Premium Shampoo is a care item in Nintendogs + Cats. It is a shampoo in a blue bottle with a yellow cap and label on it. It can be bought for $6 at BARC once it is unlocked with 5,000 Owner Points. Like the normal shampoo, it can be used on both long and short-haired dogs and cats. It can clean a filthy dog or a cat faster than the ordinary shampoo.
For Obedience Trials the player can use this shampoo for its beauty when judges evaluate the performance and care of the dog.
3DS: "This enriched shampoo leaves fur soft, shiny and squeaky clean."
