A background image for a slide about the history of dogs, featuring a soft gradient transition from ancient to modern times. On the left, faint outlines of early humans and wolves are seen against earthy tones, symbolizing the domestication of dogs. As the background moves toward the right, it gradually shifts to brighter colors, with subtle silhouettes of dogs herding, hunting, and playing in various historical contexts. The design is minimalist and abstract, allowing space for text while conveying the evolution of dogs over time. Bright image
