Instructions
Buy a brush called an undercoat rake. The tines on this brush remove large tufts of hair. Buy a rake that has teeth long enough to penetrate through to the skin. You'd need longer tines for a dog with a longer coat, but using a rake that's too big on shorter haired breeds can hurt them.
Check out a special rake called the FURminator. This rake has very fine teeth that push through the topcoat to remove dead hairs from the undercoat. It won't damage the guard hairs that give your dog his great looks.
Bathe your dog every few days. You can get a special blower to dry him off (and help blow out some of the fur) or use a hair dryer.
Keep your dog off the couch. This is especially important if your couch is made of a fabric that collects dog hair easily.
Vacuum every day or every other day. Tufts of hair will end up all over your house if you don't brush your dog often enough while he's blowing coat. If you're good about brushing him outside, you may not need to vacuum as often.
How to Handle a Dog Blowing Coat
There are a few types of dogs who seasonally "blow their coat." These dogs don't shed throughout the year. Instead, their undercoats shed every so often, which can create a mess all over your house. The shedding period can last a few weeks and usually occurs in the spring and fall.
