The dog's diarrhea is smelly and bloody or due to canine distemper

Canine distemper usually occurs in unvaccinated puppies, especially those just purchased from dog dealers.

Canine distemper is a highly contagious and fatal infectious disease in dogs caused by canine distemper virus. The fatality rate after infection in puppies reaches more than 80%.

Symptoms of canine distemper

1. Overall manifestations. The affected dog has a loss of appetite or simply refuses to eat, is lethargic, and changes in body temperature are biphasic, that is, the body temperature first rises to 39-41 degrees, lasting for 1 to 3 days, and then gradually subsides, approaching normal temperature, and occurs again a few days later. The body temperature rises and can lead to death in severe cases.

2. Respiratory system type (pneumonia type). It manifests as rhinitis and conjunctivitis, with serous or mucopurulent discharge from the eyes and nose. If it causes ocular neuritis, it can lead to blindness. Viruses invade the lungs and cause interstitial pneumonia, and secondary bacterial infection can cause bronchopneumonia. Clinical manifestations include cough, dyspnea, and crepitus on auscultation.

3. Gastrointestinal type. Manifested by vomiting and diarrhea. The sick dog had severe diarrhea, occasionally passed bloody stools, and developed tenesmus.

4. Neurotype. Canine distemper virus can invade any part of the central nervous system. Clinically, neurological symptoms may appear simultaneously with other systemic symptoms or may appear subsequently. The main manifestations are general twitching, masticatory muscle spasm, turning in circles, and abnormal behavior. When the midbrain, cerebellum and vestibule are damaged, ataxia and abnormal posture are manifested. Spinal infection manifests as abnormal posture, abnormal spinal reflexes, paralysis, etc.

Canine distemper prevention

In the early stage of the disease, large doses of canine distemper hyperimmune serum, canine distemper monoclonal antibodies and canine gamma globulin are used. Canine distemper hyperimmune serum for small dogs 5-10 ml each time, large dogs 20-40 ml each time, intramuscular injection or intravenous infusion, once a day for 3-5 consecutive days; canine distemper monoclonal antibody 5-20 ml, subcutaneous injection, once a day, for 3 consecutive days; canine gamma globulin is 2 ml each time for small dogs, and 4-6 ml each time for large dogs, twice a day, for 3-5 consecutive days.

Notes

Regular vaccination is the most important preventive measure against canine distemper. Canine distemper vaccine can be used to immunize three times at 50 days, 80 days, and 110 days of age, and then boost vaccination once a year. Canine triple vaccine, five-combination vaccine, six-combination vaccine and seven-combination vaccine can also be used, all of which should be used according to the instructions.

Dogs have diarrhea that is smelly and bloody or may be caused by parvovirus

Canine parvovirus is a severe infectious disease caused by canine parvovirus. Puppies aged 4 to 12 weeks are most susceptible to the infection. The incidence rate is higher in winter. Highest. Adult dogs can also become infected, but symptoms are mild.
Sick dogs are mostly characterized by hemorrhagic enteritis or non-suppurative myocarditis. Sometimes the infection rate can be as high as 100%, and the fatality rate is 10%-50%.

The cause of canine parvovirus

1. The impact of canine parvovirus onIt has strong resistance to external factors and can survive for 1 hour in an environment of 60°C. The virus is still infectious in an environment that is acidic or alkaline. The virus can survive for months to years on feces and solid pollutants. It can survive at low temperatures. In the environment, its infectivity can be maintained for a long time. 0.5% formalin, 0.5% peracetic acid, 5% to 6% sodium hypochlorite, etc. can be used as disinfectants for this virus.

2. Sick dogs are the main source of infection of this disease. The feces, urine, vomitus and saliva of sick dogs contain the highest level of poison. Sick dogs continue to excrete viruses and infect other healthy dogs. The feces of recovered dogs carry poison for a long time. Therefore, once the disease occurs in a group of dogs, it is extremely difficult to completely eliminate it.

Key points for diagnosis of canine parvovirus

The prevalence of this disease has no obvious seasonality, but it is more common in cold winter. Puppies that have just been weaned mostly suffer from myocarditis syndrome, while young dogs mostly suffer from enteritis syndrome. At the same time, the disease mainly appears in two clinical forms, namely enteritis type and myocarditis type.

A) Enteritis type:
1. The incubation period is 7 to 14 days.

2. Generally, there is vomiting first and then diarrhea. The stool is yellow or gray-yellow and contains a large amount of mucus and pseudomembrane.

3. 2 to 3 days after the illness, the feces will be like tomato juice, mixed with blood, and have a special fishy smell.

4. The sick dog will soon show symptoms of dehydration. At this time, the sick dog will be depressed, lose its appetite, its body temperature will rise above 40 degrees Celsius, and its thirst will increase.

5. In the later stages, the body temperature of some sick dogs is lower than normal temperature, the mucous membranes are pale, the tail and rear abdomen are often contaminated with feces, and in severe cases, the anus is loose and dilated.

B), myocarditis type:

Puppies have difficulty breathing, hyperpalpitations, pale mucous membranes, physical failure, and often die suddenly.

Preventive measures for canine parvovirus

1. The prevention of this disease is vaccination, usually with canine distemper and other infectious diseases, using a six-linked vaccine or a seven-linked vaccine to co-immunize;

2. The disease progresses quickly, and the younger the dog, the higher the mortality rate. Early treatment is very important;

3. Dogs with myocarditis disease have a rapid course of disease, worsen rapidly, and often die before treatment is available;

4. If dogs with enteritis type can be treated promptly and reasonably, the mortality rate can be significantly reduced. Generally, canine parvovirus hyperimmune serum is used for treatment, and glucose saline is used for rehydration according to the condition. Ribavirin is used to fight viruses, dexamethasone or kanamycin is used to fight secondary infections, and vitamin K is injected intramuscularly.

The bloody diarrhea in dogs may be caused by parasites

The causes of bloody diarrhea in dogs

Generally caused by roundworms, hookworms, tapeworms, and also caused by balls Caused by insects. Due to the thin intestinal cavity of puppies, parasites such as roundworms are relatively abundant. Large in size, it can cause diarrhea in puppies. Losing weight, even vomiting worms in severe cases. Eggs can be found in the feces. Some puppies may develop small intestinal intussusception or anal prolapse.

Solution

Albendazole and levamisole are commonly used, taken orally, 1 tablet per 5 pounds, once a day for 3 days, which is effective against roundworms, pinworms and hookworms. Mebendazole is effective against roundworms, pinworms, hookworms, whipworms and nematodes. Compound Mebendazole (Quick-acting Intestinal Chongqing) is a combination of mebendazole and levamisole hydrochloride. Take 2 tablets. However, some dogs have blood in their stools, and the reason is unclear. Praziquantel can treat tapeworm infection, 10 to 20 mg per kilogram of body weight can be taken orally once. For anti-trichomoniasis, you can choose metronidazole. Sulfa drugs can only prevent coccidia infection, and amprolium hydrochloride can be used to treat coccidia.

Preventive measures:

Pay attention to deworming the dog's body, usually at least once every 3 months.
