Dynamic K9s is owned and run by Charlotte Rundgren. Although dogs have always been part of her life, her first love was horses, and it was in the equine field that her ability as an animal trainer first became apparent. She became one of the youngest people to obtain BHSAI qualification from the British Horse Society and trained with top international dressage riders from the UK, Europe, and the USA.

After a period of travel, Charlotte settled in the USA and it was there that she first became involved in the sport of agility, gaining USDAA Agility Champion and Top Ten ranking with her Australian Shepherd, Shadow.

Charlotte was fortunate to be able to train with many internationally respected trainers, including Susan Garrett, Mary Ray, Stuart, and Pati Mah whilst developing her own training philosophies. 

Since migrating to New Zealand Charlotte has competed successfully, making four dogs up to champion or grand champion status. She continues her education and studies in several programs including Shape Up, Into Shape, Q-Me, and all of Susan Garrett’s online programs.

In 2017 Charlotte qualified as a Certified Professional Canine Fitness Trainer (CPCFT) and has gone on to develop her fitness programme to keep her dogs, and her student's dogs in top-notch condition.
