Canine microcephaly, or canine microviral disease, is a virulent infectious intestinal disease caused by microviruses. It is characterized by severe vomiting, hemorrhagic enteritis and a significant decrease in white blood cells and myocarditis. The onset of canine microviral disease is related to the breed: purebred dogs mongrel dogs native breeds, mainly related to the high susceptibility of purebred. Second, the highest incidence of dogs under 1 year old, of which, 1 month old dogs due to lactation, the influence of maternal antibodies, the rate of infection and morbidity is very low: after 2 months of age, due to the disappearance of maternal antibodies, and their own immunity is not yet sound, when the dog is very susceptible to infection and morbidity; 2 years of age or older dogs have a lower rate of infection, but not the same as not infected. The disease can occur throughout the year, with the highest incidence in winter and spring and a lower incidence in summer. Causes of what causes dogs to get small? The main reasons are as follows: 1. improper diet: this is the main cause of common microscopic disease, including feeding dogs oily food, cold food, leftovers, chicken and duck and other poultry bones. 2. cold: cold can lead to dog diarrhea. 3. infected: the speed of transmission of microscopic is very frightening, if the healthy dog and sick dog did not do a good job of isolation, air and feces, saliva and other sources of infection. . 4. Internal parasites cause diarrhea in dogs: This is a fatal cause for small dogs. Dogs got small, the main performance of the following three types: 1. enteritis type: this type is the most common, the beginning of the disease depression, loss of appetite or wasting, lying down. Body temperature rises above 40 ℃, there is a sense of thirst, but individual dogs do not appear to increase body temperature. Vomiting, first vomiting food, then yellow watery mucus; diarrhea, first yellow watery stool, then tomato juice-like red blood-like thin stool, and fishy smell. In the late stage of the disease, there is severe dehydration, dryness at the end of the nose, sunken eyes, pale mucous membranes, rapid wasting, and the whole body emits odor. The duration of the disease varies from 3-5 days in puppies to 7-14 days in adult dogs over 12 months of age, with a lower mortality rate. 2. Myocarditis type: This type is less common, mostly seen in puppies 2-3 months of age, showing mental depression, fast and weak heartbeat, and the sick dog often dies of sudden heart failure, with a shorter duration of the disease. 3. Mixed type: This type has both the typical symptoms of the above two types, mostly First appear enteritis type, followed by the symptoms of myocarditis, the rate of death is higher. Treatment If your dog is infected with microcephaly, you must go to the hospital, the sooner the better, the doctor will carry out the following treatment: 1. Immune serum: early use can improve the efficacy. If there are multiple pet dogs at home, once a dog is diagnosed with the disease, the other dogs should be given high immunity serum or recovery dog serum immediately. The dosage of high immune serum is 0.5-1 ml/kg body weight, and 0.5-2 ml/kg body weight of rehabilitated dog serum for 3-5 days. Highly immune serum can be used together with other antibacterial and anti-inflammatory drugs to improve the immune effect. 2. Rehydration: Sick dogs often die due to dehydration, so rehydration is the main measure to treat this disease. According to the degree of dehydration and the general condition of the dog, the required components and the amount of rehydration fluid should be determined. 3. Antibacterial and anti-inflammatory: various types of broad-spectrum antibiotics can be applied, but do not use them for a long time to prevent the normal intestinal flora from becoming dysbiosis, which will delay the recovery of intestinal digestive function. 4. Anti-emetic: those who vomit severely can be injected intramuscularly with Emol, extirpate (gastric complex) 0.3-2 ml. 5. Anti-shock: those with obvious shock symptoms 6. strengthen care: pay attention to the sick dog to keep warm, diarrhea during the period should stop feeding milk, eggs, meat and other high-protein, high-fat feed, give easily digestible feed, to alkaline light gastrointestinal burden, improve the cure rate. Prevention How to prevent the occurrence of canine microcephaly? You can do this through the following 5 points. 1. good vaccination: at 45 days of age for the first immunization, interval of 21 days for 3 consecutive immunizations, after 11 months every immunization 1. 2. once the occurrence of micro-virus disease, the dog should be quickly isolated, with Dupont can be a comprehensive and thorough disinfection. Disinfect the environment and utensils after isolation, drying and ultraviolet disinfection. Sick and dead dogs should be burned or buried. 3. long-distance transport of dogs, should first be injected with serum: newly purchased dogs, especially newly weaned puppies, should be fed at home, observed for about 1 week, and then immunized. 4. strengthen the care of dogs, especially in winter must pay attention to insulation. 5. vaccination is an effective measure to prevent canine microvirus disease, can be vaccinated with Intervet IV, Wei Jia Wu, Wei Jia H. prevention. Note that 1. in order to block infection with micro-virus, the home should be thoroughly disinfected. 2. if there are other dogs at home should be promptly isolated, observed after treatment (emergency immunization, such as injection of serum, monoclonal antibodies, etc.). 3. if there was a sick dog died at home, there is a new dog arrived, it is recommended that in the case of thorough disinfection, still do all the immunization for the new dog to reduce the risk of being infected.
