Details
Ectodermal Displasia causes extremely thin and fragile skin. Puppies suffer from skin splitting and bleeding on the nose, footpads, ear time, lips and face even from gentle touch. If puppies survive for a longer period, even mild friction around the limbs causes damage and splitting to skin. Age of onset from birth. Most puppies do not survive, or are euthanised.

... Clinical signs occurred immediately after birth with spontaneous sloughing of the nose and footpad epithelium and bleeding of the ear tips if traumatized. Within 48 hours of birth, the lips and facial superficial skin layers also sloughed when rubbed dry or licked by the mother... exhibited waxing and waning superficial skin sloughing with erosions and fissures at areas of friction (axillae, groin, caudal tarsi, footpads), concave ear pinnae and mucocutaneous junctions (nasal planum, philtrum, lips, periocular area) (Olivry et al, 2012)
