Many dogs, including the Kuvasz and their cousins the Great Pyrenees, the Maremma, the Abruzzese Mastiff, and the Pyrenean Mastiff. can all have some level of nose dryness. This dryness can range from a bit of dullness or dryness to the more extreme condition, Nasal Hyperkeratosis, in which the entire nose is covered with layers of crusty, scab-like tissue - see examples in the video.
The GOOD NEWS is Nose Butter® moisturizes all levels of dog nose dryness from a wee bit dry to extremely dry Nasal Hyperkeratosis. This dryness of your dog's nose is a condition, so it's usually not curable, but Nose Butter can keep it under control by moisturizing the dry nose and keep it healthy...with regular usage.
