I just noticed Onguard has a new pitbull mini called the 5013TC .

It has a thinner cover so i guess the size is more like the bulldog. I like how it has a yellow strip on it, so from a casual look it appears like the Krypto New York.
Looks like locks are starting to copy the animal world, mimicking others to gain an advantage!
