We got our shampoo the other day and this morning I used it for the first time on my 16 week old puppy. Well, he smells wonderful and his coat is very soft , but there was no sheen at all no matter how long I brushed. After about half hour I gave up because the poor baby was just getting annoyed with me. I think the sheen aspect doesn't work on puppy coats. I'll keep it and use it when he is older and see if I get the same results everyone else has testified to.
