The bravery of a tiny dog protecting its 10-year-old owner from a coyote in Toronto was caught on camera.

The dog died in September at a private facility at New York’s Kennedy Airport used to hold animals from overseas that are denied entry to the U.S. by federal officials. The news was heartbreaking for a woman who says she was the owner-in-waiting for the female Yorkie. “It’s been really, really rough for me to deal with her death,” Rachel Hobbs, of Dayton, Ohio, said in a recent interview. A second Yorkie named Wonderful Baby Blue Diamond was under the care of a veterinary clinic suffering from an intestinal illness, according to court papers filed this week. “The question of who is responsible for any of these charges rests upon whether the seizure was reasonable and constitutional,” the plaintiffs say in court papers.
