Hi and welcome to YT! Congrats on your new baby. I don't know about that food as we don't have that in SA, but I'm sure some one will come along and assist.
I do, however, use coconut oil on my boy and I think he has a great coat. Also, remember that their coats change and thicken as they grow older and out off their puppy coat. So for now, while she's still a baby, I think feeding a good quality food is key, no grooming dry hair and not bathing her too often, and a great shampoo and conditioner!
Good luck, and cant wait to see pics
