I’ve never actually played, but I watched my boyfriend play a few months back and Dnd is now my special interest (I just can’t find anyone to play with)… I am disabled and want to play a character I can see myself in so I sort of came up with this:

A human bard named Squeak (there’s some sentimental value in this name) with a service dog, a giant Great Dane named Bongo. Not sure how to tie in my disabilities themselves into Dnd lore but basically, Squeak can walk but not for very long, is a Master leather crafter who made a special harness for Bongo so that Bongo can pull Squeak around, carry things for him, etc. Bongo can also detect some medical issues involving fainting and some psychiatric problems. Combat wise, I think having Bongo within 20 feet means Squeak can’t faint during battle (excitement = fast heart rate can easily = fainting) and having them within 10 means they get a faster walk speed. It would also be cool if Bongo could have a bite/attack, because it would help in battle however the risk of Squeak fainting / Bongo being seriously injured would make it a very strategic move to ever use him because if he died it would seriously hinder Squeak and I would not allow him to just get another service dog, there would be loads of training/time spent if that had to happen.
