Infectious diseases of dogs: what are they?


No dog is immune to infectious disease. It is therefore up to each owner to ensure the good health of his animal through regular visits to the veterinarian. He must also protect his little companion against bacteria, viruses and other infectious agents responsible for many pathologies, some of which can be very disabling, even fatal. Here are the main infectious diseases in dogs and the possible symptoms.

Canine leptospirosis

This Stuttgart epidemic is a extremely contagious zoonosis which is responsible for the leptospires (Leptospira interrogans). These bacteria contaminate both ponds and puddles or the water that stagnates in saucers. The dog is therefore very exposed to it by quenching his thirst anywhere. It is also known that the urine of wild animals carrying pathogens (particularly rats) promotes soil contamination and therefore disease transmission.

Symptoms of leptospirosis are dark urine, high fever, vomiting, sometimes bloody diarrhea, jaundice (yellowing of the mucous membranes and skin), severe dehydration, lethargy.

The dog must receive antibiotics, analgesics, an antidiarrhoeal and its rehydration is necessary. In the most serious cases, the animal is hospitalized, organ damage (renal damage in particular) which can lead to its death. Fortunately there is a leptospirosis vaccine. It is therefore strongly recommended to ensure that a dog’s vaccination is up to date.

Distemper

More common in fairly young adult dogs and puppies, this infectious disease is highly contagious and can be fatal. However, she is non-transmissible to humans. It is a viral disease of which the culprit is a Paramyxovirus.

Symptoms of distemper> are discharge from the eyes and nose, fever, gastrointestinal disturbances, dehydration, neurological disturbances, breathing difficulties, increase in the stratum corneum (hyperkeratosis) in the stomach. level of the pads or the truffle.

In the current state of knowledge, we do not have no treatment specific against this infectious viral disease. The only possible treatment is antibiotics and if necessary rehydration of the dog by infusion. Prevention of distemper is through vaccination.

The infectious tracheobronchitis

it’s about the kennel cough, an infectious disease more common in dogs that live in communities. It is very contagious, the animals becoming contaminated by their postilions when they sneeze or cough. She may have different virus for responsible such as canine adenovirus or Parainfluenza as well as a bacterium very specific, namely Bordetella bronchiseptica.

The main symptoms of infectious tracheobronchitis are fits of dry cough, sneezing and high temperature for the simple form, to which in the complex form are added great fatigue, vomiting, purulent discharge from the eyes and nose, severe breathing difficulties, and sometimes even the dog may present with bronchopneumonia. The complex shape can be deadly in the absence of support.

Of course, the treatment is decided on a case-by-case basis and depending on the severity of the cough in the kennel. The simple form heals in less than a month. However, it is recommended to vaccinate your dog against this disease.

Borreliosis

It is Lyme disease. These are the ticks infected with the bacteria Borrelia burgdorferi which, by biting the host dog, transmit this infectious disease to it.

The symptoms of borreliosis appear quite late, sometimes several months after infection. It is lameness, joint pain, fever, sometimes vomiting, depression, and in chronic form, kidney problems, heart and / or neurological disorders. Some dogs are what are called healthy carriers. They have no symptoms.

Lyme disease requires a long-term treatment. Prevention involves the regular use of antiparasitics, the systematic inspection of the dog’s hair and skin after a walk but also, especially for hunting dogs and all other dogs that spend a lot of time in nature, by the vaccination.

Parvovirus

This highly contagious infectious disease maybe deadly – especially in older dogs, those who are already in poor health and in puppies – because the white blood cells are attacked, which considerably weakens the animal’s immune system. It is common in dog farms and shelters where animals are contaminated by their droppings. Its responsible is a virus of great resistance: the canine parvovirus.

The symptoms of parvorirosis are among others fever, vomiting, hemorrhagic diarrhea whose odor is particularly unpleasant, great weakness, dehydration.

THE’dog hospitalization having parvovirus is inevitable because the animal must be able to benefit from intensive care and must be placed on an infusion. Antidiarrhehics, antivomitives, antibiotics and rehydration are part of the treatment protocol.

Staphylococcal contamination

This skin infection is usually caused by the bacteria Staphylococcus pseudintermedius. She trains dermatitis and purulent inflammation skin. The symptoms are itching, hair loss locally, redness, boils, abscesses. The prescription of antibiotics is essential because in the absence of treatment, the inflammations are likely to reach the dog’s bones or even his heart.

Colibacillosis

It’s here E-coli bacteria (Escherichia coli) which is responsible for this infectious disease, and the state of health of already fragile dogs is particularly exposed to serious forms.

The main symptoms of colibacillosis are diarrhea, vomiting, urinary tract infections causing severe pain and, in bitches, uterine inflammation. The treatment is of course adapted on a case by case basis. It may rely on pain relievers and antibiotics.

Salmonellosis

It is a bacterium, salmonella, which is at the origin of this infectious disease. The dog can be a victim when it is in contact with barnyard bird droppings or if he eats raw poultry meat as soon as it is contaminated by the pathogen. Salmonellosis has serious consequences in dogs with weakened immune systems.

From symptoms of salmonellosis we find fever, vomiting, bloody diarrhea, loss of appetite, apathy.

The treatment is based on antiemetics, a digestive dressing, rehydration of the animal which also receives a broad spectrum dewormer. In severe cases, the veterinarian also prescribes antibiotics. Note that salmonellosis is an uncommon disease in dogs.
