Hello. Here is a link to a video about assistance dogs for autistic people. I hope it is helpful:
Assistance dogs for autistic adults:

The speaker in the above video can be contacted for advice or help about assistance dog training.
I would love to know about this too - I feel like an assistance dog would be a massive benefit to my life but it's hard to know where to start.
My psychiatrist has suggested I get an assistance dog
What does your psychiatrist suggested the dog assist with? Is it a companion dog or do you need it to help you with specific tasks?
Also - for the training of your current dog, were you using training guides when doing the training of the dog?
Dogs need consistency in their training so everyone in the house has to follow the same rules in treating the dog othewise it will follow the path of least resistance and can undo any hard work you put in.
ADHD can be challenging when trying such a patience based approach.
