A dog was featured in the first video posted on Instagram.
The animal belonged to Instagram co-founder Kevin Systrom, whose early test content helped demonstrate what the service could do before its public launch. The dog became part of Instagram’s origin story because the platform began as a small photo-sharing experiment rather than the enormous video-and-social network it later became.
The earliest posts are sometimes described imprecisely. Systrom’s famous first Instagram post was a photograph of a dog near a taco stand in Mexico, while co-founder Mike Krieger also posted early test material. These details can cause confusion when people ask about the first photo, first post, or first video separately.
Instagram initially focused on square photographs and filters. Video arrived publicly in 2013, originally with short clips, and the service gradually expanded into longer uploads, Stories, live broadcasts, and Reels. The dog answer remains the key identification, even though the earliest content is often discussed as part of Instagram’s broader first-post history.
