I've been giving it to my two show types for about 3 years now. They have full coats - not clipped. Took about 6 weeks to see improvement so don't expect immediate changes. I find it makes their coats more silky and manageable as well as glossy/shiny. Some people use salmon oil which may/not have a similar effect. I won't be changing product, though Don't know which ingredient does what but yumega is flax oil with starflower oil.
