Crusty nose getting you down?

French Bulldogs are highly predisposed to nasal hyperkeratosis, a condition characterised by the overproduction and accumulation of keratin on the nose, leading to dryness, crusting, and thickened tissue. This occurs because brachycephalic breeds often have reduced natural licking ability due to their shortened muzzles, preventing them from keeping their nasal surface moist. While mild cases are primarily cosmetic, more advanced hyperkeratosis can cause discomfort, fissures, and secondary infection. A structured care plan combining hydration, topical keratolytic therapy, and environmental management is key to maintaining a healthy nose.

​

Regular moisturisation is the cornerstone of treatment and prevention. Daily or twice-daily application of a pet-safe, non-toxic nose balm helps soften and rehydrate the hardened tissue. Veterinary and specialist products such as Natural Dog Company Snout Soother, Vet’s Best Moisture Mist for Dogs, Paw Soother (by The Natural Dog Company), or Petroleum Jelly USP (applied in very thin layers) can be effective. These formulations typically contain shea butter, coconut oil, beeswax, and vitamin E, which help restore flexibility and protect against environmental irritants. Products containing essential oils, camphor, or menthol should be strictly avoided, as they may cause irritation or toxicity.

​

For dogs with severe or persistent hyperkeratosis, keratolytic agents—which help break down and loosen excess keratin—may be beneficial under veterinary supervision. Mild cases can be treated with creams containing urea (2–5%) or lactic acid, such as Epi-Soothe Cream or Kera-Mend Urea Gel, used sparingly once daily. These products help smooth the surface and prevent painful cracking when used consistently.

Environmental control is also important. Central heating and air conditioning can cause low humidity, which worsens nasal dryness. Using a humidifier in the home, especially in the sleeping area, can help maintain adequate ambient moisture. Ensuring adequate hydration through fresh water access and a balanced diet rich in omega-3 fatty acids (such as Welactin or Grizzly Omega Health) can also improve skin and nasal health from within.

​

Owners should avoid picking or trimming crusted tissue, as this can lead to bleeding and infection. Instead, gentle softening with a warm, damp cloth before applying moisturiser can help lift dead keratin naturally. In cases where fissures or infection are present, veterinary evaluation is required, as topical antibiotics or antiseptics such as Fuciderm Gel or Isaderm may be needed.

​

Monitoring for secondary complications is important, as chronic hyperkeratosis can lead to discomfort, nasal bleeding, or bacterial colonisation. Dogs that suddenly develop severe hyperkeratosis should be assessed for underlying systemic disease, such as hypothyroidism, autoimmune conditions, or idiopathic keratinisation disorders.

​

With consistent moisturisation, keratolytic therapy where appropriate, and supportive environmental measures, most cases of nasal hyperkeratosis in French Bulldogs can be effectively managed. Regular maintenance is typically lifelong, but when performed correctly, it preserves the dog’s comfort, prevents cracking, and restores the soft, smooth texture of a healthy nose.
