We will help you humanely change your dog's behaviour


Diamond Dog Behaviour and Training is focused on providing first-class dog training and behavioural services, including an in-depth assessment, behaviour modification and training, with ongoing advice and support. 


We use our own controlled, stress-free secure large professional dog training area. This is important because you cannot change your dog's behaviour by continually placing the dog in an environment in which it is reactive; behaviour needs to be modified first in a controlled environment, and then carefully reintroduced. 


These are just some of the issues and problem behaviours we can help positively change:


Dog-dog aggression, aggression toward people inc biting, lunging, lack of socialisation, snapping, growling, mouthing and nipping.

Excessive barking , over-excitement, jumping, fearfulness,  phobia, play deficit. 

Rescue/rehab anxious dogs- including fear of other dogs, people, and environmental factors, including vehicles, etc. 

Play biting, protectiveness (food, toy etc, resource guarding) rebellious type behaviour, territorial aggression, separation anxiety, inappropriate toileting including marking.
