We received three unique muzzles for testing that we wanted to introduce in a separate article before writing their reviews. Muzzle training is crucial to ensure the dog will be comfortable wearing the muzzle in the future. Many think that putting a muzzle on a dog without introducing it properly will magically solve their problems, but it is more complex than that. Muzzle training can take from a few days to a few weeks, and it ends when the dog willingly puts their face in the muzzle (or doesn’t mind you putting it on) and doesn’t try to remove it.
