Get an Oster undercoat rake. I like it waaaay better than the Furminator thing.
I prefer hand carding (google carding grooming) using a dull Wahl clipper blade, but it takes time.
This is what I'm working with:
You should look at what you're feeding. Allergies and a bad diet can cause unnecessary year-round shedding.
Don't get me wrong my dog sheds some year-round and we have all hardwood too, BUT most of the year I can get by vacuuming once or twice a week which I don't think is so bad that I would screaming for help.
Twice a year, approximately 4 months after her heat cycle she blows her coat -- during that time I can brush every day and vacuum every day and still get behind!!!!
You're supposed to have a bit of a break when it's not "shedding season" (coat blow) and if you aren't getting a break from it then I would bet my next paycheck that the issue is nutritional.
Besides oils you can add vitamins to the diet. Check the vitamin aisle of
Petco or
Petsmart, or even
WalMart. I get one called Brewer's Yeast and Garlic, and also one called Healthy Coat. I have noticed that they help with re-growing hair after shaving, but I don't know what they do for shedding.
