Evaluation of methods for short-term marking of domestic dogs for rabies control

The livestock marker spray can effectively be used to mark dogs that are physically restrained, for example during vaccination campaigns. Resight surveys should be conducted within a short a time as possible after marking; however, our results suggest that loss of marks will not have a significant impact if surveys are conducted within 5-7 days after marking with the spray. Results that depend on observers' abilities to distinguish between the three colours which we evaluated may not be reliable.
