In the last 4 years there have been 40 dog bite incidents in which Ameren Illinois employees were bit. 

Brian Bretsch, spokesperson for Ameren Illinois, says that Ameren employees go through dog bite prevention training but it also takes some vigilance on the part of Ameren customers to keep everyone safe.

The dog encounter training is called Bulli Ray and is intended to prevent dog bites with neither the employee or the dog being harmed. Bretsch says that Ameren doesn't blame dog owners or the dogs who are simply guarding their homes. That said, if an employee is bit, it does require authorities to be called. Thus, it's important for Ameren employees and Ameren customers to take care when it comes to dogs.
