Two things . 1 . What if the dog was abused while younger and rescued by its current owner ? You have no way of knowing whether a dog ' s scars were from 3 days or 3 years ago . You could potentially be taking a dog away from its rescue family that is much more knowledgeable about its history and background . 2 . Stop trolling . Dogs get loose all the time , for a variety of reasons . We had lawn guys that opened our gate to mow our backyard . They didn ' t know we got a dog because she was in daycare the day they came . When we came home , we didn ' t realize the gate was open so when the dog went outside to potty , she snuck out . That ' s not abuse . That ' s an honest mistake . Again you have no way of knowing why a dog is loose . Stop assuming the worst .
