Do dogs have double eyelids? Some dogs have double eyelids and some have single eyelids. Because double eyelids are a dominant gene and single eyelids are a recessive gene, there are more dogs with double eyelids in the same proportion after mixing. The dog’s double eyelids do not count towards the dog’s character rating, so it doesn’t matter if there are double eyelids for the dog. The common double-eyed breed of dogs are Samoyed.
