What do flea bites look like?

Sometimes, those are a little small to see with the naked eye, but they can have some secondary reactions. It's not uncommon for pets to be allergic to flea saliva, but we can see some secondary skin infections because of fleas. And so you might see red bumps, pimples, ulcerated areas, maybe some scabs, or things like that.

Flea bites may not always be visible, but when they are, they appear as small red dots, typically in the belly or thigh area where the hair is thinner. These red dots are caused by inflammation related to the flea saliva injected into the skin. When dogs have an intense inflammatory reaction to the flea saliva, they may chew, scratch, or lick the area, which can lead to further inflammation and infection called flea bite allergies.
