If a golden retriever wants a good coat color, the best food is dog food, because dog food has been prepared according to a certain nutritional ratio and can ensure most of the dog's nutrition. If you want a golden retriever with a smoother, smoother coat, If it is shiny, you can also feed additional seaweed powder or hair beauty powder, and add more lecithin-rich foods, but remember not to add salt. Too salty and too oily can cause serious problems with the dog's kidneys or skin.
