It’s no secret the German Shepherds second name is German Shedder.
To help maintain the enormous amount of dog hair in my house I use the SleekEZ dog brush or the King Komb brush. Both brushes are about 20 dollars but is well worth it. The King Komb is in my opinion a better brush because it has more blades with different patterns to better get into that lower under hair (winter coat) type hair. In 10 minutes or so I can brush off a whole second dog. After brushing with this brush (and vacuuming the house) I can definitely notice a difference. The beginning of spring and summer I brush about everyday to every other day. Later in the year I brush about every 3 days or as I see is needed.
This brush also works on short hair dogs, cats, horses, cows, and like haired animals.
