Differences between Wet and Dry Dog Food
Contents
Wet vs. Dry Dog Food[edit]
The choice between feeding a dog wet or dry food involves considering differences in moisture content, nutritional makeup, cost, and convenience.[1][2] Dry food, also known as kibble, is the most common choice among dog owners and is produced by combining and cooking ingredients like meat and grains into a dough, which is then dried.[3][4] Wet food is typically made by grinding and cooking meats, then combining them with a gravy containing other ingredients before sealing it in cans or pouches.[3][4] Both wet and dry foods can provide complete nutrition, but their distinct characteristics may suit different dogs based on age, health, and preference.[3]
Comparison Table[edit]
| Category | Wet Food | Dry Food |
|---|---|---|
| Moisture Content | High (typically 70-85%)[1][5] | Low (typically 6-12%)[1] |
| Nutrient Density | Lower caloric density; may have higher protein and fat on a dry matter basis. | Higher caloric density; often contains more carbohydrates to bind the kibble.[1] |
| Palatability | Generally more palatable due to strong aroma and flavor.[1] | May be less appealing to picky eaters.[2] |
| Dental Health | Can contribute to plaque buildup without regular dental care. | The crunchy texture can help reduce plaque and tartar.[3] |
| Shelf Life (Unopened) | Long (typically 2-3 years). | Long (typically 12-18 months). |
| Shelf Life (Opened) | Short (must be refrigerated and used within a few days). | Longer (can last for several weeks if stored properly). |
| Cost | Generally more expensive per serving. | Typically more cost-effective, especially for larger dogs.[2] |
| Convenience | Requires refrigeration after opening; can be messier.[4] | Easy to store and measure; can be left out for longer periods. |
Hydration[edit]
A significant difference between wet and dry food is the water content. Wet food's high moisture level (around 75-78%) contributes to a dog's overall hydration.[1] This can be particularly beneficial for dogs that do not drink enough water or have health conditions like kidney or urinary tract issues that require increased fluid intake. Dry food has a much lower moisture content, around 10%, meaning dogs on a kibble-based diet need to drink more water to stay adequately hydrated.[1]
Nutritional Considerations[edit]
On an "as fed" basis, dry food labels often show higher percentages of protein and other nutrients.[1] However, when compared on a "dry matter basis," which removes the water content from the equation, wet food can have similar or even higher levels of protein and fat. Dry food formulations generally contain more carbohydrates and starches, which are necessary to form the kibble's shape and structure.[1] In contrast, wet food typically has lower carbohydrate levels.
The high-temperature cooking process used for dry food can reduce the nutritional value of some ingredients.[3] Wet food is cooked within its sealed container, which helps to preserve its freshness and nutrients.[3][4]
Dental Health[edit]
Dry food is often cited as being better for a dog's dental health. The abrasive texture of the kibble can help scrape away plaque and tartar as the dog chews.[3] Some studies suggest that dogs consuming dry foods have less plaque buildup compared to those eating wet foods. However, this benefit can be limited if a dog swallows its kibble without much chewing. Specialized dental diets with larger kibble sizes may be more effective. Wet food's soft texture does not provide the same mechanical cleaning action and may contribute more to dental issues if not paired with regular brushing or other dental care.[2]
