I wouldn't recommend either of those because they are franchised dog trainers, not behaviourists.
I suggest you go to your vet and get a recommendation for a veterinary behaviourist, or see one of the following:
K9Force (member here) at www.k9force.net or a veterinary behaviorist from this list. I hear good things about Dr Gaille Perry and Dr Kersti Seksel, both of whom are in Sydney.
Edited to sound a bit less short.
Hi Jamesanddean.
My name is Trudi Thorpe and I along with my business partner Julie Adams, run dogLOGIC dog training. I just thought that I should write to clarify Poodlefans misconception that we are "franchised dog trainers". We have developed dogLOGIC dog training from the ground, neither buying an exsisting business nor a francise. dogLOGIC comprises only of the two of us and both of us have had over 40 years experience between us in training and working with dogs. We are both accredited Delta CGC instructors, who as you may know are leaders in positive reinforcement tecniques. If you would like to discuss your problem with us, please feel free to contact us via our website www.doglogic.com.au or alternatively you may wish to search for other accredited Delta Instructors listed on the Delta web site at www.deltasociety.com.au.
Regards,
Trudi Thorpe
