The dog's eyes turn sour: causes, symptoms, treatment

The complex of daily pet care includes examination of all mucous membranes: eyes, nose and mouth. Inexperienced owners are very worried when the dog's eyes turn sour and this anxiety should not be called redundant. Sour eyes can indicate the development of another and more serious ailment, but in order to understand what to do, you need to identify the causes of poor health of the pet.

The reasons

Timely revealed ailment is easier to cure without serious consequences. It should be understood that even harmless inflammation of the mucous membranes of the eye can lead to loss of vision, and if a secondary infection joins, then the scale of the consequences is completely unpredictable.

To begin with, let's figure out what is "sour" in your concept? As practice shows, the owners describe different situations with this term:

  • Viscous, opaque discharge without a pungent odor accumulates in the corners of the eyes of dogs.
  • In the corners and on the lower eyelids of the dog, a thick, stretching, transparent or slightly unclear liquid is collected.
  • The eyelids of the dog are covered with pus (or secretions similar to pus). After sleep, the eyelids stick together and it is difficult for the pet to open its eyes.

The third paragraph indicates an already developed conjunctivitis, a contagious and non-dangerous disease, unless of course timely treatment is started.

The first and second type of manifestation may indicate a very wide range of reasons:

  • Injury - during walks, the dog can injure the mucous membranes, especially if the four-legged one likes to run in bushy terrain.
  • Foreign body contact - when playing in sand, loose soil, keeping puppies in straw or sawdust, the probability of damage to the mucous membranes by small foreign objects is high.
  • Gum and tooth diseases - in the case of inflammation of the mucous membranes of the mouth, the dog may experience increased separation of mucus from the nose and eyes.
  • Allergy - an immunity reaction, expressed by itching, a general deterioration of the condition, active work of the mucous membranes of the mouth, eyes and nose.
  • Infectious lesion or debilitated condition - with any barely begun illness or elementary hypothermia, the mucous membranes of the body begin to work more actively, which can be expressed by copious discharge from the eyes.
  • Bacterial lesion - with damage to streptococci and staphylococci in dogs, there is an acute development of general malaise, copious discharge from the eyes and photophobia.
  • Viral disease - plague of carnivores, rabies, enteritis and other viral ailments, accompanied by abundant discharge from the eyes or conjunctivitis.
  • Worming - with severe invasion, whitish discharge is often observed, which dry and glue the eyelids.
  • Features of the structure of the eye - for some dogs, more active work of the mucous membranes of the eyes is characteristic due to pedigree characteristics or physiological predisposition. This is not necessarily about defects, for example, there are breeds that are generally prone to conjunctivitis.


Reddened, swollen eyelids and purulent discharge from the eyes are clear signs of conjunctivitis. The ailment develops and becomes apparent when the conjunctiva becomes strongly inflamed in the four-legged (the third eyelid looks like a sac). Although conjunctivitis is divided into types and, sometimes even treated differently, there is no single reason for this ailment. There are many reasons for the development of inflammation, and usually, they are associated either with microorganisms, or with the ingestion of foreign objects, including injuries.

Note! In more than half of cases, conjunctivitis manifests itself as a symptom, and not an independent ailment.

The experience of veterinarians shows that one of the most common causes of illness is vital activity of microorganisms. The mucous membrane covering the eyes is constantly in contact with the environment and is attacked by germs. While the dog is healthy, this process does not bring any inconvenience, but as soon as the immune defense has weakened, the inflammatory process begins. The conjunctiva is a sac in which ideal conditions are created for the reproduction of bacteria. While the immune system is working at full strength, bacteria that have fallen into the conjunctiva die before they can multiply.

Conjunctivitis - the disease is very common, in the eyes of an experienced dog breeder, it has become harmless, since it is quickly treated. Nevertheless, the disease is usually divided into several types, since its course and consequences may differ.

Owners of breeds prone to conjunctival inflammation need to pay special attention to dog eye care. It is believed that large dogs are affected, especially from the dog family, animals with "wet" centuries and miniature tailed dogs with a potentially weak immune system. If you notice that the pet rubs its face with its paws, cannot fully open the eyelids or the mucous membranes of the eyes are swollen, the dog can be treated at home. Naturally, if you are faced with the disease for the first time, it is better to consult a veterinarian, but rubbing your eyes (eliminating the source of infection) will not hurt.

Acute conjunctivitis - The simplest and most complex view at the same time. It develops rapidly, with timely help, the symptoms are almost completely eliminated within 2-3 days. The animal can be considered fully recovered, if the disease has not recurred within 21 days, active treatment continues for 7-10 days.

Catarrhal conjunctivitis - it can be called a lightened acute form, the symptoms are identical, treatment lasts up to 7 days, full recovery occurs on the 14-15th day.

Chronic conjunctivitis - also a variety of acute form, which is not alleviated by symptomatic treatment for 4 or more weeks.

Purulent conjunctivitis - One of the varieties of the acute course of the disease, accompanied by the release of yellow or green pus from the conjunctiva. At first, pus may be white (sterile), but inflammation is aggravated during the day. Often purulent conjunctivitis is a consequence of a more serious ophthalmic ailment, for example, keratitis.

Follicular conjunctivitis - the disease occurs due to severe irritation of the mucous membranes of the eyes. Most often, the owner notices follicular conjunctivitis in fact, and cannot even suggest the reasons for its development. The difficulty is that this form of the disease occurs even if irritation is caused by smoke, strong winds, exhaust fumes, etc. Further, inflammation extends to the follicles, which, in turn, swell and irritate the cornea of ​​the eye.

Important! A particular symptom by which follicular conjunctivitis can be distinguished is the bright pink or raspberry color of the mucous membranes of the eyes.

Symptomatic conjunctivitis - Very often, inflammation of the mucous membranes of the eyes occurs due to endogenous processes that occur secretly. It has been observed that with viral diseases such as pyroplasmosis and hepatitis, the eyes become very sour, and local treatment does not help.

Conjunctivitis may indicate an injury that has gone unnoticed.. Very often, eyes become inflamed in dogs who like to dig earth or sand - dust and dirt get into their eyes. After walking on tall grass during flowering, conjunctivitis may develop as a result of irritation to pollen or spores. Even air, more precisely, its chemical components, can lead to the development of inflammation.

Allergic conjunctivitis - irritation of the mucous membrane of the eye occurs as a reaction of the immune system to any allergen. The main difference from symptomatic conjunctivitis is that the dog not only sour eyes, but also active lacrimation.

Self conjunctivitis - This is a kind of ailment, the cause of which could not be established. They are inclined to diagnose this type if periodically the dog sour one eye or the occurrence of conjunctivitis cannot be associated with common causes.

Conjunctivitis treatment

Having no experience in keeping and treating animals, it is better to consult a doctor. So you can make sure that conjunctivitis is not the cause of the viral disease, and do not miss the time to help. You can postpone a visit to the doctor until the dogs can open their eyes after sleep, if the eyelids begin to stick together, the pus is not sterile, that is, the infection joined the inflammation.

Ideally, a so-called flush is taken from the dog’s sore eyes and bacteriological culture is performed. If no pathogens are found, the veterinarian suggests an allergic form of conjunctivitis and prescribes antihistamines. In the absence of obvious positive dynamics, the animal is assigned a screening for stealth developing ailments. Usually, blood is taken from the dog, and if necessary, an ultrasound and X-ray examination is performed.

If a purulent form of conjunctivitis is detected in most cases, treatment is carried out with broad-spectrum antibiotics. If the pathogen is detected by flushing, treatment is carried out with drugs with a narrow spectrum of action. In the clinic, as a first aid, the eyes are rinsed abundantly with a weak solution of furatsilina, after, the dogs are prescribed treatment.

Tip: if you decide to rinse the dog’s eyes on your own, you need to use a solution of low concentration, not more than 1 part of furatsilin to 5000 parts of pure (boiled, distilled) water. It is better to buy a ready-made, low concentrated solution.

Without preliminary analyzes, treatment is carried out according to the same scheme:

  • Maintaining cleanliness.
  • Removal of irritation.
  • Local treatment with drops.

Depending on the degree of inflammation, financial capabilities and personal preferences, the doctor may prescribe chloramphenicol drops, tobrex, cyprovet and others. The choice of the drug is based on the width of the spectrum of its action, that is, the more and more diverse the hostile bacteria are able to destroy the active substance, the better. Most drops from the middle price segment have not only a therapeutic, but also anti-edematous effect.

The veterinarian prescribes the course of treatment with drops, and if you treat the animal yourself, it is better to consult a doctor by phone. Usually, 1-2 drops are prescribed in each eye at least 4 times a day. The duration of the course takes from 5 days to 2 weeks. The course does not stop, even if all visible symptoms have disappeared.

Note! All drugs have side effects. Treatment of animal allergy sufferers is best done under the strict supervision of a doctor, since a dog may show intolerance to the components of the drug.

Suppose you do not have the opportunity to see a doctor in the near future, how to alleviate the condition of the dog in this case? To start rinse eyes according to the scheme described above. As often as possible, but at least 2 times a day, the eyelids of the dog should be wiped with tightly brewed black tea. If you are sure that the dog is not allergic, instead of tea, it is better to use a decoction of chamomile or calendula. Keep in mind that inflamed eyelids hurt and the four-legged may not like your manipulations.

Sour crusts should be soaked until they are removed with a light movement of a cotton sponge. Adhesive wool can not be pulled, trimmed (if we are not talking about long hair on the face). For each eye, only clean sponges, cotton wool and gauze cuts should be used. It is advisable not to save consumables and not to wipe the eyelids with one side of the sponge twice. After the procedure, each eyelid needs to be wet with a clean sponge or napkin.

With obvious inflammation of the follicles, a tetracycline ointment should be laid over the eyelids or use a similar drug for treatment. In the first procedure, you may encounter fierce resistance, but relief will come quickly and the dog will understand that you are acting for her good. Do not delay the treatment, and in case of difficulties, consult a doctor, running conjunctivitis of any type can develop into a chronic problem that you will have to deal with constantly.
