What is the difference in a regular pitbull and razor edge pitbull?

There is no such thing as a "razor edge Pitbull". This is a misleading term that likely refers to a Pitbull with a cropped ear, which is a surgical procedure that removes a portion of the ear.

It's important to understand:

* "Razor edge" is not a recognized breed or type. Pitbulls are a type of dog, and the term "razor edge" is simply a description of their appearance.

* Cropping ears is a cosmetic procedure with no health benefits and is often done for aesthetic reasons. It can be painful and is considered unethical by many animal welfare organizations.

* All Pitbulls are individuals. Their temperament is influenced by genetics, environment, and training, not by their appearance.

It's essential to focus on the character and well-being of individual dogs, not on arbitrary labels or cosmetic changes.
