Shedding occurs all year round in German Shepherds. Spring and summer are the most common times for shedding. German Shepherds replace their coats with thicker ones that can protect them against cold during the long winter days. Many of them will shed less frequently between 4 and 6 months old, then again at year intervals and usually in waves. German Shepherds are prone to shedding, especially when they are introduced to new environments or go through a transitional period. So, don't fret if you find fur everywhere in your house. Shedding is a positive sign that your dog is healthy, in good body condition, and has enough energy to deal with the extra hair around them.
