This study investigated compulsive tail chasing in a Bull Terrier, identifying a seizure pattern and mild hydrocephalus. Anticonvulsant therapy was effective, suggesting a potential hereditary link possibly involving zinc malabsorption.

Area of Science:

  • Veterinary Neurology
  • Canine Behavior Studies
  • Neurogenetics

Background:

  • Compulsive behaviors like tail chasing in dogs can be challenging to diagnose and treat.
  • Understanding the underlying neurological and potential genetic mechanisms is crucial for effective intervention.

Observation:

  • A Bull Terrier exhibited continuous tail chasing, appearing hysterical and dissociated.
  • Clinical examination, electroencephalography (EEG), and computed tomography (CT) of the head were performed.
  • EEG indicated a seizure pattern, primarily in the temporal lobe; CT revealed mild hydrocephalus.

Findings:

  • Diazepam, an anticonvulsant, effectively controlled the tail chasing behavior.
  • Naloxone, an opioid antagonist, did not affect the behavior.

  • The dog was euthanatized due to subsequent aggression despite initial treatment success.
  • Implications:

    • The findings suggest a potential hereditary basis for this tail chasing behavior in Bull Terriers.
    • A possible link to zinc malabsorption is proposed as a contributing factor.
    • This case highlights the importance of neurological evaluation for compulsive behaviors and informs potential treatment strategies.
