I use it on GUCCI weekly as well, and I love it.. it has a great scent, leaves the hair shiny and soft, & it stays fluffy and smooth too.
We use the Tears for Fears (blue bottle) It works great! Try it out, if you use Tigi Products on yourself you will love them for your dog, same great scents and they seem to have the same effect on the hair...

The company didn't Skimp on packagin either it comes in a wonderful generously sized bottle that should last months.
I should be a Spokesperson for them lol
