Neutrophilia in dogs is defined as an elevated circulating level of neutrophils > 0.3 x 109/L.
In dogs, this if frequently associated with increased numbers of immature neutrophils. With overwhelming infections, degenerative neutrophils may be observed on blood smears (degenerative left shift).
Although neutrophilia is usually a result of infections such as sepsis, other causes include:
- Fungal infections - e.g. Aspergillus spp
- Viral diseases - e.g. distemper
- Immune-mediated diseases
