Red eyes in a dog
Causes of eye redness in a dog
The causes of red eyes in a dog can be of a different nature: heredity, infectious and non-infectious diseases, injuries, and so on. In addition, redness may be local or extensive, observed for a short period of time or for a long time, accompanied by concomitant symptoms, or be the only sign of pathology.
Infectious diseases causing eye redness
In this group of causes of red eyes are contagious diseases caused by viruses, bacteria, fungus.
Chlamydia Often occurs in a chronic form. The eyes are affected alternately. If untreated, uveitis can develop, which ultimately ends in blindness.
Viral diseases of puppies. Redness of the eyes, as a rule, is accompanied by diarrhea, vomiting, high body temperature and the body losing a large amount of fluid.
Toxoplasmosis. Untimely assistance rendered leads to the development of uveitis, as well as with chlamydia. Newborn dogs, as a rule, do not survive, and spontaneous abortions often occur in infected pregnant females.
Telaziosis. It is a parasitic disease; telazii spread by flies. Feeding on the dog’s eye secretions, the flies are introduced onto the mucous membrane of the larva. Redness of the eyes is accompanied by clouding, inflammation of the eyelids, conjunctiva, loss of vision.
Conjunctivitis. This is an inflammatory process in the connective membrane of the dog’s eye, which occurs for a variety of reasons. Viral or bacterial conjunctivitis is contagious to other animals and humans. Depending on the nature of the disease, redness of the eyes is accompanied by various concomitant symptoms.
Keratitis With this disease, the cornea becomes inflamed. As in the previous case, the pathology has a different nature. In addition to red eyes, the dog observed: increased secretion of lacrimal secretion, thickening of the eyelids, deposition of calcium salts, the formation of pus in the organs of vision.
Chumka. The dog’s eyes turn red at the same time as lung damage. In parallel, the lymph nodes increase, vomiting and diarrhea appear, the body temperature rises, the eyes fester. The disease can lead to the death of the pet.
Red eyes in a dog can be the result of non-communicable diseases and conditions.
Mechanical injury. It can be obtained in the process of fighting with another dog or cat; the dog may accidentally damage the eyes with a branch; seeds or other small objects can enter the organs of vision.
Inversion and inversion of the eyelids. In the first case, the hairs located on the eyelid irritate the cornea of the eye, which over time can lead to visual impairment and blindness. In the second – there is a prolapse of the mucous membrane to the outside, which provokes the penetration of infectious agents into it. Pathology is often genetically determined and observed, for example, in bulldogs, sharpei.
Blepharitis. Depending on the provoking factor (trauma, parasites and others), the disease can be infectious or not. Besides the fact that the dog has red eyes, they fester, watery, and stick together.
The prolapse of the third century. This is a pathological condition in which the blinking membrane (third eyelid, including the lacrimal gland) covers part of the dog’s eye in the form of a pinkish or red film. It prevents the closing of the eyes, causes itching, redness of the protein, provokes the penetration of infections and the development of inflammation. Most often transmitted genetically.
Diabetes. In diabetes, dogs may have red eyes due to spikes in blood glucose. In this case, blood vessels become thinner, damaged – they rupture and hemorrhage. Concomitant symptoms: dull hair, dry mucous membranes (including the eyes), palpitations, the animal drinks a lot.
Blockage of the lacrimal duct. It leads to the appearance of red eyes and frequent inflammatory processes.
High blood pressure. Causes overflow of blood vessels in the dog’s eyes with blood and their redness. Over time, it can cause visual impairment or loss of vision.
Malignant and benign tumors. Various tumors (bumps) can also cause red eyes, exerting a mechanical, hormonal or other effect on the organs of vision. In old age, dogs often form a third-century adenoma.
Allergic reaction. Red eyes are accompanied by itching of various intensities, swelling of the mucous membrane, copious secretion of lacrimal secretions, sneezing. Any irritant can act as an allergen – pollen, drugs, ingredients of feed mixtures, hygiene products.
Red eyes as heredity
In some cases, red eyes in a dog are normal. This occurs if the pet is an albino or belongs to one of the breeds genetically predisposed to reddening of the proteins of the organs of vision. These include the bulldog, cocker spaniel, Pekingese, pug, basset hound and others. In this case, it is not the redness itself that is inherited, but the diseases in which this occurs, for example, inflammation of the conjunctiva.
