my dog has hundreds of tiny black round bugs full of blood. They come off of him where ever he is laying. What are they and how do I get rid of them
There are different species of ticks and before they have a full meal they are flat. All ticks fall off the host, they feed and then fall off to deposit eggs in the environment. When they are fed and engorged they are full like a bean. There is nothing else that would feed on a dog with the description you provide.
