Taxi Benke goes to school at the Northside Independent School District in San Antonio every day. He attends all his classes and some extracurriculars, too. So why shouldn't he get his class picture in the yearbook?

Well, there's the fact that Taxi is a dog, a half-Lab, half-golden retriever. He's 7th grader Rachel Benke's service dog, and he's been at her side for the past four years. Rachel has suffered from epileptic seizures since birth, including having two brain surgeries before the age of six, and Taxi was supposed to be a guide dog.

"We joke saying he's a guide dog dropout; he did not make the guide dog program because he has a cat distraction problem," Rachel's mom, Theresa Benke, told KEN5 San Antonio. "We were very overwhelmed, because at that time Rachel was afraid of animals."
