What Ehrlichiosis in dog & How it's Spread?
Canine ehrlichiosis is a tick-borne disease caused by the bacteria Ehrlichia canis. It primarily affects dogs and is transmitted through the bite of an infected brown dog tick. This tick species is common in warm and humid regions, but it can be found in other areas as well.
When an infected tick bites a dog, the Ehrlichia canis bacteria enter the dog's bloodstream and infect white blood cells. The bacteria can then multiply and cause damage to different organs, including the spleen, liver, lymph nodes, and bone marrow.
While dogs are the primary host for Ehrlichia canis, humans can also contract the disease if bitten by an infected tick. However, human ehrlichiosis is caused by a different species of Ehrlichia bacteria and is less common than canine ehrlichiosis.
Although not all dogs develop into the chronic phase, ehrlichiosis can be life-threatening in some cases when it does occur. When dogs progress to the chronic phase of ehrlichiosis, making a diagnosis can be difficult because there is a wide range of serious symptoms.
When dogs are bitten by ticks carrying Ehrlichia ewingii, they are more likely to either be asymptomatic or display milder symptoms, such as a fever and swollen joints.
In addition, veterinarians may use specialized tests, such as the indirect fluorescent antibody (IFA) test or the enzyme-linked immunosorbent assay (ELISA) test, to detect the presence of antibodies to Ehrlichia bacteria in the dog's blood. However, these tests may not be reliable during the acute phase of ehrlichiosis, as it takes time for the antibodies to develop. As a result, veterinarians may perform follow-up tests or wait until the dog enters the subclinical or chronic phases to make a definitive diagnosis.
In addition to antibiotics, dogs with ehrlichiosis may also require supportive care, including intravenous fluids to prevent dehydration, pain management medication, and blood transfusions if they have developed anemia or low platelet counts. Dogs in the chronic phase of ehrlichiosis may require long-term treatment with antibiotics and ongoing monitoring by the veterinarian to ensure the disease does not recur.
Prevention is also key in managing ehrlichiosis in dogs. This can involve regular tick control measures, such as tick prevention medications and inspecting dogs for ticks after they have been outside in wooded or grassy areas. It is also important to limit exposure to areas where ticks are prevalent and to check for ticks on both dogs and humans after outdoor activities.
Use tick prevention medication: There are many tick prevention products available for dogs, including spot-on treatments, collars, and oral medications. These products can help prevent ticks from biting and transmitting Ehrlichia bacteria to dogs.
Avoid tick habitats: Ticks are commonly found in wooded areas, tall grass, and brush. When possible, avoid taking your dog to these areas, especially during peak tick season in the spring and summer.
Check your dog for ticks: After your dog has been outside, inspect their fur thoroughly for any ticks that may have attached themselves. If you find a tick, use tweezers to remove it promptly and dispose of it properly.
Maintain a tick-free yard: Keep your yard mowed and free of debris, such as leaf piles and brush, which can provide a habitat for ticks.
Regular veterinary checkups: Regular checkups with your veterinarian can help detect and treat ehrlichiosis early, before it becomes more severe.
By following these preventative measures, pet owners can help reduce their dog's risk of contracting ehrlichiosis and other tick-borne illnesses.

Symptoms of Ehrlichiosis in Dogs
When caused by the Ehrlichia canis bacteria, ehrlichiosis in dogs is associated with three phases - acute, subclinical, and chronic. The acute phase typically lasts for two weeks to a month and is marked by visible symptoms that appear one to three weeks after the infected tick attaches to your dog. During this phase, your veterinarian may find it challenging to diagnose the disease since your dog may exhibit non-specific symptoms, including lethargy, fever, and lack of appetite, and antibody evidence of ehrlichiosis may not show up in tests for the first couple of weeks.The symptoms of ehrlichiosis in dogs may vary, and some infected dogs may not display any symptoms at all. However, common signs of ehrlichiosis in dogs include fever, lethargy, loss of appetite, weight loss, and swollen lymph nodes. Other symptoms of ehrlichiosis in dogs may include joint pain, difficulty breathing, and bleeding disorders. In severe cases, the disease can cause organ failure and even death. If you suspect that your dog has ehrlichiosis or if your dog shows any of these symptoms, it is crucial to seek veterinary care immediately.

Diagnosis of Ehrlichiosis in Dogs
Veterinarians may diagnose ehrlichiosis in dogs by conducting a physical examination, reviewing the dog's medical history, and performing blood tests. During the physical exam, the veterinarian may look for signs of fever, swollen lymph nodes, joint pain, and other symptoms associated with ehrlichiosis. Blood tests may include a complete blood count (CBC) and a serum chemistry panel, which can help identify any changes in the dog's blood cells and organs.In addition, veterinarians may use specialized tests, such as the indirect fluorescent antibody (IFA) test or the enzyme-linked immunosorbent assay (ELISA) test, to detect the presence of antibodies to Ehrlichia bacteria in the dog's blood. However, these tests may not be reliable during the acute phase of ehrlichiosis, as it takes time for the antibodies to develop. As a result, veterinarians may perform follow-up tests or wait until the dog enters the subclinical or chronic phases to make a definitive diagnosis.
Treatment of Ehrlichiosis in Dogs
The treatment of ehrlichiosis in dogs typically involves a course of antibiotics to eliminate the bacteria from the dog's system. The specific antibiotic prescribed by the veterinarian will depend on the stage of the disease and the severity of the symptoms. In the acute phase, doxycycline is a common antibiotic used to treat ehrlichiosis, while in the subclinical and chronic phases, a combination of doxycycline and other antibiotics may be necessary.In addition to antibiotics, dogs with ehrlichiosis may also require supportive care, including intravenous fluids to prevent dehydration, pain management medication, and blood transfusions if they have developed anemia or low platelet counts. Dogs in the chronic phase of ehrlichiosis may require long-term treatment with antibiotics and ongoing monitoring by the veterinarian to ensure the disease does not recur.

It is also important to limit exposure to areas where ticks are prevalent and to check for ticks on both dogs and humans after outdoor activities.

Ehrlichiosis in Dogs is contagious to humans?
No, canine ehrlichiosis is not contagious to humans. Ehrlichiosis is a disease that is primarily transmitted to dogs through the bite of an infected tick. While humans can also contract ehrlichiosis through tick bites, they are typically infected with different species of Ehrlichia bacteria than those that infect dogs. Therefore, the risk of contracting ehrlichiosis from a dog with the disease is very low. However, it is still important to take precautions when handling an infected dog, such as wearing gloves and washing your hands thoroughly after handling them. If you suspect that your dog may have ehrlichiosis, it is important to seek veterinary care to ensure proper diagnosis and treatment.FAQs for Ehrlichiosis in Dogs
