About

Dianna has been training dogs professionally since 2011. She has done everything from teaching group training classes and private lessons, to specializing in working with fearful, reactive and aggressive dogs, to being a trial official and competition organization staff member.


Following a serious neck and back injury, Dianna was forced to retire from in-person dog training. But she was not ready to give up her passion! So, she created Pet Dog U, Dog Sport University and Scent Work University to provide outstanding online dog training to as many dog handlers, owners and trainers possible…regardless of where they live! Dianna is incredibly grateful to the amazingly talented group of instructors who have joined PDU, DSU and SWU and she looks forward to the continued growth of PDU, DSU and SWU and increased learning opportunities all of these online dog training platforms can provide.


In June 2021, Dianna and her business partner, Sean McMurray launched Cyber Scent Work, Inc., an organization that operates in the gray space between training and trialing in Scent Work. With Cyber Scent Work, Inc., handlers have the opportunity to earn Qs, titles and ribbons while also receiving helpful training advice regardless of whether they qualify or not! Be sure to check out Cyber Scent Work, Inc., you will be happy you did!
