It probably depends where you live. Depending on your towns or even state's laws, it is hard to say. If you are doing this for friends or relatives, you are probably fine. But if this is a "job" you should probably look in to it since everyone is sue happy these days.

Not in many locations. However, some cities may require you to have an occupational license, to be bonded, or to be registered.
how many dogs can I keep before I need a license
To get to school. If they walk, then they don't need a license, but it's recommended that they do.

You do not specifically need a license to train dogs for any police work, but you will need a license from the DEA so that you can obtain the narcotics for training. You may also look for what are called Psuedo sents, which are the "same" to dogs, but you do not need a license to obtain, or have them.
