This is an A-M-A-Z-I-N-G product. I've also used it on my Samoyed and the brush just glides through his coat. I have a Gypsy Vanner with double Mane and a tail that is so thick. No Nots makes grooming an absolute breeze. LOVE, LOVE, LOVE it!!!
I use this NRG No-Nots on my horse and ponies. It makes removing knots, tangles and ropes in manes and tails easy. It also helps to stop hair being pulled out with the brush. Depending in the weather, each application seems to last a couple of weeks too with the manes and tails being generally easier to brush.
NRG works well in removing knots from my long haired Shepherd
