My note to this- I am glad I do not live in Indiana. A "Beware of dog" sign- at my door???? WITH MY DOGS???? Also- with home owners insurance, if you have a 'beware of dog sign" on your property, number one its hard to get coverage as its considered a liability declaration etc, not to mention to the state if your dog did bite someone- you knew you had an aggressive dog- and would probably be put down. ( I would have to post a sign as I would have two of 4 intact dogs..)
Also- you can not microchip some large breed dogs until 8 months old as the skin is moving too much and the chip will move unable to be read. My vet didnt suggest doing Zubin in a chip until he was 9 months old for this same reason...
