sorry all previous answers wrong.
Trichoplax adherens is the smallest known animal with just a few cells in its body.

Those wasps mentioned, Dicopomorpha echmepterygis, are actually quite small. The wasp is the worlds smallest insect at 0.139 mm. The plankton is generally algae and therefore a protist or considered a bacteria in other cases. Head lice are 0.5 mm and are insects.
A dust mite is 420 micrometres, which is an arthropod and an arachnid, if that helps. I'm going with dust mite, final answer. A micrometre is one one thousandth of a millimeter.
I think an amoeba is considered a protist and not an animal. Bacteria are in their own domain and are not classified in the animal kingdom.

Bacteria and lifeforms like that actually don't count in terms of animals, because they aren't in the animal kingdom.
I think the answer might be fairy flies, but I'm sure there's something smaller yet to be discovered.
Fairy flies are wasps that are about 0.13 mm in length or less, and " Their tiny bodies, neatly packaged with complete digestive, reproductive, respiratory, and circulatory systems are actually smaller than a single-celled paramecium"
That's so cool :D

Probably Bacteria, they are of the size of 1 micron or 1,000 nm.
Below this is the Virus at 100 nm, which some people may not consider as "life", since it needs a Host to survive.

amoeba
EDIT: Wrong? But it's a single cell... How can it be larger than a multicellular animal?
"The most famous species, Amoeba proteus, is 700-800 μm in length, but many others are much smaller" -Wikipedia

would bacteria count? maybe some sort of bug, like those tiny red things that crawl all over the cement. they're literally smaller than the size of a crumb. maybe even smaller.

any unicellular being on earth should be the smallest.... might be still to be explored even

Well, plankton and protazoa and stuff are animals I think, and they are microscopic.
