No.
No. Not legally although it is generally preferred.
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.
yes
to kip it fit
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.
Uhhh... NO
Nope. Just put your dog on a leash and walk it
dogs needs at least 30 to an hour walk. small dogs do have smaller legs and may needs a little less walk than bigger dogs. but a dog is a dog and they need about once a day about 30-1hr
No, dogs don't have human emotions, they need plenty of exercise (about an hours walk) everyday....
