Great article - so needed to be said! I am a dog owner and this is a huge pet-peeve (pun intended I suppose?) of mine. My dog eats other dog's feces and it is a process to come home from a walk and wash her mouth out, plus she has gotten worms from it. I know as her owner it should be my responsibility to keep her from doing it, but she is so fast I can't stop it all of the time (she is leashed). It is amazing how many people have no problem not picking up. I can't even imagine the time and stress that comes along with having to clean off your wheelchair. I never thought about that and I am sorry you have to go through that process. This is yet another example I can provide when I post on my neighborhood FB page about this issue (yes, I'm totally that person)
