Choosing a dog trainer can be a daunting task. First and foremost, the depth of their knowledge and experience should be something you ask about. Have they ever raised a puppy themselves? Have they rehabilitated their own rescue dog? Are they certified and/or what is their education? How long have then been training dogs? What work do they do with their own dogs, or have they titled a dog? What do they do to push themselves to be a better trainer than they were the day before?

Our dog trainers are all hand-selected by Koru K9’s owners. All our dog trainers are highly experienced, dedicated, and successful trainers who have met our intensive screening process.
