What did I do?

my bulldog has to wear a muzzle at times... not because of any laws... but because she has a vendetta with my coydog.... she's so used to Lady picking a fight with her when she goes out for walks that she has actually started to expect the fights.... not good, not good at all.... the bulldog isnt dog aggressive at all, she gets along fine with our other two dogs, but she litterally has an almost human hatred for Lady... i decided the only way to help Lady's chances of survival should the bulldog get loose is to muzzle her....
I dont like it at all, i especially dont like it because people see a bulldog with a muzzle and their thoughts automaticly turn to "of COURSE It's DANGEROUS!!"
Poor Kaydee hates the muzzle too.... she really doesnt deserve to wear it, but I havent yet figured out a way to prevent Lady from instigating fights with her. Lady is almost twelve years old, she's a bit senile, and thinks she's still alpha and tries to dominate the bulldog..... i'm just glad i live further out in the country where i dont have to worry about people nextdoor calling the cops and accusing me of baiting a bulldog with a weaker dog. Kaydee used to be beautiful but Lady has her face scarred up so she looks like a fighting dog.... i absolutely hate it...
