Some sites that contain helpful information for dog owners in the area. Once again, keep in mind that I am only familiar with MD resources. If you have a site you would like to list for your area, please leave a comment at the bottom.
My favorite place for Monty to go to daycare or boarding (I take several long trips a year) is Happy Hounds Lodge. http://www.happyhoundslodge.com/ If you need any info don't hesitate to email me. They are located in Mt. Airy, MD but offer pick up and delivery service to the No. VA and MD area.
