Yes, huskies shed a lot. Huskies have a double coat of hair: a top coat of stiff hairs for protection and a softer undercoat for insulation. With a double coat, you can expect your dog to shed a lot.
Huskies will shed their softer undercoat once or twice a year during the spring and fall. In the spring they start to shed their thick winter coat to be cooler in the summer, and then shed their lighter summer coat for a thicker winter coat with more insulation for the cold winter months.
In addition to the two shedding seasons, husky puppies will shed all of their puppy fur when they are around 10 to 14 months old.
Health problems like allergies or skin problems also cause huskies to shed a lot.
