Two struggling rescue dogs have bonded over their difficult pasts, reports The Dodo.
On May 3, Rescue Dogs Rock NYC posted a Facebook message about border collie Simon, comforting Sammie, the newest addition to the shelter.
The accompanying photo shows the duo gently touching paws.
While Simon is dealing with the skin disease mange, his new boxer puppy friend is reportedly in critical condition after undergoing medical treatment for the abuse he had suffered.
According to a fundraising page set up on YouCaring, "Sammie is a 3-4 month old puppy who...was shot in the head, dragged behind a car AND spray painted!!!"
While his gunshot wound has been successfully treated, there is concern about the injury sustained to two of his legs.
Authorities are not expected to pursue Sammie's case because he is considered a "stray."

SMITHVILLE, NJ - UNDATED: Lucy with Great Dane dog in Smithville, New Jersey. At two and a half pounds, six inches long and just under six inches tall, Lucy is the smallest working dog in the world. Tiny pooch 'Lucy' has been named by the Guinness Book of World Records as the world's smallest working dog. The little Yorkshire terrier is just 5.7 inches high and weighs only two-and-a-half pounds. She was handed the certificate in recognition of her work as a therapy dog with the elderly and disabled. Age three and six inches long, Lucy works in a program called Leashes of Love and visits hospitals, nursing homes and special schools in Smithville, New Jersey. The title is awarded according to weight - meaning Lucy smashed the previous record held by a six pound search and rescue dog in Japan. Even though she weighs less then 12 sausages, she now has a huge status among working dogs around the world. She is owned by Sally Leone Montufar, 56, who put her forward for the record.
