How much do German Shepherds shed?

German Shepherds are moderate to heavy shedders who shed their topcoats year-round but shed their undercoats twice a year during seasonal changes. During these seasons, which are commonly known as “blowing their coat,” there is a significant increase in the amount of hair they shed. But regular grooming, including brushing, can help manage the shedding to some extent by removing loose hair and preventing mats.
