Raw vs Kibble vs Wet Food — Which Is Best for Your Pet?

Few topics in pet nutrition spark more heated debate than the choice between raw, kibble, and wet food. Raw feeding advocates insist it mirrors a natural diet. Kibble loyalists point to decades of research and convenience. Wet food fans champion hydration and palatability. The truth, as usual, is more nuanced than any camp admits.

This guide examines all three food types through the lens of nutrition science, practical considerations, and cost — so you can make the right choice for your specific pet.

The Great Debate

The pet food industry has evolved dramatically over the past century. Commercial kibble was invented in the 1950s, canned wet food dates back even further to the 1920s, and raw feeding gained mainstream popularity in the 1990s after Australian veterinarian Ian Billinghurst published his BARF (Biologically Appropriate Raw Food) diet framework. Each food type has genuine advantages and real drawbacks. None is universally "best."

Kibble (Dry Food)

The Pros

• Convenience. Kibble is shelf-stable for months, easy to measure, simple to store, and does not require refrigeration. For busy households, this matters enormously.
• Dental benefits. The mechanical action of chewing kibble provides some abrasive cleaning of tooth surfaces. While kibble alone is not a substitute for dental care, it does offer mild benefits compared to soft foods.
• Cost efficiency. Per calorie, kibble is by far the most affordable option. A medium-sized dog can be fed high-quality kibble for around 1.50-3.00 EUR per day, depending on the brand.
• Nutritional completeness. Reputable kibble brands undergo feeding trials and are formulated by veterinary nutritionists. The nutrient profile is consistent from bag to bag.
• Variety and availability. Kibble is available in more formulations than any other food type — breed-specific, life-stage, weight management, prescription, limited ingredient, and more.

The Cons

• Heavy processing. Kibble is made through extrusion, which involves high temperatures (120-200 degrees Celsius) and high pressure. This process can degrade some heat-sensitive nutrients, particularly certain vitamins and amino acids, though manufacturers compensate by adding these back after cooking.
• Low moisture content. Kibble contains only 6-10% moisture. Pets fed exclusively on dry food may not drink enough water to compensate, which is a particular concern for cats, who have a naturally low thirst drive and are prone to urinary and kidney issues.
• Fillers and additives. Lower-quality kibbles rely heavily on corn, wheat, and soy as cheap calorie sources. Some contain artificial colors, flavors, and preservatives like BHA, BHT, and ethoxyquin.
• Palatability. Many pets, especially cats, find kibble less appealing than wet or raw food. Picky eaters may refuse certain dry formulas entirely.

Wet Food (Canned or Pouch)

The Pros

• Hydration. Wet food contains 75-85% moisture, which significantly contributes to your pet's daily water intake. This is especially beneficial for cats and for pets with kidney disease or urinary tract conditions.
• Palatability. The texture, aroma, and flavor of wet food are generally more appealing to pets. For senior animals with reduced appetite or pets recovering from illness, wet food can be the difference between eating and refusing meals.
• Higher protein density. On a dry matter basis, wet food often contains more animal protein and fewer carbohydrates than kibble. This more closely aligns with the natural macronutrient profile for both dogs and cats.
• Fewer preservatives. The canning process itself preserves the food, reducing or eliminating the need for chemical preservatives.

The Cons

• Cost. Wet food typically costs 3-5 times more than kibble per calorie. Feeding a medium dog exclusively on quality wet food can easily reach 5-10 EUR per day.
• Dental concerns. Soft food provides no mechanical tooth cleaning and can stick to teeth, potentially contributing to plaque buildup. Regular dental care becomes even more important.
• Short shelf life once opened. Opened cans or pouches must be refrigerated and used within 2-3 days. This creates food waste if your pet does not finish a portion.
• Storage and waste. Cans and pouches generate more packaging waste and require more storage space than an equivalent amount of kibble.

Raw Food (BARF, Prey Model, Commercial Raw)

The Pros

• Minimal processing. Raw food retains heat-sensitive nutrients, enzymes, and natural food structure that are destroyed during kibble extrusion or canning.
• Bioavailability. Proponents argue — and some studies support — that nutrients in raw food are more readily absorbed. Dogs on raw diets typically produce smaller, firmer stools, indicating higher digestibility.
• Coat and skin improvements. Many pet owners report shinier coats, healthier skin, and reduced allergy symptoms after switching to raw. While anecdotal, this is one of the most consistently reported benefits.
• Dental health. Raw meaty bones provide excellent mechanical cleaning. Dogs that regularly chew appropriate raw bones typically have significantly less tartar buildup than those on soft diets.
• High palatability. Most dogs and cats find raw food extremely appealing. Transitioning a picky eater to raw is rarely a challenge.

The Cons

• Bacterial contamination. Raw meat carries risk of Salmonella, Listeria, E. coli, and other pathogens. This is a risk not just to your pet but to humans in the household, especially children, elderly, and immunocompromised individuals. Studies have found pathogenic bacteria in 20-48% of commercial raw pet food samples.
• Nutritional imbalance. Formulating a nutritionally complete raw diet is genuinely difficult. Homemade raw diets are frequently deficient in calcium, zinc, vitamin D, and essential fatty acids. Even small imbalances, compounded over months, can cause serious health problems. Commercial raw diets solve this but at premium cost.
• Cost. Commercial raw food is the most expensive option, typically 5-15 EUR per day for a medium dog. Homemade raw is cheaper but requires careful formulation and sourcing.
• Inconvenience. Raw food requires freezer storage, careful thawing, meticulous hygiene during handling, and thorough cleaning of bowls and surfaces after every meal.
• Bone hazards. Cooked bones are dangerous, but even raw bones can cause tooth fractures (especially weight-bearing bones from large animals) or gastrointestinal blockages if improperly sized.

Comparing Costs

For a 15 kg medium dog eating approximately 800 calories per day, here is what you can expect to spend on quality brands:

• Kibble (premium): 1.50-3.00 EUR per day (45-90 EUR per month)
• Wet food (premium): 4.00-8.00 EUR per day (120-240 EUR per month)
• Commercial raw: 5.00-12.00 EUR per day (150-360 EUR per month)
• Homemade raw: 3.00-7.00 EUR per day (90-210 EUR per month), plus time and formulation costs
• Mixed feeding (kibble + wet): 2.50-5.00 EUR per day (75-150 EUR per month)

These ranges vary significantly by country, brand, and where you shop. Buying in bulk, using subscription services, or sourcing from local farms can reduce raw feeding costs substantially.

What the Science Says

The scientific evidence on pet food types is less definitive than advocates on any side suggest. Here is what we know:

A 2023 systematic review in the Journal of Animal Science found no consistent evidence that raw diets produce superior health outcomes compared to high-quality commercial foods in healthy dogs. However, the review acknowledged that long-term studies are scarce and most existing research is industry-funded.

The American Veterinary Medical Association (AVMA) officially discourages raw feeding due to bacterial contamination risks, while the British Veterinary Association (BVA) takes a similar stance. However, some veterinary nutritionists argue that properly handled, nutritionally complete raw diets are safe and potentially beneficial.

What is clear from the research: the quality of ingredients and nutritional completeness of the diet matter far more than whether the food is raw, cooked, dry, or wet. A well-formulated kibble will outperform a poorly balanced raw diet, and vice versa.

How to Choose: A Decision Framework

Rather than asking "which food type is best," ask these questions about your specific situation:

1. What is your budget? If cost is a significant constraint, high-quality kibble provides the best nutritional value per euro. You can supplement with occasional wet food or fresh toppers for variety.
2. Does your pet have health conditions? Cats with kidney or urinary issues benefit greatly from wet food's moisture content. Dogs with allergies may improve on limited-ingredient diets in any format. Pets with compromised immune systems should avoid raw food.
3. How much time can you invest? Raw feeding, especially homemade, requires significant time for preparation, sourcing, and cleanup. If your schedule is demanding, kibble or wet food is more practical.
4. Who lives in your household? If you have young children, elderly family members, or anyone with a weakened immune system, the bacterial risks of raw food handling deserve serious consideration.
5. What does your pet prefer? A food your pet refuses to eat provides zero nutrition, regardless of its theoretical quality. Palatability matters. Some cats will not eat kibble; some dogs thrive on it.
