There are many types of environmental irritants that surround us and our pets each and every day including fleas, pollen and even the dust in our homes. For some dogs these irritants can cause a skin condition that may lead to scratching, sometimes excessively. This is unpleasant for your dog and can also be difficult for everyone else in the family. The good news is most dogs with these skin conditions can benefit simply from the right food.
