Dog Bites and Welfare: Understanding the Causes

Dog bites are almost always the result of welfare failures — pain, fear, or stress — rather than random aggression.

Key Facts

An estimated 250,000 dog bite injuries are reported in the UK annually
Children are the most common bite victims, typically bitten by familiar dogs
Over 80% of dog bites are preceded by recognized stress signals that were missed
Untreated pain is a leading cause of bites in dogs that have not previously shown aggression

Welfare Considerations

A dog that bites is almost always a dog that has communicated distress through other signals first. The welfare failure is in the missed signals, the pain that was not treated, or the situation of fear that was not recognized. Preventing bites requires addressing the welfare problems that create the stress response — not punishing dogs for the biting that those welfare failures produce.

What You Can Do

Learn to recognize canine stress signals including lip-licking, yawning, and whale eye
Never force dogs into interactions they are avoiding, especially with children
Investigate pain as a potential cause if a previously gentle dog shows sudden aggression
Seek behavioral advice from qualified positive reinforcement trainers if biting behavior appears
