Brittle Nails and Nail Bed Infections
Brittle nails and recurring nail bed infections in dogs are more than just a cosmetic issue—they can indicate underlying health imbalances. Identifying the root cause is essential for prevention and long-term healing. Traditional Chinese Veterinary Medicine (TCVM) provides insight into how these issues relate to organ health, while a holistic approach—including diet, herbs, and essential oils—can help restore nail strength and prevent infections.
1. Trauma and Injury
Repeated trauma from rough play, running on hard surfaces, or improper nail trimming can cause cracks and splinters, allowing bacteria and fungi to enter.
Exposure of the quick increases the risk of infection and inflammation.
2. Fungal or Bacterial Infections
Bacterial infections (paronychia) can lead to redness, swelling, and pus formation around the nail bed.
Fungal infections (onychomycosis) may cause thickened, brittle, and discolored nails.
3. Autoimmune Disorders
Symmetrical Lupoid Onychodystrophy (SLO): An immune-mediated condition causing brittle, cracked nails that frequently fall off.
Pemphigus or Vasculitis: Autoimmune diseases that result in nail deformities and chronic infections.
4. Nutritional Deficiencies
Biotin (B7) and Zinc deficiencies contribute to weak, brittle nails prone to breaking.
Omega-3 fatty acid imbalance leads to poor nail and skin health.
5. Hormonal or Endocrine Disorders
Hypothyroidism: Causes brittle nails, recurrent skin infections, and a poor coat.
Cushing’s Disease: Weakens the skin and nails, making infections more likely.
6. Allergies (Food or Environmental)
Chronic inflammation from allergies can cause excessive licking and chewing, leading to secondary infections in the nail beds.
7. Parasites or Mites (Demodex or Scabies)
Can trigger inflammation, itching, and secondary bacterial infections in the nails and surrounding skin.
8. Cancer or Tumors (Rare but Possible)
Squamous Cell Carcinoma may affect the nail bed, leading to chronic infections and nail loss.
