When a video surfaced on TMZ of a dog being mistreated on the set of A Dog’s Purpose, outrage spewed across social media — so much so that producers canceled the opening.

PETA called for a boycott of the film after watching the dog’s trainer literally forcing a German Shepherd into turbulent water. The defenseless dog was overpowered by him as he tried clawing his way out of the water. Meanwhile, people were laughing off-camera.

Now, the star of the film KJ Apa is speaking out on Twitter, saying, “First things first, I LOVE ALL ANIMALS and would never EVER condone inhumane treatment or abuse of an animal at any time. I was saddened to see the footage from the set of A Dog’s Purpose—a film I was honored to act in, in 2015. The video was hard to watch, and I understand why many of you have had the reactions that you did because I had the same ones. The footage is still being investigated, from my own experience, I only encountered cast and crewmembers who had unconditional love and respect for every single dog on set, and went to great lengths to assure their safety and wellbeing.”

TMZ also reports that crew members are now under investigation by Canada’s Chief Veterinary Office, and jail time is on the table of any wrongdoings are found.
