Why is it difficult to muzzle brachycephalic dogs?

Muzzling brachycephalic dogs can be challenging due to their short snouts and unique facial structure, which can make it hard for traditional muzzles to fit properly. These breeds often have breathing difficulties, so a muzzle that restricts their mouth too much can exacerbate those issues. Additionally, their anatomy may lead to discomfort or stress when wearing a muzzle, making it crucial to choose a design that accommodates their needs while ensuring safety.
