Oh Jen, I'm so sorry. It's never easy. I know how much it hurts, but I think a puppy is a wonderful idea. I know Katie would want it, she'd be happy. You have enough love in you to keep loving Katie, and to share your love with a new puppy. I also think a new puppy would help Codie. He lost his sister, one of his best friends. Your husband sounds so sweet, he knows you didn't mean anything. He understands you're just hurt, I'm sure he's hurting too. I think you should follow your heart, and do what you feel is right. Good luck, Jen. And know we're always here for you.
