Your owner abandoned you because he or she didn't want you anymore.
I'm going to take better care of you than your former owner did before.
You've been abused because you have a couple of gashes on your head.
You've had a hard life and it's been a while since you were last fed.
I'm sorry that your former owner was so crude.
I'm going to the refrigerator to get you some food.
After I take you to the vet, I'm going to give you a loving home.
I'm going to give you lots of hugs, you're no longer alone.
