Phalene or Papillon
There is three different ear varieties in the Papillon breed:
Papillon - Ears fully erect
Phalene - Ears dropped
Soft eared Papillon (Button ears) - Ears not fully erect nor fully dropped
Here are some examples of each bellow.
Ears are fully erect when alert
When alert ears remain fully dropped.
Soft Eared Papillon
Soft Eared Papillons or Button Ears come at different levels. On this example notice how the very tips of the ears remain floppy when the dog is alert. This variety is any dog who when alert the ears are neither fully up nor fully down.
All three varieties can be born in the same litter. All three can be Kennel Club registered and hold the exact same genetic testing standards. The only difference in the three varieties is the ears all other breed standards remain the same. It comes down to personal preference of each individual as to what variety of the papillon they favour as a pet.
