(fair warning this might be a generalization and varies based on location)

unless there is a reason for it, muzzling a dog just for being a specific breed is not a good precedent(and muzzling based on this alone is animal abuse), and while some places enforce it( a lot of actually) it tend to not be mandatory or at worst fine worthy, under the knowledge that the owner is legally liable for anything that happens.

wanna not have to muzzle dogs at all? Train them properly, a pitbull can be incredibly tame...if the owner isnt encouraging them to be agressive or is actively abusing them, but at the end of the day a dog is gonna go dog if provoked hard enough(and its not gonna be the animal's fault).

you should honestly be more scared of the smaller breeds of dogs since on their cases its been normalized to encourage shtty behaviour pattenrs(that make them incredibly anxious and skittish) that makes them a bigger danger of attack.
