Bell, Beagle/Lab Mix
Although Bell lives inside and sleeps under the covers every night, dogs can have a significant effect on an ecosystem. Over time, humans have domesticated dogs into trained house pets but at some point in time, they were all wild animals. When dogs kill other animals, such as mice or birds they are contributing to the terrestrial ecosystem. They are becoming secondary consumers.
