If you saw my post "my dilemna", I struggled with my sweet Georgia passing about a month ago. She had 6 babies in March and I fell in love with the smallest girl. Right now, we have Chewy. I know how you are feeling. I was worried Chewy was going to be struggling, but he is doing better. He and I are going to get into an agility class as this should help him adjust and me as well. and that way, later when my husband and I decided to get another dog (which we will

), then I know we will be ready. I think my heart was hurting way too much to keep the smallest girl, which is why we are giving her to a good friend of ours (she lost one of her yorkies in Jan.) so I know she was in good hands.
I'd say if you don't feel ready for another one, I would wait. If a few months down the road you want one, then do it. I don't know what your life situation is right now, all I know is that it is a hard thing to go through. I also sought out a grieving counselor to help me (still am). I am very sorry about your babies, I am here if you want to talk/pm.
