Canine Ehrlichiosis is a canine septic infectious disease caused by cattle tick-infected dog E. canis. The characteristic lesions are wasting, most organ plasma cell infiltration, non-regenerative anemia and other lesions, which have strong spread and are often associated with other viruses, resulting in high mortality of sick dogs. You can choose to remove ticks and use antibiotic drugs. Comprehensive treatment.

Canine Ehrlichiosis is characterized by weight loss, infiltration of most organ plasma cells, and reduction of blood cells and platelets. In 1935, Donatien Moral Algeri discovered the disease, which was called R. canis. In 1945, German Moshkovski re-named it Canine Ehrlich’s disease. Later, the disease was reported in southern and northern Africa, as well as in Syria, India and the United States. The disease appeared in Chinese military dogs in 1999 and the pathogen was isolated.

Symptoms of Canine Ehrlichiosis

The incubation period is 8-12 days. Sick dogs have periodic fever, loss of appetite, mucus-purulent nasal discharge and eyes gums, anemia, and weight loss. Severely ill dogs vomited, swollen lymph nodes, eroded oral mucosa, edema of limbs and scrotum, ascites, pleural effusion and gastrointestinal symptoms. Some sick dogs have red patches on their armpits and groins, and they feel sensitive. German shepherds often suffer from bone marrow formation disorders and hematopoietic dysfunction, leading to systemic hemorrhage such as nose bleeding and intraocular hemorrhage and death. The course of disease generally goes through three stages: acute phase, subclinical phase and chronic phase.

Acute phase: lasts 2-4 weeks, mainly manifested as fever, decreased appetite, drowsiness, mucopurulent discharge from the mouth and nose, stiffness, inactivity, edema of the limbs or lower abdomen, cough or difficulty breathing. The disease resistance of the affected dog decreased, lymphadenopathy, splenomegaly, and platelets decreased. In addition, parasitic ticks can often be found on the surface of dogs in the acute phase.

Subclinical stage: Sick dogs die less frequently in the acute stage. Most of the sick dogs’ clinical symptoms gradually disappear and they enter the subclinical stage. Their body temperature and body weight basically return to normal. But hematological indicators are abnormal, such as thrombocytopenia and hyperglobulinemia. The sub-clinical phase can last for 40-120 days, and the dogs who are still unable to recover are transferred to the chronic phase.

Chronic stage: Sick dogs mainly manifest as pernicious anemia and severe weight loss. Clinical symptoms include marked splenomegaly, glomerulonephritis, renal failure, interstitial pneumonia, anterior uveitis, cerebellar ataxia, hyperesthesia or paralysis. Nosebleeds are common in dogs of long-headed breeds. Hematuria, meconium, and ecchymosis of skin and mucous membranes can be seen in all dog breeds. The blood picture is seriously abnormal, all kinds of blood cells are seriously reduced, and platelets are reduced. When the disease is co-infected with Babesia and Bartonella, the mortality rate is high. Puppies are taller than adult dogs.

Some affected dogs have round or oval hair loss or hair breakage lesions, which can merge into pieces when they occur in multiple places, with fine scales or obvious scab formation. If there is no secondary infection, itching does not occur. There are limited hair removal or papules, forming a small scab like blood scab. In some cases, the whole body is depilated and the skin is obviously thickened.

Treatment of Canine Ehrlichiosis

Intramuscular injection of long-acting oxytetracycline (0.1ml/Kg body weight) once every other day, three consecutive times. Secondly, doxycycline, tetracycline, sulfadiazine, etc. can also be used. Infusion therapy, relieve symptoms of anemia, supplement energy, enhance body immunity. For cases of decreased blood albumin, canine blood albumin is used intravenously.

To remove cattle tick: Firstly conduct a full body examination, remove the visible bovine ticks, and then subcutaneously inject doramectin and topical repellents to kill and repel bovine ticks.

After the symptoms were relieved, the medication and intravenous infusion were stopped, and then changed to continuous oral doxycycline (5mg/Kg body weight) for 20 days to completely kill the pathogens in the blood.

Improve diet, increase nutrition, and provide high-quality dog food. Oral blood supplements, such as blood supplements.

It is recommended to use environmental medicine to drive out cattle ticks in the environment.
