An annexure to the BHARCS Conflict Resolution Framework.

Purpose and scope

This annexure provides guidance for cases where a community dog is reported as "aggressive." The term is often misused to describe normal canine communication such as barking or growling. Several dogs labelled "aggressive" are in fact defensive or stressed. For the purposes of this SOP, aggression refers only to repeated, escalated behaviour (multiple verified transdermal bites that break skin) that persists despite medical, welfare, environmental and behavioural interventions. The aim is to prevent misuse of the label "aggressive," which may risk public safety as well as result in the unnecessary destruction of sentient animals.

1. Defining aggression in dogs

Communication / defensive signals (NOT aggression): growling, barking, lip-lifting, stiff body posture, showing teeth, etc. are communicative tools used extensively by most animals to avoid conflict, and should not be misinterpreted as threat or aggression.

Single defensive incident (NOT aggression): animals subjected to cruelty, injured or unwell animals, and whelping mothers can react defensively (provoked behaviour). This is not aggression; such cases require welfare checks and community awareness.

Aggressive case (per SOP definition):

• More than two verified transdermal bites that break skin within a 3-month period;
• Incidents continue despite veterinary checks, welfare support, and environmental/behavioural interventions;
• Documented evidence confirms persistence;
• Verification of the species the bite came from, based on the species' teeth pattern (scratches are not bites).

2. Why do dogs show aggression? (Root causes)

• Sleep deprivation — no safe place to sleep, crowding, inability to regulate temperature → restlessness and higher probability of conflict.
• Fear / stress — harassment, cornering, sudden approach, crowding.
• Pain / illness — undiagnosed injuries, arthritis, dental pain.
• Resource guarding — defending food, resting places, or caregivers.
• Maternal instinct — lactating mothers protecting puppies.
• Irritability / overstimulation — noisy environments, high traffic, rough handling.
• Learned defence — repeated intimidation, stone-throwing, or attacks by humans.

3. Identification checklist

A. Early warning signals — NOT aggression (normal distance-creating communication): stiff posture · hard stare · growling / low rumble · lip-lifting / baring teeth · snapping without contact · lunging towards humans.

B. Escalated behaviour: multiple verified transdermal bites that break skin.

C. Context observed: around food · at resting/sleeping area · when harassed/cornered · near caregiver/puppies · unpredictable (details logged).

D. Possible root causes: medical issue suspected (refer vet) · resource guarding · maternal defence · fear/stress triggers · lack of adequate sleep · history of harassment.

Decision rule (to prevent misuse)

• If only A or C/D are ticked → defensive/normal behaviour, not aggression.
• If A is ticked repeatedly → escalating tensions; a species-specific behavioural expert can be involved to analyse further and avoid bites.
• If B is ticked once → single incident; manage with welfare, vet, and awareness.
• If B is ticked repeatedly and the criteria are met (two or more verified transdermal skin-breaking bites in 3 months, and vet + welfare + behavioural interventions already tried) → classify as an aggressive case and escalate per SOP.

Appendix — Scientific rationale

1. Behavioural science basis — dogs are conflict-avoiding by nature. Biting typically occurs only when other coping strategies have failed, often due to prolonged or intense sympathetic-nervous-system (SNS) activation without sufficient parasympathetic (PSNS) recovery.
2. Importance of root-cause analysis — international best practice (including WHO guidelines) stresses that without identifying and addressing the underlying cause, incidents may recur, even after relocation.
3. Common triggers — chronic stress from noise, harassment, or lack of safe resting spaces; irritability from inadequate sleep; guarding over limited resources; unintentional provocation (being cornered, startled, approached suddenly); pain or undiagnosed medical conditions.
4. Role of rest and safe space — a safe place to rest lets the parasympathetic nervous system activate, reducing stress hormones and enabling emotional regulation; moving resting places away from crowds prevents startle-response bites; positive human interactions boost a dog's sense of safety.
5. Education as prevention — misreading canine body language leads to unnecessary fear or confrontation. Public awareness, especially guidance tailored for children and elderly citizens, reduces risky interactions.
