Can dogs tell if a human has Down syndrome?

Yes, they can.
Downs Syndrome is defined by having a full or partial EXTRA copy of the 21st pair of chromosomes. Humans have 46 chromosomes (23 pairs) normally, so those with Downs have 47 total chromosome pairs. Dogs have 78 chromosomes (39 pairs), so it is possible to have an abnormal genetic mutation on their 21st pair of chromosomes. Therefore, every mammal that possesses 21 or more pairs of chromosomes can be afflicted with what has come to be known as Downs Syndrome.

More research needs to be done, but other genetic mutations on other chromosomes of all different mammals is possible, and could present in cognitive impairment similar to Downs Syndrome or could have different symptoms entirely.

Here is specific information from a technician to a veterinary neurologist on medhelp.com (Source can be found there, but answers.com will not allow me to insert the link here. Please do an internet search for this website, it only allows medical professionals to comment):

"It expresses differently in dogs than humans as the spinal cord connects directly to the back of the brain bringing signals in and then relaying them directly out again. It is most commonly noticed in puppies because the symptoms are most noticeable.
The common ones are:
Clumsy movement and ambulatory irregularities.
Poor vision
Hearing deficits
Inability to learn simple commands due to lack of ambulatory ability and poor eyesight and hearing"

***If you find information on various, non medical or non-scientific sites, from random people that cannot provide you real credentials, do not just BELIEVE what they say! You need to do more research and ask a professional.

Countries such as the UK, still use the term Down's syndrome, but shortening it to Down's is not using people first language, therefore, it is incorrect.
