Off-screen. We are only told about his death, not shown any suffering or dying dogs. Body is not shown either. A rescued dog-turned-pet succumbs to chronic injuries from previous abuses.
This is a documentary that includes dogs being rescued from horrible abuse and neglect situations. The filmmakers themselves didn’t harm the animals in any way, but they are including pictures of real injuries, and we see the aftermath of the dogs still living with chronic troubles related to their history.
It is mentioned that some dogs have symptoms that include vomiting while they are recovering from injuries and sickness/infections. Nothing is shown or heard.
One of the stories revolves around a U.S. Marine who dealt with a ton of objectification while serving, due to being one of 5 women on a base with hundreds of male soldiers, many of whom felt she didn’t belong, and made her feel pretty worthless during her time.
