From the Herald Journal article:
Crosland allegedly talked to the three boys about death by drowning, saying it was faster and less painful than allowing it to starve to death on the farm, and in its weakened state, the puppy reportedly died quickly, Hansen said.
While this occurred at about 4:30 p.m., nearly an hour after classes were dismissed, Hansen said it was reported by a janitor who claims to have heard the puppy and entered the locked classroom where the animals are kept.
So the puppy did NOT die quickly and without pain.
Meanwhile, a biology teacher should know that animals need to be feed their correct diets, not whatever they feel like getting rid of. For example:

Snapping turtles are omnivorous in nature, feeding on a wide variety of live prey and also eagerly eating floating aquatic vegetation. In captivity, they feed aggressively on fish, worms, and crayfish, and will eat floating commercial pellets as hatchlings, juveniles, and adults. They eat so well, in fact, that they can become quite overweight in captivity. By not overfeeding them, and by keeping their cage decorations complex and giving them large enclosures, keepers can keep their snappers healthy and happy.
Fish, worms, and crayfish are not puppies. And they don’t cry out so loudly that a janitor feels the need to unlock a classroom to figure out what the problem is.
