I can't remember where I got this from but it is a sabre-toothed tiger painted up as a Snow Tiger. It could be a proxy for the Snow Leopard in the wandering monsters table, or even serve as an exotic war-dog for a wizard.
This Frostgrave plastic has a shield taken from a GW Ogre Kingdoms sprue. It is split and has been crudely bolted back together with metals strips. I like to think that this guy used to be a humble thug, but found (or stole) some leather armour and salvaged this broken shield and is trying to hire himself out as a man-at-arms for more money. Good luck to him...it's good to try to better yourself.
