The rabbit could not turn, and as the white teeth broke its back in mid air it shrieked as loudly as a stricken man may shriek. At sound of this, the cry of Life plunging down from Life's apex in the grip of Death, the fall pack at Buck's heels raised a hell's chorus of delight. (3.35)
The savagery of the wild necessarily ties happiness with death.

Over the whiteness and silence brooded a ghostly calm. There was not the faintest whisper of air—nothing moved, not a leaf quivered, the visible breaths of the dogs rising slowly and lingering in the frosty air. (3.37)
London uses descriptions of the environment to describe the moods of the dogs, as though the two were connected.

It was beautiful spring weather, but neither dogs nor humans were aware of it. Each day the sun rose earlier and set later. It was dawn by three in the morning, and twilight lingered till nine at night. The whole long day was a blaze of sunshine. The ghostly winter silence had given way to the great spring murmur of awakening life. This murmur arose from all the land, fraught with the joy of living. It came from the things that lived and moved again, things which had been as dead and which had not moved during the long months of frost. The sap was rising in the pines. The willows and aspens were bursting out in young buds. Shrubs and vines were putting on fresh garbs of green. Crickets sang in the nights, and in the days all manner of creeping, crawling things rustled forth into the sun. Partridges and woodpeckers were booming and knocking in the forest. Squirrels were chattering, birds singing, and overhead honked the wild-fowl driving up from the south in cunning wedges that split the air. (5.50)
Regardless of the hardship endured by man or by dog, the natural world goes on.
