I can definitely tell the difference now that i've been dealing with this. i will never worry about Luka being too rough with Knox again haha
ooh Also, forgot to mention that her bad behavior is starting to rub off on Luka. Last night he was laying down next to me and knox came up to him. (these dogs literally step on eachother, roll on eachother, anything with no issue) and he started growling at him and showing his teeth. He got a stern NO from me and immediately stopped and was fine but i will not be tolerating bad behavior just because he saw Sera acting that way! sheesh!
