Preventing separation anxiety in companion animals through appropriate training and habituation during sensitive periods is far more effective than treating established anxiety disorders.
Separation anxiety prevention welfare reflects the importance of early life experience in determining adult anxiety vulnerability. The sensitive socialisation period for dogs provides an optimal window for habituating puppies to brief, then gradually longer, periods alone before they have developed the dependence that drives separation distress. Graduated alone-time training establishes independence without distress. This prevention window, once missed, cannot be fully recovered - established separation anxiety requires intensive treatment. Preventing the condition is immeasurably better welfare than treating it, and requires only knowledge, patience, and early implementation.
