I have two German Shepherd's. MY male Blaze is 13 years old, and my female Cyndee is 5 years old. Both really shed quite a bit despite my brushing them at least once a week. Does anyone have any solutions as to what I can use on their coats to keep the fur from flying.

I live in Michigan, not sure if that bit of information is beneficial in solving this .

Thank you
