also: ムクいぬ
shaggy dog
Refers to a dog with long, shaggy fur. The term is somewhat literary or old-fashioned; in everyday speech, 毛むくじゃらの犬 or もふもふした犬 are more common.
A shaggy dog is lying in the garden.
Katakana variant of the first part; less common.
Rare kanji spelling using 尨 (shaggy).
むく (muku) means 'shaggy' or 'bushy', combined with 犬 (inu, 'dog'). The exact origin of むく is uncertain, but it may be related to the mimetic word むくむく (fluffy, shaggy).
