This was inspired by Jenn's post about heart breeds, and I was wondering how many people have found their heart dogs? And I also had a few questions about heart dogs.... Can you have multiple heart dogs? What makes a heart dog a heart dog? Do you think that everybody has a heart dog at one point or another? How do you know when you have your heart dog? I love all of my dogs, but I'm pretty sure that I have not had a heart dog yet.
