Published in the Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, this study investigated separation anxiety syndrome (SAS) in dogs and evaluated the effectiveness of behavioural modification protocols. The researchers observed 112 dogs, of which 42 were diagnosed with SAS. From this group, 12 dogs participated in an intensive behavioural therapy program that emphasized owner engagement and detachment conditioning.
The study highlighted that the attachment phase between 3 and 12 weeks of age is critical for emotional development. Puppies separated from their mothers after 12 weeks were significantly more prone to developing separation anxiety, as the delayed detachment period disrupts normal bonding transitions. Dogs often transfer their early maternal attachment to their human caregivers; thus, emotional regulation after separation depends on the security of that bond.
Behavioural therapy protocols included gradual desensitisation, environmental conditioning, and structured detachment exercises. Owners were trained to reduce anticipatory cues before departures, use calm re-entry rituals, and increase mental enrichment. Biological monitoring revealed measurable changes: a decrease in serum cortisol, erythrocyte count, and cholesterol levels, alongside a mild increase in leukocytes and magnesium, collectively indicating reduced physiological stress and improved homeostasis.
Papuc and colleagues concluded that recovery from separation anxiety is an all-or-nothing process—there is no partial remission. Sustained success depends on consistency, owner commitment, and the integration of behavioural therapy into the dog’s daily rhythm. The research validated behavioural modification as a reliable and accessible treatment model, aligning with modern relational frameworks such as Invisible Leash, which view anxiety as an expression of attachment imbalance rather than disobedience.
