Canine distemper is one of the best known. Most feared infectious diseases of dogs. canine distemper virus occurs in all countries where dogs are kept. Is still widespread in this country. Your dog can be infected not only by contact with another dog. Danger threatens rather also with the forest walk, because z. B. Martens and ferrets can transmit the disease.

First signs of the disease appear about 1 week after infection. They begin with high fever, loss of appetite and languor. The symptoms are accompanied by initially watery-clear eye and nose discharge, which in the further course then becomes viscous-purulent. This discharge is highly contagious. Either immediately afterwards, or after a period of apparent recovery, other symptoms of illness may occur: Vomiting, watery to bloody diarrhea (intestinal form of distemper) and/or coughing, difficulty breathing, pneumonia (pulmonary form of distemper.). A particularly feared complication is the so-called. nervous form of distemper. The distemper virus causes damage to the brain. This manifests itself in mental changes, tremors, balance disorders, paralysis and seizures, comparable to the appearance of epilepsy. The severity of the different forms can vary. The "nervous" form ends however practically always fatally and/or. requires that the dog must be euthanized for animal welfare reasons.

Hepatitis (H.c.c.)

There is also a contagious viral hepatitis in dogs. However, only dogs are endangered; this infectious disease is not transmissible to humans. Sick, but also healthy appearing dogs are the main carriers of the disease. Direct contact between dogs is not always necessary, because the virus remains contagious for a long time and can be transmitted indirectly. Dogs that have survived the disease can still excrete and spread hepatitis viruses for months.

The disease begins, like all viral infections, with fever, general languor, loss of appetite. In the further course of the disease there is discharge from the eyes and nose (for this reason the disease was often confused with distemper), vomiting, sometimes diarrhea and pain in the liver area. The liver damage causes among other things disturbances in the blood coagulation. In addition, this disease can also cause temporary corneal clouding of the eye and chronic kidney damage. Severely ill dogs die under convulsions sometimes even overnight, without having been ill for a long time before. Dogs that survive show decreased weight gain, and often are left with chronic hepatitis.


At the beginning of the 80s, a deadly viral infection spread fear and terror among dog owners practically overnight: parvovirosis. Parvoviruses, the pathogens of this disease, are excreted by affected dogs millions of times over a long period with the feces. Virus-containing excrement is thus the main cause for an infection. Particularly serious is the problem that the pathogens are very long-lived. Even years later they can cause an illness. Virtually any "dog poop" poses a potential threat. Be it that your dog sniffs it when going out, or that you yourself carry the virus, z. B. adhering to the shoes, bring home with them.

The disease initially begins with fever and dullness. Soon after, vomiting and severe, usually bloody diarrhea occur. In very young puppies, infection can lead to acute cardiac death without the puppies having previously shown signs of illness. Diseased dogs must immediately receive intensive veterinary treatment. Since drugs are ineffective against the virus itself, it is often fatal, especially in younger dogs, despite intensive treatment. In dogs that survive the disease, permanent heart damage with correspondingly reduced performance can remain.

Parvovirosis is sometimes referred to as the "feline plague of dogs". However, infection by cats is excluded. Dogs, on the other hand, can act as a source of infection for cats in rare cases.

New test results from Prof. Truyen (Ludwig-Maximillian University of Munich) have shown that vaccination twice against parvovirosis is not sufficient in many cases to protect dogs safely against parvovirosis. Based on the results of the study, Prof. Truyen therefore to an early parvo vaccination from the 6. week and to a revaccination in the 15. – 16. Week of life. These infectious diseases are caused by certain bacteria. Can affect both animals and humans.

Dogs of all age groups are susceptible to the disease. Infected dogs can excrete pathogens in urine for a long time. In addition, rats are. Mice are an important source of infection. However, the dog does not necessarily have to have direct contact with these animals or with other dogs of the same species. The pathogen can survive for a long time in puddles, so that dogs that drink from them can also be infected in this way.

One to two weeks after infection, the disease occurs with typical symptoms that are often difficult to interpret. In severe cases, the disease begins with sudden weakness, refusal to eat, vomiting and fever. Respiratory problems and increased thirst are other signs, as well as frequent urination. In some dogs jaundice develops. Diseased dogs are reluctant to rise and express pain when prere is applied to the kidney area. Surviving the disease can leave chronic kidney damage.

Coronavirus infection

This is a highly contagious intestinal infection known only recently. The disease can affect dogs of any age. The infection is known in Europe, North America and Australia, but is likely to be widespread worldwide. The virus causes, especially in young dogs, a reluctance to eat, watery diarrhea with blood and vomiting. The disease is therefore difficult to distinguish from parvovirosis, which is usually much more severe.

Infection with coronavirus occurs through contact with feces excreted by infected dogs.

An effective vaccine is not yet available in Germany. However, your veterinarian will be happy to inform you about the current state of development.

Viral cough

This disease of the trachea and bronchi is often misleadingly called kennel cough. The reason for this is that although it most often affects dogs that live closely with many others (z. B. in the kennel). In principle, however, every dog can be affected by it, which comes in contact with conspecifics during the run.

The cause of the cough are certain types of viruses, such as z. B. the Parainfluenza-. The adenovirus. Parainfluenza-. The adenovirus. Bacteria can contribute to a complicated course of the disease with pneumonia, although in the rarest cases there is acute danger to life. Agonized, dry cough, which occurs in fits and starts, but has an extremely negative effect on the general condition and performance of the dogs. Wherever many dogs come together, the cough spreads very quickly.

Special modern combination vaccines, commonly used to protect against the diseases described in this brochure, also protect against parainfluenza and adonaviruses, which are involved in causing viral coughing.


You are certainly familiar with the veterinary police signs indicating a "rabies exclusion zone" at many town entrances. The legislator thus takes into account the fact that rabies is still one of the most dangerous viral infections for humans and animals. Susceptible to the disease are all warm-blooded animals. The main source of infection is wild carnivores, primarily foxes. Recently, however, the virus has also been detected in bats on several occasions. Rabies viruses are excreted by infected animals with their saliva. Bites from animals infected with rabies are particularly dangerous because the virus enters the body through wounds. Therefore, you should also avoid "particularly trusting wild animals" or, for example, a run over fox with the bare hand to touch.

In typical cases, rabies progresses in three phases. The first sign is often a change in behavior (shy animals become z. B. trusting). In the further course it can come to states of excitation (excitation stage) and finally shortly before death to paralysis (paralysis stage). Since the symptoms of rabies can be very diverse, it is strongly recommended that if you or your dog has had contact with a rabid or suspected animal, you immediately consult a doctor or veterinarian. Vaccinated dogs are in this case legally better off than unvaccinated dogs, for which an immediate killing can be ordered.

For travel abroad, it should be noted that the individual countries have ied so-called entry regulations. In the majority of cases, entry with a dog is only permitted if a valid rabies vaccination can be proven. This usually must be at least four weeks, but not more than a year ago. Further information can be obtained from veterinarians, the German Green Cross, veterinary offices and automobile clubs.


The safest way to prevent life-threatening infectious diseases is vaccination. Vaccines are rightly considered to be the most effective drugs of all!

Until today there are unfortunately no medicines, with which a virus infection can be healed. In the event of illness, the veterinarian can only endeavor to mitigate the course of the disease and prevent the worst. Therefore, in the case of viral diseases, vaccination is the safest way to prevent disease.

Vaccination makes the dog immune. This immune protection only covers the disease that was vaccinated against. Therefore, distemper vaccination does not protect against parvovirosis and vice versa. So that the dog does not have to be vaccinated against each individual disease, modern vaccine research has developed so-called combination vaccines, which have many advantages especially for the annual repeat vaccination and are therefore preferred today.
