I had not heard of the Yellow Dog Project before. Now I will keep an eye out when I take my best friend out for a walk. She's very friendly and always looking to meet new friends. But now I can recognize those who may not want a new friend. Thanks for the information.
Glad I could put new information out there. It really is an excellent idea because we use at all our big walks, so its an easy way for anyone my to identify, leaving our walks stress free and for everyone to enjoy.
