"Las-sie! Come home!"
Mark, you're a Collie!
No bones about it, you're a loyal, nurturing Collie. A sensitive breed, you're always approachable and very in tune with others' feelings — just like Lassie! Because of your empathetic nature, you tend to be the group psychologist to your circle of friends. Your faithful, easygoing, steadfast personality makes you a wonderful confidant; people love to come to you with their troubles. Bottom line? You're a star at interpersonal relationships and have a knack for making new friends and acquaintances wherever you go. After all, what's a Collie without a flock to look after? Since you're so giving, your buddies might not realize that you need them just as much as they need you, so make sure not to neglect yours truly. Everyone deserves some "me" time. Woof!
