Why does a dog’s eyes fester? The main causes of suppuration

Pus is a fluid secreted from blood vessels in the presence of an inflammatory process. Unlike transparent tears, purulent discharge is cloudy and colored in gray, yellow or green. If the dog’s eyes are festering, then its body can be infected with pathogenic organisms that destroy the immune system.

In this case, the body directs all forces to fight the inflammatory process, remaining unprotected against other threats. This feature increases the risk of complicating the situation and requires immediate action by the owner.

Consider the main causes of suppuration, and treatment methods to restore the health of the eyes of a four-friend.

Causes of infection (route of infection)
The appearance of pus is a reaction of the body to the inflammatory process that arose in the body. The main reasons for the appearance of festering eyes include:

Infections of bacteriological and fungal nature. The greatest danger is staph bacteria, provoking profuse purulent discharge.
Irritation. Hypersensitivity of the mucous membrane of the dog’s eye reacts sharply to household chemicals used when mopping or sprayed during cleaning. Also, the danger comes from tobacco smoke and other pungent substances.
Chronic diseases Congenital or acquired diseases affecting the eyeballs (eyelid ectropion, obstruction of the lacrimal canal) begin to worsen with age due to declining immunity.
Allergic reactions. The classic symptomatology of any allergy is increased tearing. Abundant moisture forms pathogenic microflora. Subsequent growth of bacteria leads to suppuration.
Injuries accompanied by mechanical damage to the eyes. In most cases, only one eye becomes inflamed in a dog. However, with more serious bruises affecting the head, discharge is noted from both eyes simultaneously.
Parasites (helminthiases, ticks and fleas). With bites, a protein substance that causes an allergic reaction enters the canine’s body, and constant itching provokes scratching, which leads to eye injury due to claws.
Viral diseases. In addition to purulent conjunctivitis, infection with the virus is accompanied by other serious symptoms that can lead the animal to death. Among the most common are worth noting:
ehrlichiosis, transmitted by ixodid ticks and dangerous to humans;
Ausesqui disease, called “pseudorabies” and not leaving the pet a chance of recovery;
coronavirus, accompanied by acute diarrhea, killing the body of small puppies due to dehydration;
parainfluenza, leaving the causative agent of the disease inside the recovering dog for six months;
carnivore plague that occurs after eating an infected animal, food or water;
infectious hepatitis caused by adenovirus and dangerous to others within 9 months after the recovery of the animal.
Symptoms
Any inflammation of the eyes in dogs is a symptom that requires an immediate response from the owner. Many causes that affect the state of the visual organ differ in their symptoms. Among the common signs indicating health problems are:

general or local fever;
pain cramps;
decreased activity and appetite;
gait change;
itching
gastrointestinal upset;
rhinitis and bronchitis.
The greatest danger to the pet is a viral and bacterial disease that has a crushing blow to the body:

Staphylococcus When infected with bacteria, the following occurs:
increase in local temperature;
redness;
itching and pain reaction;
pus leading to general intoxication.
Staphylococcus
Staphylococcus
Ehrlichiosis. The destruction of white blood cells and platelets leads to problems with blood coagulation and an increase in internal organs. Depending on the degree of damage to the body, the dog has:
anemia;
seizures and bleeding;
loss of appetite and weight loss;
swelling of the extremities and inflammation of the eyes;
joint pain
fever;
trouble breathing.
Ausesqui’s disease. A sick pet differs from a rabid dog in the absence of a fear of water and a desire to try inedible objects. It appears:
runny nose and cough;
conjunctivitis;
phantom itching, leading to damage to living tissue when scratching teeth;
frequent mood swings from passive to excited;
lack of response to external stimuli.
Coronavirus. Puppies under the age of 3 months are at risk and survive in only 10% of cases. When the disease is recorded:
frequent and watery stools;
conjunctival inflammation;
vomiting
thick or liquid purulent discharge.
Parainfluenza affecting the upper respiratory tract is accompanied by:
Conjunctivitis and rhinitis;
swelling of the oral cavity;
cough, degenerating into bronchitis or pneumonia.
Plague of carnivores. First of all, the virus infects the lymph nodes, causing their inflammation.
