What do Dog Fleas Look Like?

They are very tiny dark brown,red or blackish colored insects. They are flat on both sides so you cannot squash them you need to keep this in mind if you catch one. Some people will try ripping them apart to kill them but in some cases they still use their front legs and try and walk away so it may be best to throw them in boiling water. They are very small about the size of the tip of a pin.
