ABANDONED. Fantasy, a boy and an invisible creature. spoiler alert.

[Hyde]

Hi. Please help me remember the title of a book i read a long long time ago. It is about a lumberjack and a boy and an invisible creature. The man encounters the creature in the woods. And it makes his life miserable. But later the boy gains control of it. The boy uses some sort of powder to make the creature visible. The Grollitian or something it would be. Dont remember very clearly.

I sort of remember that the man has 3 dogs too. And one of its name is "wind" because it is fast.
