Thanks for the helpful tips guys! I am on my way to work so don't have a ton of time to post but just wanted to let you all know that I am well researched in the area of Katya's breed, she is actually pictured in a book about C.O.'s and I am aware that they are bred to be more aggressive. For the poster who stated why would I get a dog like that, I didn't. My mom did, she works for the FBOP and needed a high caliber dog since she was in a field where her safetly was a concern. I will come back and address the rest of the posts later. Thanks!
