Squeaky Wheel
This one ain't that hard to figure out. I'm surprised one of you didn't come up with the answer. Fido has an owner. When you run him over the owner sues us. Bambi is a wild animal with no owner. No owner no claim.
In an area with a leash law, the owner may sue but the law is on the side of the company. When said company disagrees with the law and claims that the driver coulda/shoulda avoided it they have then admitted liability and opened themselves to a claim.
