The iDog is a line of electronic toy dogs produced by Sega Toys, first released in 2004 in Japan. The toy combines a plush-like body with a plastic head and features LED lights in the ears and other parts that pulse and change color in response to music or ambient sound. The device includes a small speaker and simple controls, and its core appeal is its ability to synchronize with audio: when music is played nearby, the LEDs animate to the beat, creating a dynamic light show. Some models offered a 3.5 mm audio input to allow external music sources to influence the light patterns.

Variants in the iDog line include the original iDog and several sub-models such as iDog DJ, iDog Studio, and iDog Mini. These later versions introduced additional features like more programmable lighting patterns, different form factors, and optional accessories, while generally preserving the sound-activated light display that characterizes the line. The iDog line was marketed internationally and became a recognizable example of 2000s electronic-pop toys, reflecting a trend toward interactive gadgets that combine music with visual effects.

In the years since its introduction, iDog has appeared in toy catalogs and collector markets and is noted for its distinctive design and the way it integrated music with light-based interactivity. The line illustrates Sega Toys’ approach to blending character-inspired aesthetics with participatory, audio-responsive technology. See also Sega Toys, electronic toys, and toy pets.
