Jake has a very thick undercoat, so he needs a good brushing every week. Some times I slack and he doesn't get brushed as often anymore. All the hair above came from 30 minutes of brushing. I know I can get that much more off of him in another week too! Good thing I love grooming the dogs.

The Furminator is an excellent deShedding tool to help get all that dead undercoat out. Many people have had great success using this for their German Shepherds. However, I own one, and it does not do the job for Jake. Always worth a try though.
I prefer the Undercoat Rake. All of the hair I took off Jake came from using this tool. Very easy and simple to use. Brushing Jake every two weeks keeps his shedding to a minimum, but, he is a German Shepherd, so he will always shed. Having five dogs in the house is a good reason to own a very good vacuum.
