Rich in nutrients
"Nutrient-rich" in an ingredient for your dog's diet means that this ingredient contains a high concentration of important nutrients. These nutrients are essential for your dog's health and well-being. They usually include vitamins, minerals, essential fatty acids, proteins and sometimes specific carbohydrates.
Vitamins and minerals are necessary for the functioning of the immune system, bone formation and many other vital processes. Proteins are important for building and maintaining muscle mass and body tissue. Essential fatty acids contribute to a healthy coat and skin and are important for brain function.
It's important to make sure your dog is getting a balanced diet to ensure they are getting all the nutrients they need in the right amounts. A 'nutrient-rich' diet can help with this.
