Dogs suffer from a wide variety of allergies, and a dry nose can be a sign that a pooch is suffering from any of the numerous canine food, environmental or skin allergies.
Dogs’ noses tend to dry up as they age, and a drier-than-normal nose may be an indication that your dear fido is advancing in age.
Brachycephalic dog breeds, like the Bulldog, with short snouts and pushed-in faces typically find it difficult to reach and lick their noses with their tongues. And this often leaves such pooch’s noses dry.
Certain pooches have fairly sensitive skin. And if exposed to the sun for a considerable period, especially when playing outside, there is every chance that the dog’s nose will dry out due to sunburn, and in some cases, the nose may crack.
Sleeping A Lot
Additionally, a dry nose in a dog may mean nothing more than the fact that the pooch has been sleeping too much, and is unable to groom its nose by licking frequently.
Medical Reasons For Dry Noses In Dogs
Most of the reasons listed above for dry noses in dogs can be considered to be minor. But at the same time, a dry nose can also be a sign that a pooch is suffering from an underlying medical condition.
That said, some of the medical conditions that typically cause a dog’s nose to dry up include:
Nasal hyperkeratosis is a skin condition that causes excessive production of keratin by a pooch’s body, which in turn results in the hardening of nasal mucous, and subsequent nose dryness and crustiness.
Canine nasal hyperkeratosis is typically caused by a hereditary disorder or due to an infectious disease, but causes also include reaction to certain medication.
A dog’s dry nose can also be an indicator of a serious medical condition such as dehydration, which occurs when the pooch’s body lacks adequate water.
Dogs suffering from dehydration, apart from having dry noses, also exhibit weakness, and their skin typically fails to quickly snap back into position when pulled and released.
Dogs’ eyes and noses are connected in a way that excess moisture from the eyes drains into, and keeps the nasal passages moisturized. Consequently, if a dog is suffering from a dry eye, the nasal passage will fail to receive enough moisture, thereby resulting in a dry nose.
Apart from nasal hyperkeratosis, dryness of a dog’s nose may suggest that a pooch is suffering from an autoimmune disease, with the most typical cases being Lupus and Pemphigus.
These autoimmune diseases are caused by a variety of factors including genetics, certain medication, disease-carrying ticks, among others. And they affect a pooch’s skin by causing it to dry up, and develop cracks which can be painful for the dog.
