If you're seeing toe nail loss, onychomycosis (fungal claw infection), bacterial infection of the claws, and a condition called symmetrical lupoid onychodystrophy - which is thought to be immune-mediated - need to be considered. The fungal and bacterial infections should be important differential diagnoses because we're seeing these infections due to immune suppression secondary to Apoquel but also due to hypothyroidism and allergies as you've mentioned Buster suffers from, plus hyperadrenocorticism (Cushing's disease), autoimmune disorders, and cancers. Buster's vet will need to perform a cytology (microscopic exam of exudates from a claw or claw fold) and fungal culture of nail shavings in order to identify an infectious agent. If infection can be ruled out, autoimmune skin disease and onychodystrophy become the most important differential diagnoses. Please respond with further questions or concerns if you wish.
