 Existpathologies that, in the absence of timely and proper treatment, lead to the death of the animal.

Worst of all, many owners neglect vaccinations, and vaccination is sometimes the only protection against deadly diseases and can save a pet’s life. Puppies and older dogs are more vulnerable to serious diseases than healthy, strong dogs in their prime, so this category should be given special attention.

The plague of carnivores or, as this viral disease is more commonly called, distemper, has been known since the time of domestication of animals. The pathogen, which is carried by sick dogs and even insects, enters the body through food or the respiratory tract. Most often, animals get sick in spring and autumn, when their immune system is most weakened.

The danger is that the distemper is difficult to diagnose. In the first three weeks, the dog does not show signs of infection, but it is a carrier and spreader of the virus. 

The disease proceeds rapidly, and if medical assistance is not provided to the dog within 2-3 days, the probability of death is high. The treatment carried out increases the chances of recovery without complications for the body.


Clinical picture of leptospirosis:

  • lack of appetite;
  • vomiting, diarrhea;
  • general exhaustion;
  • an increase in body temperature up to 41.5 degrees;
  • blood clots in stool and urine.

Lack of treatment leads to the fact that after 2-3 days the dog dies from intoxication of the body. To date, effective methods have been developed for the treatment of leptospirosis, and if the owner notices dangerous signs in time, then the animal can be cured.

infectious hepatitis

A parasitic disease caused by echinococcus. Helminth larvae rapidly spread in the external environment along with the feces of a sick animal. It can also be transmitted to a person, causing him to form parasitic cysts in various organs – the liver, kidneys, lungs, brain, heart.

Echinococcosis is severe, causing intoxication of the body, which, in turn, can provoke abdominal ascites – treatment in dogs here , and in the worst case, death.
