The 2019 American Animal Hospital Association Canine Life Stage Guidelines divide the dog's lifespan into four stages.  My post focuses on the behavioural aspects of each stage. As well, there are new guidelines from AAHA on the age at which dogs should be spayed/neutered, depending on their size. Learn more in the life stages of dogs.
