Your story is a real tear jerker. I think it was apparent from the start that the young hunter had a good heart and it would be discovered that his reasons would be related to his beloved pet. It is a story that is very believable because of it's implication that children really don't understand death and that the loss of a pet does not necessarily bring any sort of greater understanding. It also underlines the fact that children are capable of a deeper type of caring, especially towards animals, than most adults ever exhibit.
The story could use a bit of grammatical editing to help it really deliver the beauty of the story. I think you will find that if you give it a bit of reworking that it can be an even more inspiring tale.
Your poem gave an overall chilling feeling, which I think is particulary right given the nature of it's content. The last stanza warms the reader, and the author up - the flurry of snow and pre-storm activity is at bay, and the worry is eased by warmth from stove and drink. The perfect setting for reading, or writing, poetry, wouldn't you say?
