The Influence of Maternal Care on Stress-related Responses in Puppies, Canis lupus familiaris
Maternal care alters neurology and behaviour in mammals. However, little is known about the impact of maternal care in domestic dogs. Rapid neurological development occurs in dogs between postnatal days 3 and 16, yet maternal care within this period has not been thoroughly investigated. Knowledge of...

Maternal care alters neurology and behaviour in mammals. However, little is known about the impact of maternal care in domestic dogs.
