sorry, not sure about cockers, but i suppose shedding is pretty same with goldens.
i comb my pup's fur every 2 days and i use a brush, i will first brush against the fur line and u will see fur sticking to the brush. after that, brush according to the fur line. though brushing won't prevent shedding, it does help since u r literally combing the hair off slowly instead of getting a fur covered couch when it is cocker's time for the ultimate shedding (esp from pup into adult)
Hi there.. I have 2 cockers on my own.. Cockers do shed moderately esp. when they are growing up - lossing the puppy fur. Use a "slicker brush" to brush them as this brush would take out the dead hair.. One of the latest product that would help is the "mars Coat King" but it's pretty expensive....
