From the Research

Canine lupoid onychodystrophy is an autoimmune condition affecting dogs' claws, requiring prompt veterinary care, and treatment typically involves a combination of approaches including oral cyclosporine (5-10mg/kg daily) or fish oil supplements, as they have been shown to be equally effective in treating the condition 1.

Treatment Approaches

  • Oral cyclosporine (5-10mg/kg daily) can be prescribed to reduce inflammation and modulate the immune system.
  • Fish oil supplements, rich in omega-3 fatty acids, can help reduce inflammation and promote healthy claw growth.
  • Affected claws should be kept clean and trimmed to prevent further trauma, and protective booties may help during walks.

Disease Management

  • This condition occurs when the dog's immune system mistakenly attacks the claw tissue, causing inflammation, pain, and eventual claw loss.
  • While treatment can control symptoms, this is typically a lifelong condition requiring ongoing management.
  • Regular follow-up appointments are essential to monitor response to therapy and adjust treatment as needed.

Response to Treatment

  • Most dogs show improvement within 2-3 months of starting treatment, though complete resolution may take 6-12 months.
  • The treatment outcome can be measured by the change in the number of healthy claws during treatment, as well as the long-term effect on the dog's quality of life 1.

Key Considerations

  • A diet rich in omega-3 fatty acids can help support the treatment of canine lupoid onychodystrophy.
  • The genetic basis of the disease is still being researched, with potential candidate genes identified on canine chromosomes 12 and 17 2.
  • A combination of treatments may be necessary to achieve the best outcome, and the treatment plan should be tailored to the individual dog's needs.
