Seasonal flank alopecia

From Dog
Seaonsal alopecia in an Airedale Terrier[1]

Seasonal flank alopecia is a relatively benign hormone-induced hair loss reported in the Affenpinscher, Airedale Terrier and Boxer breeds[2].

This condition, which primarily affects middle-aged neutered female dogs during winter months, is characterized by a symmetrical alopecia over the flanks, dorsum and tail regions[3]. Entire females and neutered and entire males can also be affected.

Blood tests and skin biopsies should be performed to exclude other causes of alopecia such as hypothyroidism and demodicosis.

No treatment is usually required for this condition as it normally resolves spontaneously during warmer months[4].
