Irondequoit police have put out the bodycam footage of a Friday dog attack.
They say the dog bit a 1-year-old on Strathmore Circle.
It then attacked an animal control officer at the scene, after it slipped out of its leash while its owner was bringing it to the officer's van.
An officer opened fire, killing the dog.
Investigators say the dog had no vaccinations or license, and is being examined for rabies.
