"First celebrated in 1999, Take Your Dog To Work Day was created to celebrate the great companions dogs make and to encourage their adoption from humane societies, animal shelters and breed rescue clubs. This annual event encourages employers to experience the value of pets in their workplace for this one special day to promote pet adoptions.
"On June 26, 2009, businesses, animal shelters and pet-care professionals from around the world will work together to better the lives of shelter dogs everywhere. Thousands of businesses will open their doors to employees’ pets on this day in celebration of the great companions dogs make."
This sounds like fun to me, though I don't have a dog anymore. When we first got Zoey, I brought her to work with me for the first month or so that we had her. That was a lot of fun, and people seemed to really enjoy having her there! Of course it was only temporary - once she got old enough I left her at home and came home at lunch to take her on a short walk. We always talked about having a "Take Your Dog to Work Day". Too bad I didn't know about this then - it would have been fun to try and implement! (There were a lot of dog lovers at my company at the time.)
Other companies are getting into this too. If you live in Stanleyville, NC, Chick-fil-A is offering free "Waggy Deals" for your dog tomorrow if they come through the drive-through. You can see more stuff like this if you check out Take Your Dog's Twitter page.
Of course not everyone thinks this is a good idea. I came across this article written by someone who dislikes the concept.
If you bring your dog to work tomorrow, you can upload pictures to Flickr with the tag "dogsatwork". You can also browse everyone's pictures here.
