A dog's fur should be shiny and silky relative to their breed. Greasiness, odor, and dull hair is all due to kibble and cooked food diets. As a puppy you may not notice it so much, but as they age and their body isn't able to make up for the shity diet, the drag will become apparent. Fun fact, my dogs take on the smell of a broth made from whatever animal they are eating at the time. My favorite is when they eat a whole lot of pasture-raised chicken or turkey. It smells like chicken soup or Thanksgiving haha
