Looks like those Finnish dogs. How big do they run?

Finnish dogs are also laikas, from a Siberian-centered point of view (they are called "karelo-finskaya laika" in Russian), and so are Norwegian elkhunds, and Yakutian hunting dogs.
An average West Siberian laika is about as big as a labrador retriever, but normally more compact and longer-legged. Males are usually significantly bigger than females. Because it is a working breed spared from excessive interest from the FCI, their phenotype remains pretty variable. The West Siberian laika as a breed was created in state-run Soviet kennels from hunting dogs used by the Khanty and Mansi people of the middle Ob basin, so many dogs in our village are non-pedigree and yet they are typical laikas.
