Athletic dog​
Large breed can be split into two categories, athletic and robust. The athletic dogs use more energy in their daily activities, even when they aren't exercising, and therefore need a higher calorie intake. Athletic breeds have a ‘cone-shaped’ body with long & powerful limbs and a lean, muscular body. It is typical for them to have a thin abdomen and a deep chest. Examples of athletic dog breeds are Greyhounds, Labrador Retrievers and Dalmatians​
A molecule that prevents harmful oxidation that can lead to inflammation in animals. They are key ingredients in many PURINA® PRO PLAN® diets that support strong immune defences. Vitamin E is a powerful antioxidant.
Amino acids
Building blocks of proteins. There are 22 amino acids. Animals can make non-essential amino acids themselves. Essential amino acids must be supplied in the diet. Cats have 12 essential amino acids while dogs only have 11.


In pet food, bioavailability means the proportion of the absorbed nutrients that are available for use by the body.


​Unit of energy. Ingested in animals through food and drink. Used in activities and body functions. Bodies store the excess as body fat.​
​A large group of foods which includes sugars, starch, and cellulose. Carbohydrates contain hydrogen and oxygen in the same ratio as water (2:1) and can typically be broken down to release energy in the body.​
​Natural prebiotic that stimulates the growth of helpful bacteria in the intestine. Supports healthy digestion and helps control hairball formation.
Crude fibres
A measurement of indigestible fiber in pet diets. Established in a laboratory, it indicates amount of fiber that supports digestive health but has little nutritional value.
State of pet health or a series of symptoms that comprise a diagnosis. i.e. stiff joints in ageing pets suggest a condition of arthritis
Complete food
A complete food contains all the ingredients and nutrients needed to maintain your pet's health — and to give them the right amount of energy. Complete foods are designed to be a single source of nutrition for your pet, without the need for supplements.
Crude ash
A measurement of mineral nutrition in pet food listed on the pack information panel. Crude ash is residual when a sample of the food is burnt. This is the mineral content of the diet.


A macronutrient found within the food, which is particularly important to provide energy. Fat is more energy-dense than carbohydrates or proteins. It also provides insulation to the pet and has a number of other important functions.

Ball of hair that collects in the stomachs of cats when they lick their coats. Can potentially lead to blockage of digestive tract unless controlled.
Referring to the liver
Where molecules have been broken down, so that they are so small they cannot (or very rarely) cause an allergic reaction.
Hypoallergenic pet food excludes common allergens and therefore minimises the risk of an allergic reaction in cats and dogs.


Immune system
A network of organs with cells that recognize foreign substances in a pet’s body and stops them doing harm. Healthy immune systems protect against pathogens, viruses, bacteria, fungi and parasites.
Hormone that regulates absorption of carbohydrates, fats and protein around the body. Essential for glucose supply that gives pets energy.
Intestinal flora
Healthy organisms in the animal gut consisting of bacteria, fungi and yeast. Intestinal flora supports healthy digestion, immunity and the synthesis of vitamins and minerals.

Food ingredients that stimulate the growth of healthy microorganisms especially in the gut. Some occur naturally. Other essentials are digested through PURINA® PRO PLAN® diets.
Probiotics are live microorganisms which, when consumed, improve and/or restore the gut microflora and help to improve digestive health. Supplementing diets with added probiotics helps ensure a balance of healthy microorganisms in the animal gut.
A macronutrient found within the food, composed of amino acids. Protein is the building block for body tissues including muscle, hair and coat, and also important for immune system support.

By law, these ingredients must come from animals which have been inspected under veterinary supervision and passed as fit for human consumption, but they are often surplus to the requirements of the human food industry.
