Dogs shed the most during two main seasonal periods: in spring (around March to May) and in fall (around September to November). This shedding coincides with changes in daylight length and temperature, signaling the dog to shed its winter coat in spring to prepare for warmer months, and shed its summer coat in fall to grow a thicker winter coat. The spring shedding is usually more intense because dogs lose their thick undercoat at this time. Some breeds, especially those with double coats like Huskies, German Shepherds, and Golden Retrievers, shed noticeably more during these periods. Indoor dogs might shed moderately throughout the year due to artificial lighting and temperature controls. Dogs with single coats tend to shed less and more consistently year- round. Shedding typically lasts for 6–8 weeks during these seasons.
