Pets in Silkroad are able to help you in each different kind of ways.Usually pets have to grow from level 1if you buy them in shops or can be bought at more level if you buy them from other players.
You can summon animals to aid you on certain tasks. Most pets have to be bought with Silk,or Silkroad's private currency on the Item Mall.however, the Grey Wolf can be bought with either silk or gold respectively.once bought, they do not disappear. Wolves can die during combat and that will make them unable to be summoned. They can be revived with the 'Grass of Life' herb sold at each city's Stable NPC.
