Black Dog Looking Up Yellow Background 4K Phone Wallpaper

An animated black dog with large expressive brown eyes sits upright, tilting its head toward the upper right corner against a vibrant solid yellow studio background. The canine features smooth dark fur with subtle textural details on its floppy ears, upright posture, curved tail, and paws planted firmly on the lower surface. Bright lighting casts soft shadows beneath the animal while highlighting its cheerful profile and upward gaze in a clean 3D character design style. Optimized for mobile vertical displays, the clean yellow negative space in the upper and lower sections provides exceptional contrast for app icons, widgets, and lock screen clocks. The high-resolution 4K clarity ensures sharp definition along the dog's furry silhouette while keeping the minimalist background free from visual noise, making it an ideal background for daily smartphone use.
