The assessment involves several tests to ensure the suitability of the dog’s temperament and attitude for this type of work. It is the temperament of the dog that is paramount, size, breed, pedigree or cross-breed, first-owned or rescued are immaterial, the individual character and how the dog will react in all manner of situations is the vital consideration.
We would recommend that all dogs wishing to apply for assessment to are at the Kennel Club Good Citizen Scheme Bronze award (or equivalent) standard. The KC GCDS is accessible throughout the UK and is a great starting point for basic life skills as well as in preparation of the TDN assessment.
