I don't ever want to know anyone that can be that cruel. It's hard to believe someone would do something like that. A hawk could have picked it up. I'm hopeful the pup will find a good home. You were so nice to take care of it. I'd be so angry too, just realizing how mean people can be. I'm glad I'm a dog person. People scare me!!
Please keep us posted so we know how the pup is doing. He looks like he has some boxer in him/her. What a little cutie.
