Can a dog have Down’s syndrome? Simply put, the answer is no. The condition of Down syndrome has not been described in dogs. Three explanations are possible: These types of chromosomal abnormalities typically lead to early death in dogs.

How long do Down syndrome dogs live? In some cases, it may even kill puppies who are abnormal, such as the ones with Down syndrome. The mother attempts to eliminate the sick puppy to isolate him from the rest of its litter. In general, dogs with this disorder live for an average of five years while healthy ones live for 10 to 15 years.
How do dogs get Down syndrome? There are some distinct genetic differences between humans and dogs—in particular, that humans have 23 sets of chromosomes while dogs have 39.
