Why is my dog shedding so much in the fall?
Keeping this in consideration, why is my dog shedding so much in the winter?
Shedding Season Most dogs are double-coated; they have undercoats and top coats. Seasonal shedding occurs as a result of temperature change. This process is sometimes called "blowing coat." When the weather warms, dogs shed their old winter undercoats to make way for a lighter summer coat.
Accordingly, why is my dog shedding so much all of a sudden?
What seems like excessive shedding can be normal for some dogs, but it can also be the result of stress, poor nutrition or a medical problem. Your veterinarian can best determine if your dog's hair loss is part of the normal shedding process or is a symptom of an underlying disorder.
Skin allergies and parasites may trigger shedding, as will a poor diet. It matters if your dog is an indoor or outdoor dog, too. If your dog is an outdoor dog, his coat is likely to follow the seasons to keep him insulated from the winter cold or cooler in the summer heat.
