have a service dog. She is small and is trained to mitigate some of my PTSD situations and hallucinations. However, It is very helpful to have some other tasks that she can't perform due to her size. I am looking into getting and training another service dog to mitigate some of the needs I have regarding the PTSD and other psychiatric symptoms mostly for balance and help pulling me out of hallucinations if I am triggered in public and feel dissociative and threatened. Is it legal for me to train two service dogs for mitigating the limitations I have for similar tasks they'd be performing? It is very confusing and I am unsure of how to train a smaller dog to help me with my balance and neurological aspects of the PTSD symptoms though my current service dog handles my needs for the hallucinations. I'm more looking for a dog who's large enough to exert pressure on my body(calms the paranoia) considering my 35lb dog can't really help with that.
