Royal Canin Approach

Kibble Science

What’s in a dry food kibble? More than you might think.

Kibble Shape and Size

See for yourself why a kibble's size, shape and texture can positively improve the health of your pet. 

Royal Canin is a leader in kibble research and development. Extensive development at the Royal Canin campus in France and use of advanced equipment such as the Texturometer – a tool that measures kibble hardness and the amount of force required to chew or break it – allow us to create specifically shaped kibble to meet the needs of different breed's ability to pick-up and chew our product.

We also take size, shape, texture and density into consideration when developing our kibble and adapt it to the specific characteristics of each dog or cat breed's needs. Labrador Retrievers, for example, are known for eating food very quickly, without chewing. Through extensive research, we developed a doughnut-shaped kibble that is designed to encourage chewing and works to slow down the speed of ingestion.

The Persian cat, on the other hand, is known for its long, beautiful coat and flat (brachycephalic) face. Persians use the lower part of their tongue to pick up kibble, so we created an almond-shaped kibble that is easier for them to eat.

A cat's or dog’s size and age is important when it comes to kibble size and texture. For example, the kibble for a giant breed adult dog is much larger and more brittle than the kibble for a miniature breed puppy, which needs smaller, softer pieces.

So why is having specialised kibble shapes so important?


Because the kibble's shape and size can impact many things like:

  • Dental health - It is important that the cat or dog’s teeth penetrate the kibble so that a 'brushing effect can be achieved. This may help to reduce plaque, which can lead to tartar and encourages good oral health.
  • Digestion - The more a cat or dog has to chew the kibble, the slower the ingestion speed, which can aid in digestion.
  • Satisfaction - Kibble density can help to alleviate hunger between meals by creating a sense of fullness. This can help cats and dogs feel satisfied and helps maintain a healthy weight.
  • Palatability - Dogs and especially cats are sensitive to how a food feels in their mouths. The right kibble or kibble texture can help accentuate a food’s flavour and can help to positively enhance the feeding experience. 

We do not develop our foods based on buyer (human) trends, but instead develop every diet according to what we learn from cats and dogs. That is why you'll never find Royal Canin kibble shaped like tiny bones or fish: We make different types of uniquely shaped kibble specifically designed for the needs of your cat or dog.
