The most common infectious diseases in dogs

A dog can undergo a fairly large number of infectious diseases. The most common and dangerous are adenovirus infection, carnivorous plague, hepatitis, parvovirus enteritis, leptospirosis and rabies.

Adenovirus infection or nursery cough

This disease affects the respiratory tract and gastrointestinal tract of dogs of all ages. The dog's throat mucus reddens, a runny nose, convulsive cough, wheezing in the lungs appears. Often there is vomiting, diarrhea (possibly with blood). The dog does not eat, is oppressed. In fecal masses, residues of undigested food are noticeable. Additionally, fever and signs of pneumonia may occur.

A dog is infected by airborne droplets and all dogs rapidly fall ill in kennels. Often, the infection is on overexposure, after visiting competitions and exhibitions. If the dog is strong enough, recovery occurs spontaneously in 7-14 days. The best prevention is complex vaccine vaccine.

Plague carnivorous

Symptoms of this dangerous infectious disease are diarrhea, runny nose, cough, conjunctivitis, suppression of the immune system. In pregnant bitches, abortions occur.

There are specific forms of infection: photophobia, keratitis with the formation of ulcers, even blindness may develop. On the skin of the lower abdomen, blisters and reddened pustules appear on the inside of the ears and thighs. Nervous phenomena are common: anorexia, epileptic seizures, paralysis, tic, mental disorders.

  • A dog can become infected through the discharge of sick dogs or sick dogs, as well as through dishes, food, clothing. Only young animals up to the age of two are ill.
  • The respiratory and intestinal form of the distemper in dogs can be cured, but in severe febrile, pneumonic and nervous forms the prognosis is poor.
  • In order to prevent the need to vaccinate puppies at the age of 8 weeks with repeated combination vaccine in 3-4 weeks.

Infectious hepatitis

Inflammation of the liver caused by canine adenovirus. In most animals, the disease is latent and rarely clinically manifested. Most often at the same time with the plague of dogs.

In the acute course of the disease puppies die. In adult dogs, it is much less common. Prevention of hepatitis in dogs is vaccination.

Parvovirus enteritis

Infection occurs through the hair of convalescent animals, food contaminated with feces, through clothing and items of care.

  • The main symptoms are persistent vomiting, even in recovering animals, diarrhea, fever or, conversely, fever, weakness, anorexia, abdominal pain, severe dehydration.
  • Enteritis in dogs is a very dangerous disease and most animals die in the first 4 days of the disease. After this time, the chance of recovery increases. The disease can give a complication to the heart and puppies die from pulmonary edema, a non-purulent myocardial necrosis.

Timely vaccination is needed at 12-14, and then at 16-18 weeks of life and repeat every year.


  • It is transmitted when bitten by sick animals and is always fatal.
  • The incubation period is from 14 days to a year, or even six years.

Symptoms are impaired motor coordination and paralysis. In a classic course, the behavior of the dog changes first; it becomes capricious, fearful, or too friendly. The second stage is different excitement: there is aggression with wandering movements. The dog is restless, losing weight, nibbling foreign objects, it has saliva, coordination of movement is disturbed, and epileptic seizures are possible. By the third stage, paralysis increases.

Common and atypical forms of flow. Quiet rabies in dogs is paralysis without a prior stage of arousal. The dog can not eat anywhere sits down indifferently, her lower jaw hangs down, the third eyelid drops out, her eyes mow.

Prevention of this infectious disease is an annual vaccination.


Like rabies, leptospirosis in dogs is dangerous for humans. Infection of the dog occurs upon contact with the urine of sick dogs.

Symptoms include diarrhea and persistent vomiting, acute renal failure, tonsillitis, gastroenteritis, stomatitis, jaundice, dehydration, nervous system disorders, shortness of breath, photophobia and visual impairment.
