This dog, Charlie, a 12-year-old German Shepherd-Collie mix, licked a four-month-old Chihuahua-Pug mix puppy lovingly. Charlie was attacked by a dog at a young age due to which he had faced PTSD so his pet parent had begun working with him to understand trust in situations of control. When Charlie saw Nova's ear getting accidentally nicked, he rushed to lick her wound and groom her. The sight gave a ray of hope to his pet parent who was happy to see him bonding with another dog.
