Why does Minnesota Valley Humane Society euthanize animals?

The majority of the animals euthanized at our shelter are ill, very old, or too aggressive to be placed for adoption. Most of these animals are never put on our adoption floor, and are euthanized soon after arriving at the shelter. Minnesota Valley Humane Society is an open admissions shelter, which means we will always accept owner-surrendered animals, even when we are full.
