I'd say you left behind a fantastic dog. For me the dilema would be - is it stealing to take a starving dog home feeding him and letting him love you for it? Since I have rescued 3 dogs and taken another from my buddy and drove hime to the pound, I sort of feel that whats good for the dog is the moral high ground.

Your dog will find you. It sounds like it found you. Well I hope this new puppy fills a void for you. Its amazing how much fun and love a dog is and how it will make your life more livable. I mean I can sit on the couch and drink my coffee in the morning and be bored, OR I can sit on the couch and drink my coffee with my dog pressed against me thumping her tail - its a lot more fun.

Remeber its a dogs job to get you away from your computer and out in the sunlight. I built my dog a pond and everyday she makes me play stick in it. Keeps her clean...
