On the bottom left is the start of the leash with a loop handle. It tails into another loop that’s shaped like an upside down teardrop, for where the dog’s head would go.
This Dog Leash icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 5,700 icons, all in the same style and quality.
