Hello, my name is Dr. Kara and I have over 20 years of experience as a veterinarian.
I am certain that your fellow has been immeasurable help to you and truly has been a life saver.
Unfortunately the only dogs that can be certified assistance dogs in the UK are those that are assistance dogs for people that are physically disabled, such as deaf or blind people, those in wheelchairs or that have medical problems that the dog can alert them to such as diabetics with low blood sugar. These dogs must have gone through a training program that has been qualified by one of the charitable organisations registered as members of Assistance Dogs UK.
To quote the government website ...
"Assistance dogs trained by members of Assistance Dogs UK will have formal identification and have been endorsed by the Department of Health, on the basis that the dog's high standards of training, behaviour, health and welfare are such that it should be permitted to accompany its client, owner, or partner, at all times and in all places, within the United Kingdom."
At this time there is no program to train dogs for, nor is their any certification process for dogs that help with emotional distress, such as PTSD.
