Aggression

27.8K
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

Borderline Personality Disorder

38
Borderline Personality Disorder is a complex and multifaceted mental health condition characterized by pervasive instability in interpersonal relationships, self-image, emotions, and impulse control. This instability manifests in extreme emotional reactions, fear of abandonment, and self-destructive behaviors. The disorder significantly impacts daily functioning, often leading to distress in both personal and professional domains.

Conduct Disorder

31
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

Summary

Border Collie agility dogs have high injury rates. Jumping at or below shoulder height, early jump training, and frequent competition increase injury risk, highlighting the need for safer training practices.

Area of Science:

  • Canine Sports Medicine
  • Veterinary Orthopedics
  • Animal Biomechanics

Background:

  • Border Collies are the most prevalent breed in canine agility competitions.
  • This breed exhibits a significantly higher reported injury rate compared to other breeds in agility.
  • Understanding injury risk factors is crucial for this popular working dog breed.

Purpose of the Study:

  • To identify demographic, training, and competition variables linked to injury risk in Border Collies.
  • To investigate factors associated with prolonged injuries (lasting over 3 months).
  • To test the hypothesis that higher jump heights and national/international competition levels increase injury risk.

Main Methods:

  • An internet-based survey was used to collect data from Border Collie owners.
  • A logistic regression model with backward selection was employed for data analysis.
  • The study included 934 Border Collies, with 488 reporting at least one injury.

Main Results:

  • Jump height relative to shoulder height was significantly associated with injury risk (both above and below shoulder height).
  • Other risk factors included competition frequency, national-level competition, age of starting specific jumps, breeder acquisition, and handler age.
  • Prolonged injuries were associated with the age of starting elbow height jumps and having a veterinary assistant as a handler.

Conclusions:

  • Jump height relative to shoulder height is a critical factor in Border Collie agility injuries.
  • Early introduction to jump training before skeletal maturity may negatively impact musculoskeletal development.
  • Findings suggest potential for reverse causality in some associations, warranting further investigation.
