She waited a week after the puppy was injured to do anything, poor animal was probably in pain the whole time. All she had to do was go to a pound and let them know she was unable to care for the dog, many places will have vets come in and donate time for animals like that. She wouldn't get the puppy back but at least it would get care.

But wait.... I thought not being able to afford caring for something was a perfectly valid reason to kill it?

As she should face charges for this hienous act of cruelty Lt Col Charlie Brown .
