I have a 7 year old rescue lurcher who I have owned years.

This answer was rated:

I have a 7 year old rescue lurcher who I have owned for 6 years. She has been spayed and is in good health. Recently her nails (which are regularly trimmed by a professional) have started to split so you can see the underneath fleshy part. Her toes also look slightly twisted. The lady that trims her feet is sufficiently concerned and suggested I contact a vet.
The groomer is concerned that Honey suffers from symmetrical lupoid onychodystrophy (idiopathic onychomadesis) which is suspected to be immune-mediated and eventually causes claw loss (onychomadesis). It's uncommon with the highest incidence reported in young adult to middle-aged dogs. Usually, an acute onset of nail loss occurs. Initially one to two claws are lost, but over the course of a few weeks to several months, all claws slough. Replacement claws are misshapen, soft or brittle, discolored, and friable and usually slough again. Differentials include fungal and bacterial claw infection, autoimmune skin disorders, drug eruption, and vasculitis and so contacting Honey's vet would be prudent in an attempt to clarify which of these disorders is causing the split and twisted toes/nails. Diagnosis of symmetrical lupoid onychodystrophy is done by ruling out those other differentials, clinical symptoms and typical history. Biopsy isn't recommended in most cases. Please respond with further questions or concerns if you wish.
