Kevin May's clients are furry, four-legged, and full of needles by the time he's done with them.
May has been a veterinarian for 35 years. His passion for animal acupuncture started in college when he himself felt the benefits.
"One of my professors at Texas A&M gave us a new type of seminar on acupuncture and I've always had a problem with heartburn. He taught us a certain point to push in your throat, I did and my heartburn went away. That's when I put down my sandwich and started listening and I've been interested in acupuncture ever since," May said in an interview with CNBC's "Power Lunch."
