Is the viral video of "Titan" the giant dog authentic? No, that's not true: The creator of the original TikTok video clip labeled it "AI-generated" when posting it on July 27, 2025. Subsequent re-posts and lower-resolution copies did not keep the label and attempted to pass it off as real video of a real dog.
The video of the gargantuan dog originated in a July 27, 2025 TikTok video (archived here) posted by @remix.master with the following description:
Meet Titan, my uncle's legendary giant dog!
???????? This gentle giant has been breaking records ever since he was a puppy, he's always been bigger than all the other dogs in the neighborhood, and nobody knows why. Titan was actually abandoned as a baby because of his size, until my uncle found him at a shelter and brought him home. Now, Titan is not just a pet, he's family, and trust me, he eats as much as a horse and takes up half the kitchen! People come from miles around just to see him, and my uncle says he's the best friend he's ever had. Their bond is unbreakable, and every day is an adventure with the world's biggest, most loyal dog. #GiantDog #Pets #Animals #Dog
