Raw Pet food vs Dry Pet Food - GA Pet Food Partners

raw pet food vs dried kibble, which is best for your pet? In this article, we will look into the pro's and con's of both forms of pet food.

As pet food nutritionists, we often get asked what the difference is between raw pet food vs dry pet food. This post provides you with key information about the benefits of feeding dried kibble versus raw pet food.

Important Nutrition

Raw pet food can be purchased as a complete diet, but many owners choose to feed homemade raw as they believe it is better for their pets. Studies show that 95% of homemade diets were deficient in at least one essential nutrient. Whilst 84% were lacking in multiple nutrients (PFMA, 2020). Dodd et al. (2019) carried out a nutrient analysis of a homemade diet and the impact that this diet had when fed to a puppy. The results show that the diet was deficient in many nutrients as well as an incorrect balance of calcium and phosphorus which resulted in poor skeletal development.

Raw Risk

It has been identified that there is a risk to pet health from feeding homemade raw diets to pets if they are not nutritionally balanced for the specific species and life stage. It has also been identified that there is a risk to human health. When feeding a raw diet, the risk of infection from bacteria increases as both the pet and its owner can be directly exposed to foodborne pathogens. A study looked at 35 commercial raw pet foods and examined the products for contaminants such as salmonellalisteria and E.coli. The study reported that over half of the tested raw food was positive for at least one contaminant (Bree et al., 2018). The study concludes by stating that dry pet food is a safer option for pets and owners alike. The table below summarises the key differences between dry kibble pet food and raw pet food.


  • Low Moisture Content (around 8%)

  • Feed Small Quantities

  • Complete pet foods – meets pet’s nutritional needs in line with FEDIAF Nutritional Guidelines

  • Stable for an extended period of time as long as it is stored in a cool, dry place

  • Pets may drink more as the food is dry

  • Convenient


  • High Moisture Content (65% +)

  • Can be commercially made or homemade

  • Hygiene and cleanliness is important – a risk to human and pet health

  • Short shelf life once defrosted

  • Pets may drink less as the food is wet

  • Convenient in some formats (frozen, complete, raw)

It is not always easy to directly compare raw pet food vs dry pet food because of the difference in the physical state; therefore, it is important to calculate any values on the same “Dry Matter Basis”.

What is Dry Matter?

Dry matter refers to material that remains after the removal of water. The below tables compare the nutritional content of various raw diets to a kibble diet on an “As fed basis” and on a “100% Dry Matter Basis”. The Analytical Constituents can be compared equally by converting both products to the same dry matter.

Analytical Constituents on an “as-fed basis.”

  • Oil: 9%

  • Protein: 12%

  • Fibre: 1%

  • Ash: 2%

Raw Diet B

  • Moisture: 64.6%

  • Oil: 15.7%

  • Protein: 14.6%

  • Fibre: 1%

  • Ash: 4.9%

Raw Diet C

  • Moisture: 74.9%

  • Oil: 5.8%

  • Protein: 14.4%

  • Fibre: 1.8%

  • Ash: 2.9%

Dry Diet A

  • Moisture: 8%

  • Oil: 16%

  • Protein: 28%

  • Fibre: 3%

  • Ash: 9.5%

Analytical Constituents on 100% Dry Matter Basis

Raw Diet A

  • Moisture: 0%

  • Oil: 30%

  • Protein: 40%

  • Fibre: 3.3%

  • Ash: 6.7%

Raw Diet B

  • Moisture: 0%

  • Oil: 44.4%

  • Protein: 41.2%

  • Fibre: 2.8%

  • Ash: 13.8%

Raw Diet C

  • Moisture: 0%

  • Protein: 57.4%

  • Fibre: 7.2%

  • Ash: 11.6%

Dry Diet A

  • Moisture: 0%

  • Oil: 17.4%

  • Protein: 30.4%

  • Fibre: 3.3%

  • Ash: 10.3%

There are many different pet food formats on the market which can sometimes make it hard to decide what is best to feed to pets. The most important message is that the quality of pet food should be measured on the contents of the food rather than the format that it is fed in.
