Desensitisation is a behavioural modification method that exposes your dog to their phobias in a very gradual, low-level approach that builds over time in order to train them not to respond adversely.
The use of desensitisation as a training method is highly advised if you want to assist your dog overcome its concerns.
Desensitisation training may help a dog overcome its fear of anything by making it associate that item, sound, or person with neutral associations.
Your dog may benefit from desensitisation by learning that the object of its phobia is not really dangerous.Training in desensitisation and counterconditioning are often employed together.
This may take some observational skills on your part but once you determine what it is, you can begin the training by introducing your dog.
Sometimes the dog will show subtle signs that then escalate and appear to be in reaction to something that is actually not the trigger.
For example, if a dog is nervous about the mail man but then seems to bark and become aggressive toward a housemate or person in the house.
