Have you found your "heart dog" yet?

[PWCorgi]

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.
