Why not use non-visual self-recognition to test for consciousness in an organism?
Reading the page you linked, I found this


  MSR test may be of limited value when applied to species that
  primarily use senses other than vision. For example, dogs mainly use
  olfaction and audition; vision is used only third. It is suggested
  this is why dogs fail the MSR test. (With this in mind, the biologist
  Marc Bekoff developed a scent-based paradigm using dog urine to test
  self-recognition in canines.[19][41] He tested his own dog, but his
  results were inconclusive.[42])


Emphasis mine.
