The "ex" is obviously human debris, but the family that tried to keep the dog isn't much better. I don't care how "bonded" the kids managed to get in 10 days. It's a wasted opportunity where the family could have taught the kids to do the right thing despite their 'feelings'.

Exactly. What about telling the kids they have a big responsibility, to take good care of a soldier’s dog until hopefully he makes it back home?
