"WebEosinophils have round red granules and a light blue cytoplasm. Some species of dogs, such as Greyhounds, have vacuolated eosinophils (eosinophil granules lack myeloperoxidase and do not stain red). Their eosinophils can mimic monocytes but are far more vacuolated. Dog basophils have long, ribbon-like nuclei and faint purple granules. " - Cytoplasmic granules in eosinophils
