Which of the following is NOT one of the three phases of Canine Ehrlichiosis?

The three recognized phases of Canine Ehrlichiosis are acute, subclinical, and chronic. Each of these phases represents distinct stages of the disease, characterized by specific clinical signs and risk factors.

The acute phase occurs shortly after infection and is marked by symptoms such as fever, lethargy, and decreased appetite. If left untreated, the disease may progress into the subclinical phase, where the dog may not show overt clinical signs but can still harbor the infection, potentially leading to further complications. The chronic phase is characterized by more severe manifestations of the disease, including signs of bleeding disorders and immune system dysfunction, which often occur as a result of the prolonged infection.

The term "intermediate" is not recognized as a defined phase in this disease's progression. Therefore, it does not fit within the established framework for understanding Canine Ehrlichiosis, making it the correct response to the question regarding which is not one of the three phases. It’s important to be familiar with the existing terminology and classification to grasp the progression and management of the disease effectively.
