From the dyslexia and the bumping about it sounds like you may have some spatial awareness issues as well, or perhaps it is coordination problems as you suspect. Do you get turned about quite easily? That’s a pretty clear sign of problems with spatial awareness. I have a professor who is constantly saying things like “Your other left, Jay dear.” when we are walking down hallways and whatnot because I have similar problems.
As far as careers go, the kennel does indeed sound splendid for you. It’s a job that is never the same way twice. I find dynamic environments which involve a lot of interaction can be perfect for ADHD. Just be mindful that you don’t get in people’s faces too much, especially since you are worried about it. 
Just periodically check in on yourself and ask “is this too far?” I do this quite a bit as well and I feel it really helps because while I may have already stepped over the line a bit I haven’t gone too far and I can reel myself back in.
