Hi, !
A fully trained, certified service dog can be quite costly, but there are programs to help people get dogs that meet their needs. Here's one organization -- https://canine.org/. And here's another -- https://caninesupportteams.org/. And here's another one -- https://k94life.org/. The information can quickly get a little overwhelming, so I don't want to inundate you with links and data.
While fully trained dogs can be quite expensive, you may have luck adopting a smart dog and investing in training the dog to do basic tasks for you. That's entirely doable and quite a few of our members have been able to train their pets to help them.
If you need more resources, please let us know.
Best, Erin, Team Member.
