Dog A.I.D. is a registered charity that helps people with physical disabilities train their own dogs. The training consists of a three tiered system. Level one, Companion Level, is basic obedience and some useful task training. For some people this is all they require. Level two, is the Advanced Companion Level, and for dogs with all round sociability; this is where dogs acquire further skills and continue the training in the useful tasks that are of help to their owner. At Level 3, Assistance dog Level, owners and their dogs go out into public places and practise putting these skills into operation. At the end of each level owners & their dogs are assessed and awarded a certificate issued from the office to show their achievements.
