I don't use the smaller one. For feet I use a small slicker brush and for ears/head I use a wooden bristle brush & a greyhound comb. These were all suggested to me by Jeannie and they work great! I highly recommend her video as well if you plan on grooming your newf yourself. Very clear instructions and easy to follow. I only use the Mars Coat King during heavy shedding periods (like twice a year...spring and fall) and I really only use it on the shoulders, back, sides and front chest. Otherwise my dog would be bald!
