What does bite ratio measure in a K9 assessment?

• A. Proportion of dogs that bite during a session
• B. Number of suspects that get bit vs. the number of suspects that don't get bit
• C. Total bites recorded in an event
• D. Rate of bite incidents per hour of testing

Answer: (B)

The main idea is how often a dog bites relative to how many times it is exposed as a suspect. Bite ratio looks at the number of suspects that get bitten compared with the number that do not, giving a sense of the dog’s bite propensity across exposures. This is different from counting total bites, measuring bites per hour, or just noting whether a bite occurred at all in a session. So the best description is the comparison between suspects bitten and suspects not bitten, which reflects how often the dog bites when faced with exposure.
