Just a simple question, but could it be that dogs that are not DM/DM yet still have movement problems, be afflicted with another unrelated and yet unknown degenerative disease? Another disease which works through another biological mechanism.
If so, wouldn't it be conservatively prudent to say that dogs which are DM/DM as well as dogs with hence so far undiagnosed condition are both at risk for some type of degenerative condition, and both at risk to pass those genes, known and unknown to litters?
Are the two conditions interchangeable, and if not, can't they be approached as two different 'illnesses', so to speak?
