Lower prey availability for wild carnivores like tigers and leopards2. These dogs may also be spreading rabies and other diseases to wild animals3. Mudumalai, also has large populations of the endangered wild dog or dhole.4. They eat infected carcasses hunted by domestic dogs=spread of disease.5. Training village dogs to procure wild meat is a criminal offence under the</p><p>category of poaching.
