if becomes chronic, it is than called Pannus, and this eye condition is only found in dogs.

It will make your dog’s squint as the pupil is constricted which may develop into a lot of tearing of the eyes.
The Iris will appear swollen and the cornea may become very cloudy.
In severe situations it could result in a contraction of the pupil due to increased protein that is being sent to the eye as a natural defense.
If left untreated, it could lead to glaucoma or cataracts. In smaller breeds of dogs this can also lead to secondary lens luxation.
Treating this eye infection will consist of anti-inflammatory medications to help to dilate the eyes as well as reducing the pain.
This is a condition to take very serious as cancer could be the underlying cause of the symptom in red eyes in dogs.
This condition is well known as pink eye, and it is a potential cause of red eyes in dogs.

With this eye condition the pupils will remain normal in size, but there will be a lot of discharge because of the infection.
Treatment will consist of antibiotics depending on the actual cause as well as keeping the eyes and eyelids clean.
Glaucoma is a very serious eye condition in your dog as what is happening is an increased pressure is being put on the eyes and causing them to turn a reddish tint.
It is caused by the aqueous humor not allowing the increased fluid to drain from your pet’s eyes.
Additional fluid is being produced but because it is not draining, it becomes very similar to a water balloon.
This is an emergency situation in your dog as this balloon effect will eventually burst. When it does rupture, it damages to the eyes internal structures.
They most likely will be either crushed or in very severe cases, totally displaced.
Treatment for these red eyes in dogs condition will be antibiotics to reduce the pressure around the eye as well as reducing the extra fluid that have been produced.
In most all cases, dilation of the pupil will also be necessary.
