4. Allergies can also cause dry nose among Shih Tzu dogs
You need to check your home for anything that could trigger allergies in your Shih Tzu. Plastic bowls can be a culprit, so you may want to consider switching to stainless steel, which also don't harbor as much bacteria as plastic. You can also evaluate your pet's food, treats, toys, and even bedding to see if any of these cause alleries that have lead to dry nose.
