( CNN ) Tampa police have arrested a pair of teenagers in last week 's shooting of a young pit bull mix that was left for dead . The 17-year-olds face aggravated animal cruelty and armed trespassing charges after tying the hound , now named Cabela , to railroad tracks and shooting her multiple times . Surveillance video from the area showed a group of individuals walking the dog along the tracks in the city 's Sulphur Springs neighborhood before later running away , said Detective Patrick Messmer . Neighbors heard gunshots and police were called . Cabela was purchased to be used in dog fighting , but she was n't any good at it so they wanted to get rid of her , according to Messmer . `` This appears to be an isolated incident , '' he said . `` It does n't appear that there was a large amount of dog fighting that goes on in the neighborhood . '' On March 5 , police found Cabela tightly tied to the tracks and shot three times -- twice in the neck and once in the shoulder . `` Nothing gets you ready ... to see a dog -- a helpless animal -- tied so tight to a railroad track around the neck that it 's literally pinned down , '' said Sgt . Rich Mills , who freed her . `` She was literally pinned down . She could not get away even if she tried . '' Once freed , Mills rushed Cabela to Tampa Bay Veterinary Emergency Center . Initially , it was thought the young dog would have to her right front leg amputated because the damage was so severe , but a metal rod was inserted and she 's recovering . In fact , Cabela 's already walking on her repaired leg . Rehabilitation will take four to six weeks , according to Dr. Jamie Davidson .
