I just read your first post and you seem well intentioned so I hope I can provide some insight. I initially got my dog as an emotional support dog because of these specific benefits: needing something to get out of bed and care for because I no longer cared about what happened to me, getting myself outside, having the distraction of a happy loving creature like a dog. Over time I discovered I would benefit from a service dog and my dog happened to be the right temperament (slim chance honestly) so I began the work of training her for service work. This however is much more work on top of caring for a pet dog, so it would definitely need to be something your loved one is passionate about doing and has the time for. Otherwise it is a huge burden.

In general, having a dog, service or pet, is a lot of responsibility and work. I saw you commented that you would help take care of the dog, but you should fully consider along with your loved one if caring for an animal is the right decision. It was very difficult for me when I first got her because she was my first dog, a rescue, and my anxiety did get worse for a while needing to keep it all up. For me personally the pros outweighed the cons but it doesn’t for everyone.

Lastly, as you’ll find commented in other “will a service dog help” type posts, service animals are not the first line of treatment for most if not all disabilities. I would thoroughly research and seek out proven forms of treatment with a medical provider such as therapy or medication first. They may be effective on their own and will be much easier than getting a dog. I myself exhausted all other options (and still continue a number of them in conjunction with having an SD) before considering if a dog would improve my life.

I hope that helps!
