Don't be so hard on yourself. You did the right thing, and you found the puppy a good home. It's not like you threw her to the wolves. That pup is probably eating steak right now. Besides the puppy will have the soccer moms kids to play with him/her all day. Your little cousin will get over it. He is not the one cleaning up puppy poop. It's obvious you love the puppy. I love them too. But, I can't have on in my home either. They need extra loving care, and alot of attention. It's a big responsibility. You tried, and it didn't work. The puppy will have a good life. And you don't have to clean puppy poop right now. Don't be sad. Picture him playing and running, and eating someone elses furniture. LOL
