Joe Jonas And Sophie Turner's Dog Killed In Freak Accident

This has to be super sad -- Joe Jonas and Sophie Turner's dog Waldo was killed by a car in NYC accidentally after it got loose from their dog walker and ran into a busy street. Joe and Sophie were so messed up over it that they went to their therapist and didn't report it to police for two days.

I've never had a dog, so I've never had a dog that got hit by a car, but -- why would you report your dog getting hit by a car accidentally to police, again?
