single, alone, spontaneously, Germany
独 centers on being the only one: single, alone, or acting on one's own. The meaning 'Germany' is a specific abbreviation derived from the idea of independence or self-reliance.
独 is the modern simplified form of 獨. The older form combines 犭 (dog) with 蜀, which likely contributed the sound and the idea of a lone animal. The modern form replaces 蜀 with 虫, but the original meaning of singleness remains.
A lone dog 犭 beside a bug 虫: picture a single dog staring intently at one bug, completely alone in its focus.
For ドク, imagine a single dock extending into a quiet lake, alone and solitary: dock -> ドク, and the lone dock represents the kanji's core idea of singleness.
