It's such a hard choice! It'd be easier to just choose the one breed I'm not so crazy about. It's an absolute toss up between a Labrador or a Beagle. My first dog that I was able to permanently own was a black lab, her name was Angel. She was so playful, and of course loyal! I wouldn't mind having another lab. I'm totally crazy about Beagles, I've always wanted one, my love for them was encouraged when I saw the first Shiloh movie. Since then, I was never the same. Haha. Really, I still want one, and I'd either name him/her Shiloh or Snoopy.
Honestly, all dogs are great, and having any breed is a blessing. They teach you more than you're teaching them! (Loyalty.)
