I would def. get a vet's opinion on wether Molly has been neglected in writing! I would also take a few pics. to show the condition of Molly. I would gather all the info. I could that would support the fact the dog has been neglected. I also agree with Dixieland Dancer as far as talking politely with the owners to see if they will give Molly up. If your parents are supporting you and the people don't want to give Molly up than fight them and keep her! Good Luck!!
