Potato Protein
This ingredient is a source of protein that can contain as much as 75% protein. It is also an additional source of carbohydrates.
Pea Protein
This ingredient is rich in essential amino acids such as methionine, tryptophan, and valine. It is also a source of essential vitamins, minerals, and digestible fiber.
Bananas
This is a low-calorie ingredient that can be highly beneficial in a dog’s diet. Bananas are a source of potassium, magnesium, Vitamin C, essential B6 vitamins, digestible fiber, copper and biotin, all of which can help support a healthy immune system.

This is a rich source of fat that contains omega 3 and 6 fatty acids. It can help support healthy skin, a shiny coat, a healthy immune system, and healthy cardiac function.
Salt
While I am personally not a fan of salt in dog food, it is kind of important. For starters, sodium is used to help the body produce hydrochloric acid, a compound essential to digestion. However, in excess, salt can lead to obesity and cardiac issues.
