I don't have a problem with dying dogs, but I'm gonna have to take the opposite stand on this.
Whether or not there are other animals in worse condition or she was harming the animal -- it was against the law and she knew it. She'd been warned many times by other people so it's not like she was unaware. Regardless of the circumstances, it was still against the law. She shouldn't have knowingly done it.
Not that I don't think it was for a good cause or anything..........
