Dry Pet Food (Kibble) Myth Busting

All ‘complete’ pet foods regardless of format, are carefully formulated to provide all the nutrients a healthy pet needs for their species and in many cases a particular life stage.

Members of UK Pet Food commit to formulating their diets in line with the FEDIAF Nutritional Guidelines which detail the nutritional needs of dogs and cats at varying life stagesa. In this factsheet we specifically discuss dry pet food (kibble) for dogs and cats to separate out the facts from the myths


Dry pet food is one of the most convenient and commonly used forms of dog and cat food. It is popular among pet owners for its ease of storage, longevity, and affordability. Dry food can be made by extrusion, baking, flaking, or using cold-press methods. Dry pet foods have a significantly lower moisture content than wet foods and are therefore fed in smaller quantities.

Commercially prepared complete dry dog and cat food, from reputable manufacturers, come with a reassurance of nutritional adequacy, quality and safety and must deliver all the necessary nutrients for the species, and life stage, they are intended for. Some products also have added ingredients that may benefit dogs or cats overall health and help with the management of certain conditions such as joint, digestive or skin issues.

As for any other format of pet food, which come with their own pros and cons, dry food could have some limitations. For example, overfeeding and lower intake of water in cats and dogs have been associated with feeding dry food when compared to wet food1 .


ENEFITS OF COMPLETE DRY DOG AND CAT FOOD

  1. Convenient and easy to store: Dry pet food is incredibly convenient as it can be stored without refrigeration and is easy to portion out. 
  2. Longer Lasting: Dry pet food has an increased stable shelf life due to the reduced moisture content. It is however important to ensure the food is stored correctly following any storage guidance on pack. 
  3. Lasts throughout the day: Dry pet foods are also good for those pets who like to eat little and often, and who choose to regularly return to the daily portion of their food as it can be left in the dish longer than other types of foodb.
  4. Affordability: Compared to other forms of dog and cat food, dry products are typically more affordable and are often more cost-effective in the long run, making them a budget friendly option for many pet owners. This could be partly due to the raw materials used in dry pet food and their longer shelf life and lower moisture content lowering transport costs.
  5. Dental Health: The most effective means of keeping dogs’ teeth clean at home is by brushing their teeth regularly. There are also some Dental Health Diets on the market that use special kibble technology to reduce plaque and tartar buildup and keep dogs’ teeth and gums healthierc.
  6. Feeding Enrichment: Kibble is easy to use and integrate into slow and puzzle feeders. Using these interactive feeders can increase the feeding time and contribute to a pet’s mental and physical stimulation and to create feeding enrichment.

These guidelines are peer reviewed by independent veterinary nutritionists throughout Europe and they are updated to include the latest science.

b Please always follow the feeding guidelines on pack and measure the food using an accurate measuring scale to weigh your pet’s daily food portion to avoid overfeeding.

As always, manufacturers and brands must be able to support their claims if asked.

SOME OF THE MOST COMMON MYTHS ABOUT DRY PET FOOD

MYTH 1: ALL DRY PET FOOD IS THE SAME

FACT: Not all dry dog or cat food is created equal. Different manufacturers use different types and quality of ingredients to offer added benefits in addition to meeting the basic nutritional requirements of pets. It is important to read the ingredients list, and claims on the product, and choose what is best for your petd.

MYTH 2: DOGS AND CATS NEED VARIETY IN THEIR FOOD

FACT: While animals do enjoy a variety in their diet, it is not necessary to change their food frequently. Sudden changes in diet can upset your pet’s stomach and cause digestive issues. It is best to stick to a consistent diet that meets your pet’s nutritional needs and give them the occasional appropriate treats. If a change of diet is necessary, this should be done gradually to allow a period of adjustment. This is particularly important for cats that show neophobia (reluctance or avoidance to eat new foods)2

MYTH 3: DRY FOOD IS NOT AS NUTRITIOUS AS WET FOOD

FACT: A complete dry food can be just as nutritious as a complete wet food. Many dry food brands offer a complete and balanced diet that meets all of your pet’s nutritional needs.

MYTH 4: COOKING AND PROCESSING KILLS OFF ALL THE NUTRIENTS AND VITAMINS IN A DRY PET FOOD

FACT: Heat processing, such as cooking or baking, can cause some loss of vitamins, particularly heat-sensitive vitamins like vitamin C and some B vitamins. However, to ensure a complete diet, pet food manufacturers add the necessary vitamins and minerals to their products to make up for any nutrients that may be lost during processing.

Other factors that can affect the nutrient content of pet food include the quality and freshness of the ingredients used, the processing methods employed, and the storage and handling of the finished product.

As with any form of pet food, it is important to choose a balanced and complete diet that provides all the essential nutrients that your pet needs to maintain good health and is appropriate for their age, size and activity level. Additionally, it’s always a good idea to consult with a veterinarian to determine the best diet for your pet’s individual requirements.
