There is no breed, age, or sex predilection.1 Four common reaction patterns that are similar to feline allergic dermatitis and CAFR are seen (FIGURES 4 and 5): miliary dermatitis (papules with crusting), symmetrical alopecia (
caudal dorsum and flank area most common), head and neck excoriations, and eosinophilic granuloma complex (indolent lip ulcers, eosinophilic plaques, and eosinophilic granulomas) 2.
Nonpruritic hair thinning or alopecia (usually bilaterally symmetric) that may involve the ventral and lateral trunk, the
caudal surfaces of the thighs,
dorsum of the tail, ventral neck, and the
dorsum of the nose is seen in about two - thirds of dogs with hypothyroidism.
