There’s no question that therapy animals are some of the world’s most unheralded heroes. The ability of other species to help heal their human friends is nothing short of miraculous. And help, they do. From children’s hospitals to nursing homes to veteran centers, therapy animals do good works at all kinds of facilities and with all kinds of patients. These relationships benefit the animals and humans, both, and often open people’s eyes to the amazing abilities of animals beyond traditional roles as household pets. And today’s therapy animals aren’t just cats and dogs either.

These medical professionals come in lots of different species these days, from llamas to pigs and beyond. Many of them are rescue pets who come from difficult circumstances or abusive situations, yet they’re still able to offer unconditional love, trust, and compassion. Here are stories of some of the world’s most amazing therapy animals and how they helped their humans.

He’s known for curling up alongside patients and staying with them until they die, offering comfort and love, then quietly leaving the room.

When the horror happened at Sandy Hook Elementary, in Newtown, Conn., Spartacus, an Akita therapy dog, was among the first on scene. He remained on campus in the months that followed, offering Support and companionship to the traumatized students, teachers, and other responders. His impact even helped lead Connecticut government officials to pass a new law that mandates all victims have access to therapy dogs within 24 hours of a crisis.

But after his rescue and subsequent adoption, Hector’s new owners had him trained as a therapy dog. These days, Hector’s motto is “The only thing I fight is discrimination,” and judging by his Facebook page, he spends his time playing in meadows, sleeping in the sun, and visiting schools to teach kids compassion towards animals.
