I came across some information in the Bottom Line on puppy lemon laws. There are currently 20 states, including Oregon, that have lemon laws that provide legal recourse to people who purchase animals from pet dealers, later found to have a disease or defect. You can view a chart that outlines the laws in different states on the AVMA web site.
Don't worry, Kendall doesn't need this. I just thought it was a good piece of information to share.
