Following two recent dog bite incidents in Polk County, Iowa that resulted in serious injuries and one fatality, animal experts are stressing the need for pet owners to better understand their dogs' personalities and communication cues. Cassandra Johnson, an animal behavior supervisor, advises owners to seek professional guidance if needed and pay close attention to canine body language to avoid dangerous situations. Investigators are examining whether negligence played a role in the attacks, while some residents remain confident their own friendly dogs pose no risk.
