Muzzles work well for most dogs too. We had some nipping issues training a dog and we’d do the “yelp” and pull away looking hurt thing, but if it wasn’t good enough then we’d follow up by muzzling him and ignoring him while he was pathetically trying to get the muzzle off or headbutting us trying to get it off. Once he calmed down and was behaving well we’d go to him, praise him “good calm” and take the muzzle off and give him some positive attention.
He’s a German Shepherd, so very trainable, and he learned quick. YMMV of course.
Enjoy,
