Conjunctivitis in Dogs


The conjunctiva is the moist tissue that covers the front part of the eyeball and lines the eyelids. Breeds that tend to have allergic reactions or autoimmune skin diseases have the tendency to have more issues with swelling of the conjunctiva. They are likewise most likely to have dry eyes, the outcome of a disease in which the animal is allergic to substances in the environment, such as pollen, that would not normally cause illness. Otherwise, there does not appear to be a type preference for this disease.

Conjunctivitis, also known as pink eyes, can affects both dogs and felines.

Symptoms and Types

  • Squinting or spasmodic blinking (blephora).
  • Redness of the damp tissues of the eye.
  • Discharge from the eye( s); it might be clear or might include mucus and/or pus.
  • Swelling from fluid accumulation of the moist tissue covering the eyeball.
  • Follicle development; follicles are build-ups of lymphoid tissues located at the damp tissue surface of the eyelids, triggering a cobblestone appearance; lymphoid tissue includes lymphocytes, a type of white-blood cell that is associated with allergies and act in action to irritants.

Causes of Pink Eyes In Dogs


  • Primary condition– not secondary to other conditions, such as dry eye.
    Neonatal conjunctivitis: newborn inflammation of the wet tissues of the eye – accumulation of discharge, typically connected with a bacterial or viral infection; seen before the eyelids separate or open.


  • Canine distemper infection.


  • Allergies.
  • Follicular conjunctivitis.
  • Plasma-cell conjunctivitis– inflammation of the moist tissues of the eye identified by the existence of plasma cells, especially in German Shepherds.
  • Related to generalized (systemic) immune-mediated illness in which the body’s immune system attacks its own tissues.


  • Growths (unusual).
  • Lesions that appear to be cancer, but are not cancerous. Swelling of the border between the cornea (the clear part of the eye, situated in the front of the eyeball) and the sclera (the white part of the eye); identified by the presence of blemishes, it is most commonly found in collies and mixed collies, and generally looks like a pink mass.

Secondary to disease of the tissues surrounding the eye:

  • Absence of normal tear film (dry eye).
  • Lid diseases.
  • Lash illness.

Secondary to injury or environmental causes:

  • Foreign body in the wet tissues of the eye.
  • Inflammation from dust, chemicals, or eye medications.

Secondary to other eye illness:

  • Ulcerative keratitis.
  • Anterior uveitis.
  • Disease of the eye, where the pressure within the eye is increased; known as glaucoma.


The first thing your vet will search for is proof of other ocular (eye) illness. For instance, the disease might not be in the conjunctiva but in other parts of the eye. Your doctor will carry out a complete eye examination. Different techniques of evaluation might consist of a fluorescein stain, which is spread on the surface area of the eye to make scratches, ulcers, and foreign product stick out under light. This is to dismiss ulcerative keratitis. Foreign materials may likewise have gotten caught in the lids or eyelashes, so they will be analyzed thoroughly also. A test for glaucoma will be performed by determining pressures in the eye, and the nasal cavity may need to be flushed out to rule out disease there. If there is discharge from the eye a culture will be done to determine what the discharge consists of, since infection might be shown, and a biopsy of conjunctiva cells might be collected for microscopal evaluation. A skin test may likewise be conducted if skin allergies are presumed to be the cause.


There are lots of possible causes for this disease, and the course of treatment will be determined by the cause. For example, if there is a bacterial infection, your vet will most likely recommend an antibiotic ointment, and possibly antibiotic medication to be taken by mouth. An elimination diet might also be advised if dietary allergic reactions are thought– foods will be cut down to the minimum, or altered, and after that different foods will be slowly contributed to the regular diet to test whether the source of the reaction is food based. In many cases, surgery might be required to remove an obstruction in a duct. If cancer is the medical diagnosis, surgical removal of the tumor may be advised, followed by radiation therapy. Your veterinarian might advise cryotherapy, a therapy which uses cold application. In the most severe and severe cases, removal of the eyeball and surrounding tissues will have to be performed.

If inflammation exists, medications will be recommended depending upon the cause. Your vet will make these determinations and suggestions. When it comes to newborn conjunctivitis, your doctor will open the eyelids with fantastic care, drain the discharge, and treat the eyes with a topical antibiotic (Terramycin or other).


Living and Management

If the cause is an allergic reaction, you will have to try to avoid contact with whatever your animal is reacting to. To decrease the risk of spreading out a contagious disease, try not to expose your pet to other animals, specifically in concerns to the canine distemper infection.

If your doctor makes a medical diagnosis of food based allergies, you will have to follow the suggestions concerning diet. You might have to make a rigorous strategy to identify what foods, if any, are causing the irritation. You will need to take your pet for a veterinary recheck after 5 to 7 days.

If a big amount of discharge is noted, carefully clean the eyes before applying any ointment. If both options and ointments are recommended, apply the solutions first. If several solutions are recommended, wait several minutes in between the application of each. If the condition worsens and it appears that your family pet is not reacting to the treatment, or is even having an unfavorable reaction to the treatment, you will need to contact your vet immediately for advisement. An Elizabethan collar to secure the eyes from scratching or rubbing can be specifically handy for the recovery procedure.
