Buying the best training tools for your extra large dog can make all the difference in whether or not your pooch is well-mannered or struggles with the basics. While muzzles are controversial to some, muzzle training your dog can be a great way to reduce their stress in situations that previously caused them to bite. It’s also worth noting that, while we’re suggesting a muzzle as a training tool for an extra large dog like a Bernese Mountain Dog or Irish Wolfhound, muzzles are not synonymous with size or breed. Dogs of any size or breed may need to be muzzle-trained. We like the Baskerville Ultra Muzzle, as it is comfortably dog-friendly and allows enough room for panting, drinking, or eating.
