I searched for canine trisomy in the internet. It looks like
they can have a trisomy 1 whcih causes some types of cancers,
trysomy 13 (thyroid issues) and 18. The word is actually
trisomyism. Downs is trisomy 21. Humans are also sometimes born
with a trisomy 19. Each has it's own name after the doctor who
discovered them, Edwards, Downs, and Bach. Did not find any canine
with trisomy 21
