I am sorry for your loss! I know exactly how you feel, I actually had a dog named Emily (Dachshund/poodle mix) who was in the SAME exact boat as your Emily. She was attacked by a husky/shepherd mix and she was not in good shape and we made the tough decision to put her out of her suffering, and have her euthanized.
This has not been a good year for me and other dog forum members
