So sorry for your loss, I do know what it's like, it's TOTALLY devastating. Definitely go after the owner of the dogs. File charges against him with your local law enforcement & animal control. Show them the pictures of the wounds to your babies & the damage these beasts caused. This jerk needs to be held accountable for his animals. Also, find out what your legal rights are if the dogs come on your property again, can you shoot them if they do. Again, so sorry for your babies, I too have lost babies to dog attacks.
