The Russo-European Laika is described as being of medium size, males being about 54 to 60 centimetres (21 to 24 in) at the withers and females about 52 to 58 centimetres (20 to 23 in). The breed has prick ears and a sickle tail carried over the back. Temperament should be non aggressive. Colour can be any of the normal Spitz-type colours, but red and ticking on the legs is undesirable.
