Most dogs shed for about six months of the year. The most popular shedding seasons are spring and fall.

During fall, this itching might occur after a dog gets wet. If he’s been outside playing, he’ll probably get waterlogged. When he takes off his muddy clothes, the loose dirt will stick to his hair. As soon as the dog scratches himself, his hairs shed off.
