Dear Dr. Sala, can you explain why God let my dog get hit by a car and die?" There are some questions that even theologians struggle to answer. So should a parent tell a youngster than his dog is now with Jesus in heaven?   Or should he or she tell him that when animals die, that's it? Or what should a parent say to assuage the loss of a child's pet? Many adults do not really understand the bond that exists between a child and his pet. When I was a youngster I had a dog that was my constant companion, and when my dog finally died, I was a young man in college, but I wept when I got news that Coalie was no longer with us.
