Welcome to JustAnswer! I am a licensed veterinarian and would be glad to help!
There are many dogs that do get a dry, and even cracked nose. A product that may help is Kerasolv - this is a common product used for these hyperkeratotic conditions - the active ingredient in this is salicylic acid.There are times when an infection (bacteria, mites, etc) or systemic disease can lead to the dry nasal or cracking condition, but that medication (Kerasolv) discussed above (example click here) may be of use.The link above will direct you to an example - you may want to talk to your veterinarian about using this - it helps quite a bit in many patients! Antibiotics or other testing can also be considered at that time.I hope this information helps!
