Frog is the next dog to be taken. In what fashion does Henry tie the dogs the next night?

From the text:

Not only had his partner tied the dogs up, but he had tied them, after the Indian fashion, with sticks. About the neck of each dog he had fastened a leather thong. To this, and so close to the neck that the dog could not get his teeth to it, he had tied a stout stick four or five feet in length. The other end of the stick, in turn, was made fast to a stake in the ground by means of a leather thong. The dog was unable to gnaw through the leather at his own end of the stick. The stick prevented him from getting at the leather that fastened the other end.

Henry nodded his head approvingly. ch 2
