More shedding occurs in spring and fall to let thicker/lighter coats suit the changing seasons.
Seasonal Growth Cycles
Heavy shedding breeds like Huskies and German Shepherds blow coat more. Non-shedding breeds shed less.
Very young and senior dogs tend to shed more due to hormonal changes.
The UV radiation of summer sun causes dogs’ undercoats to shed out.
Dogs shed to cool off in summer and insulate in winter. Excess heat also increases shedding.
Shedding removes damaged or dead hair so healthier fur can grow in.
Removing Dead Hair
The growth cycle replenishes skin and coat oils through shedding old hair.
