What color are fleas on dogs? - in detail

Fleas, including those that infest dogs, are typically a reddish-brown or dark brown color. This coloration is due to their diet and the presence of blood in their bodies. When fleas feed on the blood of their hosts, such as dogs, they become engorged with blood, which can make them appear red or reddish-brown. The specific shade of red or brown can vary depending on the species of flea and the stage of its life cycle. For example, adult fleas are usually darker in color than their larvae or pupae. Additionally, fleas that have not fed recently may appear lighter in color compared to those that have just fed. It's important to note that fleas can also change color slightly depending on the environment and lighting conditions. However, regardless of these variations, fleas are generally recognizable by their reddish-brown hue.
