Does it typically not matter how many ingredients are in dog food as long as they are quality ingredients? Why or why not?

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Chloe, what a great name for a Cavalier. As you know there are so many diets out there it's hard for anyone to keep up with all of them. What matters is that the diet is nutritionally balanced for the particular life stage of the pet, their body condition score, and their activity level. Diets vary in content, number of ingredients, energy density, fillers/additives, supplements, vitamins/minerals, etc. Some diets are what are called Limited Ingredient diets and these are for pets that may have food problems with certain foods such as a sensitivity or even an allergy to certain proteins. The grain feed fad appears to be just that. Since many humans now are cutting out grains, the pet food manufacturers have jumped on that as a marketing ploy but no evidence exists that grains in general are a problem for most pets. There are cases where pets do better without grains according to the owners. These diets tend to be higher in price and again, like I said, a marketing ploy. So bottom line, look for a diet that Chloe enjoys eating, is appropriate for an adult small-medium breed dog which fits her activity level, and fits your financial budget. Some nutritionists now believe that switching dog foods and brands occasionally (with a very slow transition to the new diet over a 2 week period) is good for pets since no one diet is appropriate for an individual pet. I hope this helps and gives you some guidance. The diets with fewer ingredients are usually meant for pets that are having medical problems or problems associated with their diet. Good Luck with Chloe.
