A Case Of Multiple Behavioral Disorders In A Dachshund With Early Environmental Deprivation

Abstract

Environmental conditions during critical developmental periods play a fundamental role in the behavioral development of dogs. Individuals subjected to sensory deprivation and limited social contact may develop persistent behavioral disorders in adulthood.

This paper describes the case of Drago, a two-year-old intact male standard wire-haired Dachshund, raised in a kennel environment during the first four months of life, who exhibited: fear-based defensive aggression toward a family member, predatory-like behavior toward children, intolerance to handling with defensive responses, and learned demand barking.

The multimodal therapeutic approach included: environmental management, family education on communication signals, systematic desensitization to handling, structured play activities with children, artificial den training, and differential reinforcement. The intervention emphasized predictable routines, respect for tolerance thresholds, and controlled gradual exposure.

After eight weeks of weekly sessions, significant improvements were observed: reduced frequency and intensity of aggressive responses, decreased chasing behavior, improved tolerance to handling, and reduction in demand barking.

This case highlights the behavioral consequences of early environmental deprivation and the effectiveness of a multimodal behavior modification approach calibrated to the specific etiology.
