I have a service dpg and according to the ADA one task is all that is necissary but most people with disabilkties need more then one task. A dog also must be trained punlic access stuff like socialisatio with all types of people. Elevators stores ect. And basic obedience and potty trained. Starting fromcq puppy this can take 18 months since dlogs go through fear stages. A bark is a bit disruptive as a signal. How about shapinng it to a pawing on your leg or a nose touch on your hand?
It's also important to remember a dog that is there oonly for comfort and does not do tasks to help with disabilities are not considered service dogs. Neither are dogs that do aggressive protection work or are growly or bite.
I would say Lydia your dog is at least an in home service dog. I am sure youvcan teach it somectasks related to dissociateisation.

and comgrats Anderson! I know how hard is to train your own. Sophie is my fifth but the first i trained on my own
I love having Sophie. She does some deep preassure stuff for me. Alongwith stuff for my physical disabilities. Yes i do feel safer with her as we are a team. It is a nice bonus!
