I need closure over the loss of my dog?

Takes time - for EVERYONE. I yelled at my cat... a Persian with long white hair and blue eyes. He thought he was a dog. He would meow when he heard someone at the door and slept with me every night - I yelled at him for knocking over my glass of water when he was trying to rub against me. The next time I looked for him, he was under the couch. I think he died of a broken heart. I will NEVER forgive myself, but it takes time. Still hurts to talk about it. Best of luck to you. (((HUG)))
