7. Miniature Donkey
This neat little docile donkey is only around two or three feet tall, but it costs $1,500 to $2,000, and around $900 annually to care for it. It is at least easy to train and gets along well with kids and other pets.
It needs a stable to shelter it, and quality grass or grain hay for a high fiber, low protein diet. Donkeys tend to need the same vaccinations as horses, and hooves should be trimmed every other month.
