What do I need to know before applying for a PAD?

Hello, I am planning to move out in the next 2 years and to go to uni and think I would benefit a lot from a service dog, especially a PAD. I have diagnosed asd and complex ptsd as well as a few other things. I have a dog at the moment who is lovely but I feel as if I need some more.

Having a registered assistance dog who could accompany me to places like the supermarket or doctors appointments would help me feel a lot less stressed out. I also believe dbt and them “pawing” me when im thinking about a traumatic memory would be beneficial, crowd guiding etc. I’ve previously delayed doing these necessary things before due to anxiety, I hate having anxiety dictate my life.

I am currently living with my parents, and they wouldn’t be open to housing another dog. As well as this, my current pup is anxious so it wouldn’t be a good time to bring home a new puppy. He is an english cocker spaniel and is slightly reactive (lead frustration) with other dogs. Despite me trying to socialise him as best as I could as a pup, the behaviourist believes it is genetic unfortunately. The fact that my current dog is reactive has made me severely doubt my ability to train an animal, especially to such a level that a service dog requires.

So, owner training a dog (fully) is quite unlikely at the moment.

If an assistance dog is right for me, what do I need to know? My current dog’s breeder showed no red flags at all, yet my pup is nervous, should I look for pups specifically bred for temperament alone?? I was looking mainly at miniature poodles as uni dorms are tinyyy and as much as I love labs/goldens I don’t think they would have much room lol. I’ve also heard great things about poodles 🐩 as them being apart of the “fantastic four” and every one ive met has had a lovely temperament. I’ve found it quite hard to find specifically therapy line miniature poodles pups available, they are usually a lot more doodles around and theres a lot of controversy surrounding crossbreeds. Are there any other breeds I should consider? (Ideally fairly compact and not prone to many health issues)

What should I do? what should I research? I’m just feeling really lost right now. Thank you for reading :>
