My sons dog is sick and he thinks that his roomate had hit her in some way. He took her to the vet and the vet confirmed that she had either been kicked, hit, or injured in some way by brute force. He thinks that she will be okay and gave him some medicine to give her. But the vet can not explain at this point why she threw up some blood last night. She is doing better since the vet gave her a shot. But what can my son do to make sure that the roomate did not hurt her and will not hurt her anymore? He can not afford to move out and his dad will let him move in with him, but without the dog. I will let him move in with me but my landlord wont let me have a dog. Any ideas?????
