Clinical symptoms of canine infectious hepatitis

The English name of canine infectious hepatitis virus is Canine infectious hepatitis. Canine infectious hepatitis is caused by canine adenovirus type I It is an acute septicemic infectious disease in canines, which mainly passes through the digestive tract infection and may also pass through the placenta.

1. Hepatitis type

The most acute type is in newborn dogs and dogs under 1 year old. Body temperature rose to 41 degrees Celsius, abdominal pain, vomiting, diarrhea, and bloody stools. Most of them die within 24 hours. In patients with a slightly longer course of the disease, in addition to the above symptoms, depression, runny nose, conjunctivitis, inflammation, shame and tearing can also be seen. Bleeding or spotting in the mouth and gums. Its specific symptoms are subcutaneous edema of the head, neck, eyelids, and abdomen. The mucous membrane can be seen to be slightly yellow. In mild cases, symptoms of anorexia, slightly higher body temperature, and runny nose usually last 2-3 days.

2. Respiratory type

Sick dogs have elevated body temperature, accelerated breathing, fast heartbeat, and irregular rhythm. cough. There is serous or purulent nasal fluid. Some sick dogs vomit or pass loose stools. Some sick dogs have swollen tonsils accompanied by pharyngitis.

In the hepatitis type of dead dogs, a large amount of serous or blood-like fluid can be seen in the abdominal cavity. The liver is enlarged and has bleeding spots or spots. Bleeding may be seen in the gastrointestinal tract. Lymph nodes all over the body are swollen and bleeding. In respiratory cases, changes such as lung enlargement and congestion, bronchial lymph node bleeding, tonsil enlargement and bleeding can be seen.

Based on the above characteristics, it is not difficult to diagnose. Since the virus has the ability to agglutinate type 0 human red blood cells, chicken red blood cells and guinea pig red blood cells, red blood cell agglutination and red blood cell agglutination inhibition tests can be performed if conditions permit. Diagnosis should be differentiated from canine distemper and leptospirosis.

Key points of prevention and treatment of canine infectious hepatitis

The main symptoms of canine infectious hepatitis include blue discoloration of the cornea of ​​sick dogs, jaundice, anemia, etc. Laboratory examination can observe changes in the dog's blood image, decrease in red blood cell count, hemoglobin, specific volume, and decrease in white blood cells. Because the treatment of canine infectious hepatitis is complicated, owners are advised to seek medical treatment promptly to avoid delaying the dog’s condition.

Feeding and management should be strengthened and comprehensive veterinary health and prevention measures should be strictly enforced. Get regular immunizations. Commonly used vaccines include canine infectious hepatitis attenuated vaccine. Each dog is injected with 1.5ml subcutaneously after weaning, and another 2ml is injected at intervals of 3 to 4 weeks. From now on, it will be injected once every six months, 2ml each time. The immunity period is half a year. This vaccine should not be used during an epidemic. There are also two vaccines for canine infectious hepatitis and canine parvovirus enteritis and five vaccines for dogs. When a dog becomes ill, in order to alleviate the condition and control the infection, canine infectious hepatitis hyperimmune serum can be used. Each dog can be injected subcutaneously or intramuscularly at 2m1 per kilogram of body weight for 3 days.
Broad-spectrum antibiotics can be used to prevent secondary infections. Appropriate measures can be taken according to the symptoms of sick dogsAllopathic and systemic therapies are also necessary. For example, Gantailo tablets can be taken orally to protect the liver and promote gallbladder. In order to improve the general condition and enhance the body's resistance, infusions and multivitamin preparations can be given. Dogs that are unlikely to be cured should be immediately culled, eliminated, and disposed of harmlessly. The polluted environment can be disinfected with 3% formalin, caustic soda water, sodium hypochlorite or 0.3% peracetic acid.

Precautions for the treatment of canine infectious hepatitis

Canine infectious hepatitis is an acute septicemia infection in dogs. It mainly destroys intranuclear inclusion bodies in the center of liver lobules, liver parenchymal cells and cortical cells, and prolongs the coagulation time. Canine infectious hepatitis is mainly infected through the digestive tract, and puppies between 2 months and 1 year old are more susceptible to infection. Therefore, during the treatment process, what issues should dogs infected with the disease pay attention to so that they can recover faster?

1. Canine infectious hepatitis is caused by canine infectious hepatitis virus through the digestive tract. It has the characteristics of wide prevalence, rapid spread, and high incidence. Therefore, when sick dogs are found, they should be isolated in time to prevent the spread of the epidemic source.

2. Strengthen the feeding and management of sick dogs, and carry out sanitation and disinfection of the surrounding environment.

3. Develop an immunization program, prepare vaccinations, and improve the body's immunity. At present, the two-combination vaccine for canine distemper (detailed introduction) and the five-combination vaccine for canine distemper are widely used. The first vaccination is given at 2 to 3 months of age, and again after 20 days.

4. Early detection, early diagnosis and early treatment of sick dogs can reduce death or corneal damage and improve the cure rate. The dog should be given mental comfort and encouraged to take medicine to improve its confidence in restoring light after corneal damage.
