ESTHERVILLE, Iowa (KTIV) - For many, pets are considered to be part of the family. And an Estherville, Iowa family is glad to have their family back to full strength. As part of a nightly routine, Taylor Nissen let her dog, Tupelo, go outside so he could go to the bathroom. But one particular evening, he didn’t come back and Taylor got worried. She paced around, and looked for him, and eventually woke up her grandma to help in the search.
