A lot factors into the shedding..food for example. I like the furminator bc it will open the pores the help release the undercoat but the key is the conditioner which closes the pores back up and the brushing. Petsmart uses a velocity dryer to force out that undercoat with the furminator shampoo and conditioner and then brushing. Also frequency helps...its not going to stop bc its a natural part of life but it can have a significant impact on the amount
There are many varities of shampoo that work great for shedding. Are you wqnting to promote or prohibit? I find that if you are specific with your question, you are more likely to get an accurate answer.
