Human-directed aggression is common in pet pigs. Having another pig in the household significantly reduces aggression, suggesting companionship is key for pet pig behavior management.

Area of Science:

  • Veterinary Behavior
  • Animal Welfare
  • Pet Husbandry

Background:

  • Human-directed aggression is a frequent concern in pet pig ownership.
  • Understanding factors influencing aggression is crucial for owner-pig relationships and pig welfare.

Purpose of the Study:

  • To investigate associations between human-directed aggression in miniature pet pigs and factors including sex, neutering status, weaning age, presence of other pigs, and environmental enrichment.

Main Methods:

  • An internet survey was administered to 222 owners of miniature pet pigs.
  • The survey collected data on pig demographics, social environment, enrichment, and aggressive behaviors.

Main Results:

  • Aggression was reported in 64% of pigs; frequent aggression occurred in 31%.

  • No significant associations were found with sex, neutering status, weaning age, or environmental enrichment.
  • Pigs housed with at least one other pig showed significantly less frequent and less common aggression.

    • Conclusions:

    • Human-directed aggression is prevalent in miniature pet pigs.
    • The presence of a conspecific (another pig) is a significant protective factor against aggression.
    • Promoting social housing may be an effective strategy to mitigate aggression in pet pigs.
