Dog Training and Canine Behavioural Management is completely unregulated in Western Australia! 

Ensure the Trainer does not use Fear or Force techniques.

You never need to be dominant, aggressive or forceful. You need to be confident, consistent, clear and calm.

There is no regulated standard for trainers and behavioural consultants, this means that anyone can claim to know what they're doing and present themselves to you as a Professional Dog Trainer or Canine Behavioural Consultant.  This is not only irresponsible it can be incredibly dangerous.

My advice to people that are looking for a professional to help them with their training goals are as follows.

If you are dealing with a serious behaviour issue that involves reactivity to any stimulus and there is even  

the slightest risk that physical or psychological injury could result then look for a trainer with a minimum of 

TEN years of experience, which also has specific qualifications in the areas that you need to be addressed. For basic behavioural and obedience training find a trainer with a minimum of FIVE years of experience.

For classes including puppy preschool look for a trainer that has a minimum of FIFTY hours of instruction experience of classes in that area. 

Ensure that they are a force-free trainer! I would encourage you to ask them to explain the progression of Applied  Canine Behavioural Science over the past two decades. 

If at any time you feel uncomfortable with anything that they're doing with your dog, IMMEDIATELY STOP THE CONSULTATION and ask them to leave and seek alternative assistance.

Make sure you research the service provider, their experience and their qualifications. 

Always CHECK their REVIEWS and ask for evidence of their experience.
