NOTES ON THE REFLEXES OF PUPPIES IN THE FIRST SIX WEEKS AFTER BIRTH

Abstract

A postural reflex of the pinnae is present during the first 2 weeks after birth. When puppies over 3 weeks of age are suspended vertically by support under the shoulders, a definite posture is assumed. From birth to approximately 22 days, the "after-effect" of the head occurs during rotation; after this age only the normal adult reaction to rotation can be elicited.
