Trauma or Eye Injury

Trauma may occur when a sharp or blunt object has its force applied on the dog’s eye or when they strike the eye’s surface. In the case when there is no bleeding and the eyes only become red, the force only caused trauma without penetrating the eye.

It is also possible for sharp objects to connect forcefully with the eye thus causing injury in the form of abrasions and lacerations.

This is also commonly referred to as pink eye or red eye. The condition occurs when there is inflammation in the conjunctival tissue. This can be brought about by infections or foreign materials in the eyes of a dog. The condition results in swelling, redness as well as mucous or watery discharge in the eyes of a dog. In addition, the eyes become itchy. If it progresses without treatment it might make the eye mildly painful.


The eye is filled with a viscous fluid known as aqueous humor. This is usually regulated carefully to ensure that the eyeball remains in its proper shape. According to, “This happens from a very slow, but fairly continuous, exchange of fluid between the inner eye chambers and the blood in systemic circulation. This balance is disturbed in dogs with glaucoma, because aqueous humor is being produced faster than it can be removed, causing pressure to build up.”

If left untreated, the elevated pressure leads to the damage of the retina and causes degenerative changes in the optic nerve. This eventually leads to blindness.

Red eyes in dogs resulting from glaucoma will have additional symptoms such as different sized pupils, cloudy eyes, tearing and squinting. With time, vision problems may arise making the dog walk gingerly, have difficulty finding toys and bump into objects.

Although there are no known ways of preventing glaucoma, regular checks can give way to management before the condition progresses into blindness. Additionally, Dogs that only have one red eye as a result of glaucoma should be monitored closely so as to ensure that it is noticed at the onset to make management easy.
