Old pull-along dog toy, Kouvalias, Greece

Adorable vintage toy, a pull-along dog with its head and tail mounted on springs, in glossy red and black wood (the photos sometimes show it as orange, but it is indeed bright red). It was made by the Greek company Kouvalias (label still present underneath). Apparently, it is quite rare and this one is older than some that have the label stating "CE"; it probably dates from the 1970s. It is in generally good condition, sturdy, with no breaks, but does show some signs of its age: several paint chips on the tip of the nose and on the wheels, a small missing piece on the eye (sticker?), signs of use on the wheels, slight patina on the metal spring, and various small marks. It measures 16 cm in length, 10 cm in width, and 12 cm in maximum height.
