I wonder also if dignity means different things to different dogs? For instance, I know many older dogs are completely mortified by having an accident. I posted a while back about Heidi "losing" poop in the house occasionally. When this happened, she would just look at me like "so what, deal with it." I'm not saying it wouldn't be a dignity issue if she gets to where she is lying in it, etc., but a small, firm accident really didn't seem to bother her much. Also, I know some dogs get along amazingly well using a cart, but I think for others it would signify a loss of dignity?
