Momoa begins the video with a subtle howl in sync with his canine friends before he begins to narrate the current fight to save the aggressively hunted and slaughtered species.

Momoa shared the video on his Instagram page, captioning the post:

“Wolves remain under attack across the country. States like Idaho and Montana have declared a war on wolves authorizing the slaughter of up to 90% of their wolf populations. Earlier this year, a hunt in Wisconsin saw over 200 wolves killed in less than 60 hours. We must put a stop to these senseless killings. Join us, Jason Momoa, Leonardo DiCaprio, Iliza Shlesinger, Conrad Anker, Filipe DeAndrade and thousands more in our efforts to #RelistWolves.”
