# Why Dog Culling Does Not Work

> Dog culling does not work because removed dogs are quickly replaced by breeding and migration, while rabies control depends on vaccination coverage, not killing.

## The Vacuum Effect
When dogs are removed from an area, food sources and shelter remain. Surviving dogs breed, and unvaccinated dogs move in from neighbouring areas. This replacement effect means population numbers can rebound quickly after culling.

## Why Culling Fails Rabies Control
Rabies is controlled by vaccination coverage. Killing dogs without vaccinating the population does not create herd immunity and may make outreach harder by damaging community trust. Stable vaccinated dogs protect territories and help block transmission.

## What Works Instead
Catch-Neuter-Vaccinate-Return combines humane catching, surgery, rabies vaccination, identification and return to territory. When delivered consistently at scale, CNVR reduces breeding, stabilises populations and supports public health.

## The Vacuum Effect Explained
Removing visible dogs creates empty territory. New unvaccinated dogs move in within weeks. Surviving dogs breed faster with reduced competition. Rabies coverage never reaches the roughly 70% threshold WHO cites for transmission interruption — so culling fails both welfare and public-health goals.

## CNVR as the Evidence-Based Alternative
Catch-Neuter-Vaccinate-Return stabilises vaccinated populations in place. Breeding slows, bite incidents fall and communities build trust with humane field teams. WARN funds CNVR through partners in Pakistan, the Philippines, India and Nepal across the 17-country network.

## Why UK Donors Choose WARN — Transparent Partner Grants
WARN is a registered UK Community Interest Company (Company no. 17298990) and is not a charity, so it cannot claim Gift Aid. The donation case is transparent partner-led welfare where support reaches practical field needs. WARN states upfront that gifts fund WARN's 17-country partner network across South Asia, Southeast Asia, East Africa, Southern Africa and South America programmes through vetted local partners — not WARN-run sanctuaries. Every gift is receipted; give one-off at /donate or monthly at /donate/monthly.

## What WARN funds
- CNVR clinic days in high-need street dog communities.
- Rabies vaccines, surgical consumables and mobile veterinary equipment.
- Training for humane catching and community education.
- Emergency shelter for injured or non-releasable dogs.
- Evidence-based CNVR programmes replacing culling in partner cities.

## FAQ
### Does killing street dogs reduce rabies?
No. Rabies control depends on vaccinating enough dogs to interrupt transmission. Culling without vaccination does not create herd immunity.

### What is the vacuum effect?
The vacuum effect is the rebound that happens when removed dogs are replaced by new animals or increased breeding among survivors.

### What is the humane alternative to dog culling?
The humane alternative is CNVR: Catch-Neuter-Vaccinate-Return, delivered at sufficient scale with community education.

### Why do cities still cull dogs if it fails?
Culling is politically visible and fast — but evidence from WHO, WOAH and peer-reviewed studies shows it does not control populations or rabies long term.

### What vaccination coverage stops rabies?
WHO guidance targets roughly 70% of the free-roaming dog population vaccinated — achievable only with sustained CNVR, not one-off culls.

### Can UK donors fund CNVR instead of culling?
Yes — donate to /appeals/karachi-dogs or /rescue/help-street-dogs-abroad. Gifts fund humane alternatives through local partners.

### How long does CNVR take to work?
Typically three to five years of repeated rounds to stabilise populations and reach vaccination thresholds — another reason monthly giving matters.

### Is WARN a registered charity?
World Animal Rescue Network (WARN) is World Animal Rescue Network CIC (Company number 17298990), a registered UK Community Interest Company — not a registered charity. See /about/registration-status for full legal identity.
