Raw Feeding vs Dry Kibble: The Truth Every Dog Owner Needs to Know

Claim: Kibble is full of fillers and low-quality ingredients

This is sometimes true — of cheap, budget kibble. Brands that use vague ingredient labels like “animal derivatives,” cereal fillers, and artificial additives are rightly criticised. But tarring all kibble with the same brush is like saying all human food is junk food because McDonald’s exists.

A premium working dog kibble lists specific, high-quality protein sources with transparent ingredient declarations. While regulatory terminology such as “Meat and Animal Derivatives” is used in some complete dog foods — including some Wonderdog diets — what matters is whether the manufacturer specifies exactly which species are included. At Wonderdog, we guarantee that the specific protein sources are always clearly detailed within the ingredients — for example, our Original recipe specifies Beef, Chicken, Lamb and Pork within the declaration. No mystery meat. No vague sources. Just honest nutrition at honest prices. Our Wonderdog Special and Wonderdog Original ranges deliver 24% protein and 12% fat — nutritional profiles built for dogs that actually work for a living.

Claim: Raw food is more nutritious because it isn’t cooked

This claim sounds compelling but misunderstands how nutrition works. Cooking does alter some nutrients — but it also increases the digestibility of protein and carbohydrates, meaning the dog can actually absorb and use more of what it eats. The extrusion process used to make quality kibble is carefully controlled to preserve nutritional value while ensuring the food is safe, stable, and digestible.

Raw feeding proponents often compare their diet to the “ancestral” diet of dogs, claiming kibble has dramatically lower protein and higher carbohydrates. In reality, a good working dog kibble can contain 24–30% protein on a dry matter basis — far higher than many raw diets once water content is accounted for. The moisture content of raw food (typically 60–70% water) inflates the apparent protein percentage significantly.

Claim: Raw feeding leads to healthier coats, better digestion and more energy

These are the most frequently cited benefits by raw feeding advocates, and they are almost entirely anecdotal. Owner-reported improvements in coat condition, stool quality, and energy levels are subject to enormous bias — people who switch to raw are typically more engaged with their dog’s health in general. They may also be switching away from genuinely poor quality cheap kibble, so the improvement reflects a better diet, not the raw aspect specifically.

A 2021 peer-reviewed study published in Frontiers in Veterinary Science that directly compared clinical health markers in raw-fed versus kibble-fed dogs found only a “slight” improvement in coat condition score in the raw-fed group — and notably, raw-fed owners were significantly more likely to use dietary supplements and undertake sporting activities with their dogs. In other words, the lifestyle around the food matters as much as the food itself.

Working dog owners who feed Wonderdog regularly report outstanding coat condition, firm stools, and exceptional energy levels. That is what a high-quality, properly formulated kibble delivers.

Claim: Kibble causes obesity, diabetes, and chronic disease

This claim typically cites cheap, high-carbohydrate, low-quality kibble — and lumps all dry dog food together. It’s the equivalent of blaming all human food for obesity because some people eat nothing but ultra-processed snacks.

Obesity in dogs is caused by overfeeding relative to exercise — regardless of diet type. Raw-fed dogs can absolutely become obese if fed too much. A precisely measured, high-protein, appropriately calorie-dense kibble fed according to the feeding guidelines is not a pathway to obesity. It is a pathway to a lean, fit, healthy dog.
