I was given Gravy when he was around 1.5 years old. At the time he had really soft golden fur, everyone that touched him says he's got such soft puppy fur. As he got older, I noticed that his fur had lost that 'puppy' softness, and had just accepted that that's how it goes. Then my friend introduced me to THK, I tried it because Gravy is important to me and I want to make sure he eats healthy food, as I would for my family. Little did I anticipate, the upside-side-effect is that his fur turned puppy soft again! AND in his coat of fur there are some hairs of pearlescent furs! It is just beautiful and he's getting complements all time again on his fur and how soft it is. I like THK for my dog not only for the health of his fur, but for his overall health.
