How to treat canine parvovirus? Medical health… Parvovirus
1. Canine parvovirus disease is an acute infectious disease caused by canine parvovirus infecting puppies. There are two clinical phenotypes. The hemorrhagic enteritis type is characterized by severe vomiting, hemorrhagic enteritis and a significant decrease in leukocytes; the myocarditis type is characterized by sudden death. Regardless of the type of clinical manifestation, it is characterized by high morbidity, high mortality and strong infectivity.
Parvovirus (Parvovirus), the virus particles have no envelope, CPV has strong resistance to the outside world, is resistant to alcohol, ether, chloroform, and has a certain tolerance to temperature. 65 ℃, 30 seconds without losing its infectivity, and long-term storage at low temperature has no significant effect on its infectivity. It survives for 6 months at 4 ℃ ~ 10 ℃, 2 weeks at 37 ℃, 24 hours at 56 ℃, 15 seconds at 80 ℃, and only slightly decreases in infectivity when stored at room temperature for 3 months. It can survive in feces for several months to several years. The most effective disinfectants for CPV are formalin, β-propiolactone, sodium hypochlorite, oxidants, etc. In addition, ultraviolet rays can also inactivate it.
2. Transmission:
Sick dogs are the main source of infection for this disease, and the feces, urine, vomitus and saliva of sick dogs contain the highest amount of toxins. Sick dogs continue to excrete toxins and infect other healthy dogs. Recovered dogs carry toxins in their feces for a long time. Therefore, once the disease occurs in a dog group, it is extremely difficult to completely eliminate it. In addition to dogs, wolves, foxes, and raccoons can also be naturally infected. This disease is mainly transmitted through direct or indirect contact.
3. Manifestations:
Dogs infected with canine parvovirus can be clinically divided into enteritis type and myocarditis type.
Enteritis type: The incubation period of natural infection is 7 to 14 days. The initial symptoms are fever, body temperature can reach above 40°C, depression, no eating, and vomiting. The initial vomitus is undigested food and white foam (gastric acid), followed by mucus and yellow-green liquid. Diarrhea begins one day after the onset of the disease. At the beginning of the disease, the feces are thin and paste-like or half-formed, with a certain fishy smell. As the disease progresses, the feces become dark green or yellow jelly-like. Later, the feces are ketchup-colored or coffee-colored, smelly, the number of defecation is irregular, and there are symptoms of tenesmus. After bloody stools, sick dogs show sunken eyeballs, dry nasal cavity, general weakness, and significant weight loss. At the same time, they are accompanied by pale conjunctiva and oral mucosa, and severe anemia symptoms. If the disease is not treated in time, it can cause toxin absorption and poisoning of intestinal contents until shock and death. Occasionally, dogs have the following conditions: the feces are transparent watery, with blood in them, with a fishy smell, or the feces are white and thin.
Myocarditis type: more common in puppies around 40 days old, sick dogs have no obvious clinical symptoms, some suddenly have difficulty breathing, heart failure, and die in a short time; some sick dogs die after mild diarrhea. Canine parvovirus myocarditis type is caused by canine parvovirus attacking the dog’s myocardial cells, which can destroy the dog’s myocardial cells in a short time. Then the dog will have asthma, cyanosis of oral mucosa and skin, and sometimes sudden death from exhaustion is the only physical symptom of the disease in puppies. Puppies that have tolerated the disease may still die from the disease weeks or even months after infection due to permanent myocardial damage. It is more common in puppies, and there is a 10% chance that canine parvovirus will attack the dog’s intestinal epithelial cells and myocardial cells at the same time.
4. Prevention:
First, vaccination should be done regularly. Clinically, it is found that the immune protection of domestic canine hexavalent vaccine is low. It is recommended to inject imported canine bivalent vaccine. Puppies can be injected when they are more than 45 days old and in a healthy state. Depending on the brand, one or two injections are required. The bivalent vaccine is a canine parvovirus and canine distemper vaccine.
Second, isolate from sick dogs and thoroughly disinfect dog supplies .
Third, use appropriate medications and do not abuse antibiotics and other drugs.
5. Treatment:
During the onset of canine parvovirus, there will be severe diarrhea, and the excrement will change from yellow-green to coffee-colored, or bloody stools like tomato sauce with a special fishy smell. During the dog’s illness, the owner needs to take good care of it, have confidence in it, and encourage it more… Dogs understand human nature, as long as they have a breath, they will persist!
1. During the treatment, absolutely no water or food should be fasted (the hospital will give the dog infusion to replenish water and physical strength, don’t worry)!
2. You need to go to the pet hospital for infusion treatment every day. Keep the dog warm!
3. During this period, the dog is basically listless and sleepy. It is a normal phenomenon during treatment.
4. The first three days are the most important and dangerous period. If you get through it, there is basically no danger to life… Continue to cooperate with the treatment.
5. Pay attention to the hygiene and disinfection of the dog’s kennel and the area where the dog often moves. The hospital should have special disinfectants for viruses.
The incubation period of the disease is 3-5 days, and it often occurs just after a change of environment (such as bathing a newly bought puppy). Overeating is a trigger. Most of the diseases present as enteritis syndrome, and a few present as myocarditis syndrome.
Dogs with enteritis are initially depressed, anorexic, occasionally have fever, soft stools or mild vomiting, and then develop frequent vomiting and severe diarrhea. At first, the feces are gray, yellow or milky white, with jelly-like mucus, followed by foul-smelling soy sauce-like or tomato juice-like bloody stools. Sick dogs quickly become dehydrated, lose weight, have sunken eye sockets, messy fur,
inelastic skin, cold ears, nose, and limbs, are highly depressed, go into shock, and die.
It usually takes no more than 2 days for the initial symptoms to become severe, and the entire course of the disease usually does not exceed a week.
