Yes, sheepdogs shed a lot of hair, particularly during shedding season. Sheepdogs have a thick and dense double coat that consists of a soft undercoat and a longer, coarser topcoat. This coat helps protect them from the elements while they're working in the fields, but it also means that they shed a lot of hair throughout the year. During the shedding season, which usually occurs in the spring and fall, sheepdogs will lose even more hair as they shed their winter and summer coats. This shedding can be quite heavy and may require more frequent brushing and grooming to keep their coat under control. Regular grooming is essential for sheepdogs to help prevent matting and tangles in their coat and to keep their skin healthy. Brushing their coat at least once a week can help remove loose hair and distribute natural oils throughout their coat, which can keep them shiny and healthy. Additionally, trimming their hair and bathing them as needed can help keep their coat looking and feeling clean and healthy.
