What are the causes of a high neutrophil count in dogs?

A high neutrophil count in dogs can be caused by a variety of underlying medical conditions. Here are some of the most common causes:

1. Infections: Bacterial and viral infections are common causes of a high neutrophil count. When the body is fighting an infection, it releases neutrophils to help combat the infection.

2. Inflammation: Neutrophils are also released in response to inflammation, even non-infectious inflammation. This can be caused by conditions such as allergies, autoimmune diseases, or trauma.

3. Cancer: Certain types of cancer, such as leukemia and lymphoma, can also lead to a high neutrophil count. This is because cancer cells can release substances that stimulate the bone marrow to produce more neutrophils.

4. Stress: Stress can cause a temporary increase in neutrophil count, especially in dogs that are already predisposed to high neutrophil counts.

5. Certain medications: Some medications, such as corticosteroids, can cause a decrease in neutrophil count, while others, such as chemotherapy drugs, can cause an increase in neutrophil count.

It's important to note that a high neutrophil count is not necessarily a cause for alarm. It can be a normal response to an infection or inflammation. However, if your dog's neutrophil count is persistently high or is accompanied by other signs of illness, it's important to see a veterinarian for further evaluation.
