Dog shedding is a real problem in my home. Up until last year, I had a dark-furred dog and a light-furred dog, and cream carpets. Now, I have three dark furred dogs, and cream carpets. For as many years as I can remember, I've experienced a seasonal shedding problem that, for alternate weeks, sees my home covered in light dog hairs and then dark dog hairs, now it's just dark which covers the carpets throughout.
