Startup Idea: Bad Dog Alert System for Delivery Personnel

Startup idea to develop a crowdsourced map-based platform where users can tag houses with potentially aggressive dogs. This tool can be used by delivery personnel to avoid dangerous encounters. Reports of police incidents involving a hostile dog can also be tagged.

Delivery people need a bad dog alert system. Bad dog tracker. Whatever. I am sick of delivering to houses and having their damn dog nearly bite my head off. The neighbors know which houses have the mean dogs.

Can't we have a map where people can go and tag the houses or addresses of the houses that have signs like BEWARE OF DOG? or houses that have been involved with police calls regarding their dog?

Just recently the police were called to a house over a threatening dog and the dog attacked the officer. He had to shoot the dog in the head. Imagine what it is like when you only have a pizza box to defend yourself.

This would make my life so much easier. When I know there are hostile dogs at a place I can call ahead to make sure the animals have been leashed or contained. Otherwise I'm just walking into a trap!
