This is a definitive list of ingredients that are used in the pet food industry so that you know exactly what is in your pet's food.


Animal fats are a mixture of fats rendered from different animals. The source of these are diverse and include restaurant grease and factory by-products. The mixture of different animals makes it hard to avoid particular ingredients if your dog has an allergy or intolerance. First you can never be sure which animal fats are present and secondly they can vary batch to batch so that even if your dog can tolerate it, this could be different in a later batch of dog food.

Due to the nature of animal fat, they tend to be preserved with artificial preservatives such as BHT, BHA or Ethoxyquin to prevent rancidity as it is hard to preverse them naturally. Avoid!
Always look for a product with a named fat source i.e. Chicken fat or lamb fat


Ash content is given as a percentage. It isn't an ingredient that is added but the total mineral content of the product after incineration.


Although a good source of protein, beef is known to cause intolerances in some pets. It is also lower down the digestibility scale from chicken, turkey and lamb.


Brewer's yeast is a a by-product from the brewing industry. It contains high levels of vitamin B


This term allows the use of anything that is not classed as a cereal. It is generally waste material from the Human food preparation industry. By the time it is processed at high temperature, it contains no nutritional value except as another fibre source. It is inexpensive to use and is classed as another bulking agent.


Carrots are a good source of beta-carotene, vitamins and minerals.


"Cereals" is a term used to cover many different grains used in pet foods. When you see this as an ingredient, it means that you cannot be certain what is actually in your dog food because they are not using a "named" ingredient. This allows manufacturers to use the cheapest grain available at the time of manufacture and this can change batch to batch. Avoid!


Chicken meat is an good protein source with a balanced amino acid acid mix.
"Fresh" is the term used when the % given is for the meat quantity before processing when it is weighed in its wet form. This can be misleading as you are perceiving the % of wet quantity, yet 2/3 of the water is lost during processing leaving you with a much smaller meat content in the final product.


Chicken meat and meal is an good protein source with a balanced amino acid mix. This is the same as fresh chicken but with the water removed which means that it gives a better guide to the actual quantity in the final product. Can be described as "The dried, clean rendered flesh of the animal with the water and fat removed".


Chicken fat is a high quality fat source that is highly palatable. 


Corn is a frequently used pet food ingredient, however it can be difficult for dogs to digest. Used as a carbohydrate source, it is cheap and could be described as a filler.


"Derivatives of vegetable origin" is a generic term used to describe by-products of vegetable origin. This is yet another term that is commonly used in pet foods that covers many different ingredients so that pet food manufacturers can use the cheapest available. Avoid!

Official definition:
Derivatives resulting from the treatment of vegetable products in particular cereals, vegetables, legumes and oil seeds.


The term "EC permitted additives" covers a large range of different chemicals, allowing a pet food manufacturer to use any of them without having to individually name any of them. This includes artificial colours and flavourings which are known to cause hyperactivity. More worryingly, pet foods using this term can contain preservatives such as BHA, BHT and Ethyoxquin which have been shown to cause cancer. 


Egg is the most digestible source of protein as well as providing vitamins and minerals.


Fish is an excellent quality protein source that is also highly palatable. It also contains good levels of omega 6 and omega 3 which consist of polyunsaturated fatty acids DHA and EPA. DHA is known to help brain function.


Fish oil contains good levels of omega 3 which consist of polyunsaturated fatty acids DHA and EPA. DHA is known to help brain function.


Lamb is a good protein source. It is rich in calcium and a good source of zinc. Lamb meal is used in many hypo-allergenic dog foods.

Definition of meal:
Meals are prepared by the heating, drying and grinding whole or parts of warm blooded land animals from which the fat has been partially extracted or physically removed. The product has to be free from hooves, horn, bristle, hair and feathers as well as digestive tract content.


"Meat and animal derivatives" is a generic term that covers all animals and parts such as heads, feet, guts, lungs, hair, feathers and wool! This term can be used to hide undesirable ingredients and allows the manufacturer to change the meat source from batch to batch to whatever is the cheapest available at the time of manufacture. Meat and animal derivatives are used in many successful pet foods because most consumers don't know any better. Avoid!

Official definition of meat and animal derivatives:
All the fleshy parts of slaughtered warm-blooded land animals fresh or preserved by appropriate treatment, and all products and derivatives of the processing of the carcase or parts of the carcase of such animals.


Oats are a versatile ingredient used as a fibre source, also providing a good source of energy.


Potato is a high quality carbohydrate. It is often used as an alternative to rice and therefore a good ingredient for dogs with rice intolerances.


Clean parts of slaughtered poultry, such as heart, lungs, liver, kidneys, feet, abdomen, intestines and heads.


Propylene Glycol is a preservative that is used in pet foods. It is best avoided as it known to cause problems such as hair loss, dull coat, diarrhoea etc.


Rice is the most digestible of all grains and is known to be low in allergy risk and so is found in many "hypo-allergenic" pet foods. Rice is rich in unsaturated fatty acids and B Vitamins.


Rosemary is used in pet foods as a preservative as it is a natural antioxidant.


Seaweed is a great source of iodine and minerals


Soybeans are widely used in dog foods as a protein source. However, Soy is commonly known as a cause of food allergies in dogs.


Beet pulp is a good source of insoluble and soluble fibres.


Tocopherols (vitamin E) are a naturally occuring antioxidant which is used to preserve pet foods. Tocopherols are often made from edible vegetables oils. The use of Tocopherols in a dog food is a good indication of a better dog food.


Official definition:
All products of vegetable origin in which the proteins have been concentrated by an adequate process to contain at least 50% crude protein, as related to the dry matter, and which may be restructured or textured.


Wheat is a grain used as a carbohydrate source in dog foods, however it is associated with causing allergies in many dogs.
