Can anyone tell me what animals don't engage in REM sleep at all, and are there any that don't sleep at all? Thanks...

In dolphins, whose newborns are almost completely functional at birth, almost no REM sleep exists after birth.

They do have REM sleep. There was an interesting article in the NY times last year. Some animals (ducks for instance) only shut down half of their brain at a time, so they are half awake, half sleeping. Others only go through 20min or so of sleep a night.
Everything needs sleep. Even insects rest. Sleep is a time for the metabolism to slow down and muscles repair themselves etc.

Yes, my dogs do, it lasts for about 2 or 3 minutes, if undistributed.
