That's true. I hope your kids are old enough to understand that sometimes tragic things happen to ones we love and a new puppy can help heal some of the hurt and loss your kids are feeling(you as well). When my kids were little, 10, 6, and 3 we had a yellow lab that everyone just adored. For some reason that at the time I did not understand I made my husband take me to the local shelter and we adopted our beautiful Molly a black lab that we still have. My husband thought I was crazy but I felt so strongly that we should have this pup. Well 2 mos later our beloved Cinnamon died. The reason we were led to Molly was now clear. She helped the entire family through a terribly tragic time. We had no warning that Cinnamon was sick. She just woke up ill and died within hours. My prayers are with your entire family as you go though this and whatever decision you make about the future will be clear to you when the time is right.
