A dry nose in dogs is a common concern among pet parents. While it's not always a cause for alarm, there are several things that can cause a dry nose including hyperkeratosis, autoimmune diseases, infections, and even dry eye. Treatment depends on the underlying cause but there are topical preparations that dog owners can use to help provide comfort. In this article, we will explore the various causes of a dry nose in dogs and discuss treatment options.

Hyperkeratosis

Hyperkeratosis is a common cause of a dry nose in dogs. It is a condition where the nose becomes dry and cracked due to an overproduction of keratin. Most cases of hyperkeratosis occur in older dogs and often affect the foot pads as well. Labrador retrievers can develop hereditary nasal hyperkeratosis at a young age.

In most cases, no treatment is required. Topical products containing salicylic acid can be used along with vitamin E or Aloe cream. If you notice a discharge from the area or if there is an odor, it may be a sign of infection and you should contact your veterinarian for treatment options.

Hypothyroidism

Dogs with hypothyroidism can also have a dry nose. The vast majority of dogs with hypothyroidism will have dermatological symptoms and a dry nose is one of those symptoms. Other common symptoms of hypothyroidism you may notice are hair loss or thinning to the haircoat, weight gain, and lethargy.

If you notice any of these symptoms in addition to a dry nose, it's important to contact your veterinarian for testing. Hypothyroidism is a common condition that is easily treatable with thyroid medication.

Autoimmune diseases

There are different autoimmune diseases that can cause a dry nose in dogs. Pemphigus and discoid lupus erythematosis are autoimmune diseases that affect the skin and mucous membranes. It causes significant blisters and crusting on the nose as well as around the eyes, ears, and sometimes the feet.

If you notice any lesions on the nose or other areas of the body, it's important to contact your veterinarian for treatment options. To suppress the immune system, corticosteroids are often used in the treatment of autoimmune diseases. Autoimmune diseases can be difficult to manage but with proper treatment, most dogs can live a normal life.

Dry eye (Keratoconjunctivitis Sicca - KCS)

Dry eye or keratoconjunctivitis sicca (KCS) is another common cause of a dry nose in dogs. It is an autoimmune disease that affects the tear glands. The tear glands produce tears that keep the surface of the eye moist. When the tear glands are damaged, it can lead to dryness and irritation of the eyes.

Deficiency in tear production can lead to a dry nose in dogs, as the nasolacrimal duct brings tears from the eyes to the back of the nose and sinuses. If only one eye is affected, you may notice that only one side of the nose is affected and dry.

KCS is a condition that can be treated and managed. Your veterinarian will prescribe medication to increase tear production that will not only help the eye(s) but also the dryness of the nose.

Mucocutaneous pyoderma

Mucocutaneous pyoderma is a bacterial infection that affects the skin and mucous membranes. It can cause crusting, redness, and ulcerations on the nose as well as around the eyes, ears, and mouth.

If you notice any lesions on the nose or other areas of the body, it's important to contact your veterinarian for treatment options. Mucocutaneous pyoderma can be treated with antibiotics and topical therapy but treatment is usually required for 4-6 weeks.
