Rosa canina, commonly known as the dog-rose, is a variable climbing wild rose species native to Europe, northwest Africa and western Asia.

It is a deciduous shrub normally ranging in height from 1–5 m, though sometimes it can scramble higher into the crowns of taller trees. Its stems are covered with small, sharp, hooked prickles, which aid it in climbing. The leaves are pinnate, with 5-7 leaflets. The flowers are usually pale pink, but can vary between a deep pink and white. They are 4–6 cm diameter with five petals, and mature into an oval 1.5–2 cm red-orange fruit, or hip.
