37-year-old Justina Robinson, of Erie, Pennsylvania, has been arrested after she beat her 11-month-old service puppy, Izzy, with a hammer.

The dog survived the attack but sadly had to be euthanized due to the severity of his injuries.

“He was an 11-month-old little chocolate lab retriever mix and to see the pain and anguish in his eyes and in his face, thinking what is happening to me, is gut-wrenching,” Nicole Bawol, Executive Director of the Erie Humane Society, told Your Erie. She may have been attacked by another animal, or by a human. All that was certain was that the puppy lay helpless, unable to move and bleeding profusely from her neck on a large pile of rocks near a drain ditch. She also cried out in utter distress.
