If you reside in a very dry environment or keep the heating high all the time in a cold climate, the air in your home could be drying out your Frenchies' skin. Dry skin is usually less supple, susceptible to flaking, and itchy, ensuring that your French is always scratching. This scratching can also make established skin problems worsen. How to treat Low Humidity Dandruff When it comes to your French Bulldogs' dry skin, a humidifier is one of the most effective things you can do. It would be wise to consider getting one if your French Bulldog suffers from dandruff, especially in the winter. It may also be beneficial depending on where you live. Having dry and itchy skin means your pet will not be able to relax and sleep peacefully during the night. An additional benefit of having a humidifier is soothing your Frenchie's skin. It can also help with dry nose and breathing issues.
