What Causes a Dog Eye Infection?

    There are two main causes for eye infections in dogs are


As a result, when dog get scratches in eyes with his paws or any injury causing damage to the cornea (clear eye tissue), bacteria as an opportunistic microorganism start reproducing at a rapid rate. And it will end up in eye infection. Tears act as a self-rinsing solution and protect the eyes from being exposed to bacteria. By some fault, if tear production becomes less or something blocks partially or completely tear ducts, bacteria will develop a colony and cause an eye infection.


Some of the viruses such as distemper can cause an eye infection.  

Other causes than bacteria and viruses include scratches or injury to eye, irritants, dust, less production of tears and foreign bodies in eyes.

Conjunctivitis In Dogs

 Inflammation of conjunctiva is known as conjunctivitis in dogs. Conjunctivitis or pink eye in dogs is most common in dogs. It can be infectious or non-infectious (caused by trauma or injury). The Conjunctiva is a mucous membrane that lines the eyeball and third eyelid in dogs and performs a crucial role in making a barrier against foreign particles for the protection of the eye. When this membrane gets inflamed and becomes red causative agents like bacteria or virus get the opportunity to cause the infection. There are a variety of causes of conjunctivitis in dogs but allergy is a common one. Conjunctivitis in dogs can be a symptom of eye infection and even in some cases, the infection could be secondary to conjunctivitis in dogs. Infectious conjunctivitis in dogs is contagious but non-infectious conjunctivitis cannot be transmitted from one to other.
