Thyra Powers, CATT, CTDI, CCC

ThyraI am a Certified American Treibball Trainer (CATT), a Certified Trick Dog Instructor (CTDI) and a Canine Conditioning Coach (CCC). I started looking into actively training dogs (besides Obedience for over 20 years) when I adopted a Border Collie rescue 7 years ago. All that energy! What to do with it! I now have two Border Collie rescues: Dixie (7) and Ozzie (5). I am currently competing with them in Treibball, Agility, Nosework and both are Trick Dog Performers. Dixie currently has her Excellence title and Ozzie has his Intermediate title in Treibball. I only use positive reinforcement training methods, and love the use of a clicker. I am very proud to say that Dianna Stearns, ATA president, was my instructor for many years in Treibball (including the CATT Academy), and I still see her as my mentor in this sport.Besides all that I have a M.S. in Biology, and just love all living things!
