Your city (or maybe your county, because I'm not sure about Oregon's restrictions) will have that information for you. You need to ask about getting a kennel license. That should be your first step. Licensing restrictions will dictate the majority of things, depending on where you live.
Keep in mind that you will have to pay a separate licensing fee annually for each dog (over 4 months or 6 months, depending on your area), and a little higher rate for each one that is intact.
