What is canine distemper

Canine distemper is a highly contagious infectious disease caused by the canine distemper virus. It is extremely contagious and has a mortality rate of up to 80%. %above. In the early stages of canine distemper symptoms, the dog's body temperature is as high as 39.5 to 41 degrees Celsius, with loss of appetite, depression, watery secretions from the eyes and nose, sneezing, and diarrhea. Within the next 2 to 14 days, if the temperature rises, coughs, purulent nasal discharge, and purulent eye excrement appear again, it is already the middle stage of canine plague. At the same time, secondary gastrointestinal diseases include vomiting, diarrhea, and loss of appetite. Highly depressed and lethargic. Typical neurological symptoms of canine distemper will appear in the later stages of the disease, such as foaming at the mouth and convulsions. At this time, it is generally very difficult to cure, but some cases have been successfully cured.

Canine distemper is a very serious infectious disease, generally characterized by complex fever, acute nasal catarrh, bronchitis, catarrhal pneumonia, severe gastroenteritis and neurological symptoms. A few sick dogs will also develop nasal, Hyperkeratosis of the foot pads. It is often mixed with parvovirus, canine infectious hepatitis, pneumonia, etc., so the mortality rate is extremely high. The early stage of the disease is similar to fever and is easily ignored by parents. It manifests as conjunctivitis and dry cough, which then turns into wet cough, dyspnea, vomiting, diarrhea, intussusception, and ultimately death due to severe dehydration and weakness in the child.

The epidemic of canine distemper

Canine distemper occurs in almost all countries in the world and occurs in all dog breeding countries. However, the cold season between October and April is the most frequent period of time, especially in densely populated areas, residences and kennels in various countries. Once the disease occurs in a dog, it is difficult to prevent infection in other dogs unless completely isolated. Dogs who recover can have lifelong immunity.

Canine distemper symptoms

The incubation period of canine distemper is 3-9 days. Symptoms vary and are related to the intensity of virulence, environmental conditions, age and immune status. The first symptom of canine distemper is an increase in body temperature, which lasts for 1-3 days. Then it subsides, much like the characteristics of recovery from a cold. But the temperature rises again after a few days, and the duration is uncertain. Tearing, redness of the conjunctiva, and eye secretions from liquid to mucopurulent may be seen. The nose is dry and nasal fluid flows out. It is serous nasal fluid at first and then turns into purulent nasal fluid. At the beginning of the disease, there was a dry cough, which later turned into a wet cough and difficulty breathing. Vomiting, diarrhea, intussusception, and ultimately death from severe dehydration and weakness.

Nervous symptomatic canine distemper mostly appears about 10 days after the above symptoms. Clinically, neurological symptoms frequently occur in cases of footpad keratosis and nasal keratosis. Because canine distemper virus attacks different parts of the central nervous system, symptoms vary. The virus damages the brain and manifests as epilepsy, circling, abnormal standing posture, unsteady gait, ataxia, paroxysmal twitching of masticatory muscles and limbs and other neurological symptoms. The prognosis of this type of neurological canine distemper is usually poor. .

Sequelae of canine distemper

Canine distemper virus can cause eye damage in some dogs.The clinical manifestations are conjunctivitis and keratitis. Keratitis is more common around 15 days after onset. Corneal whitening can occur in severe cases such as corneal ulcers, perforations, and blindness. The disease has a high mortality rate in puppies, reaching 80-90%. Symptoms such as pneumonia, enteritis, and intussusception may be secondary.

Clinically, once the characteristic canine distemper symptoms appear, the prognosis is very poor. Especially unvaccinated dogs. Although symptomatic treatment is provided clinically, the development of the disease is very difficult to control, and most patients die from neurological symptoms and failure. Dogs that partially recover generally have varying degrees of sequelae.

Clinical characteristics and treatment of canine distemper

Biphasic fever leukopenia, conjunctivitis, bronchitis, catarrhal pneumonia, gastroenteritis, dermatitis and neurological symptoms, part The foot pads of the patient were highly keratinized, and obvious neurological symptoms appeared in the later stage.

Note: Canine distemper rarely occurs alone clinically. Most cases have mixed infections. Secondary bacterial infections are one of the main causes of increased mortality. If pneumonia is complicated, the mortality rate can be as high as 90%.

Puppies under 2 months old rarely get sick due to the presence of maternal antibodies, while puppies between 2 months and 6 months old have a higher incidence. As they grow older, the incidence gradually decreases. The above-mentioned dogs are rarely infected with this disease. Except for a few of the most acute, the course of the disease can last from 1 to 2 months for most sick dogs, and recovered dogs can obtain immunity for life. Sick dogs are the main source of infection of this disease, and their virus-carrying period is not less than 5 months. .

In the early stage of the disease, the canine distemper monoclonal serum is injected subcutaneously or intramuscularly, and combined with Xi'an Hongbei's Gankang Injection to clear away heat and relieve symptoms; Yanjuke Injection and Chongke Stop Injection are used to prevent infection and immune whitening. In order to improve immunity, the above formula is indispensable for protein injection. It is Xi'an Hongbei's classic treatment formula for treating dog plague.
