animal, beast
獣 centers on wild, non-human creatures: animals and beasts, often with a connotation of ferocity or untamed nature.
獣 is the modern simplified form of 獸. The older form combines 犬 (dog/beast) with a phonetic component on the left that also relates to hunting or wild animals. The modern simplification retains 犬 on the right and a reduced left side.
The right side is 犬 (dog), a familiar animal. The left side looks like a simplified snout and body. Together they form a generic beast: 獣 is an animal.
