Ahh i am glad he is staying, dont take him to the shelter that young please. They will keep him for a while and see if someone claims him, which i doubt if they trew him out a window. If he feels scare at your home and is crying imagine that poor tiny puppy in a shelter Just breaks my heart, probably misses his mommy too. I am really glad you are keeping him, good luck and wish him the best. Cant wait to see pics.
