Doves and Pigeons actually make excellent pets. They are attractive, quiet, unobtrusive, have a calming, gentle voice, are fairly easy to tame, generally healthy and hardy, active but not demanding, require little maintenance and are usually inexpensive. They are easy to breed and make excellent parents.
The main difference between doves and pigeons is based largely on size. Doves are generally sleeker and smaller with pointed tails, whilst pigeons tend to be larger and stockier with rounded tails.
