Here is a good site to keep watching for newly proposed bills that could go on to become laws. Many people think that these types of bills won't affect them, but if you own more than one or two dogs, or if you are a breeder, you really need to watch out. These bills sometimes are pushed through so quickly and quietly, that most dog owners don't even know about the bill until it's too late and it has become a law.
February's update should have a lot of additions to each of the states proposed bills. I know Virginia already has 11 new dog/cat bills that were proposed this month and we still have 2 weeks left in the month for additional proposals.

On the left side of the website, is a list of area groups that you can join that talk about proposed bills and changes in current laws and it's pros and cons. I'm a member of the VAPetLaws group ... it's really opened my eyes and helped make me more aware of what's going on.
