Decoding Wet Dog Food: What’s Really in That Can?
Published: 18 Feb 2025
Hello, pet parents!
Does your dog refuse to eat dry kibble? Struggle with dehydration? Or maybe they have dental issues that make chewing difficult? Wet dog food could be the perfect solution. With its soft texture, high moisture content, and rich flavours, it’s an excellent option for picky eaters, senior dogs, and those needing extra hydration. In fact, studies show that over 60% of dog owners mix wet and dry food to create a balanced diet for their pets.
But is wet dog food the right choice for your pup? With four years of experience in canine nutrition, I’ll give you a comprehensive overview of wet dog food—what it is, its key benefits, potential drawbacks, and how it compares to dry food. Let’s dive in!
What is Wet Dog Food?
Wet dog food is a type of dog food that comes in cans, pouches, or trays and has a high moisture content—typically around 70-80% water. Its soft, meaty texture makes it more palatable for dogs.
Wet dog food is made with a balanced blend of ingredients to meet a dog’s nutritional needs. Here’s a breakdown of the key components:
1. Protein Sources
Protein is the foundation of a dog’s diet, supporting muscle growth, energy, and overall health. Common protein sources in wet dog food include:
- Meat: Beef, lamb, pork
- Poultry: Chicken, turkey, duck
- Fish: Salmon, whitefish, tuna
- Organ meats: Liver, kidney, heart (rich in essential nutrients)
2. Carbohydrates
Carbohydrates provide energy and fibre, aiding digestion. Wet dog food may contain:
- Grains: Brown rice, barley, oatmeal
- Vegetables: Sweet potatoes, peas, carrots, pumpkin
- Fruits: Blueberries, apples, cranberries (rich in antioxidants)
3. Fats and Oils
Fats are essential for skin health, a shiny coat, and brain function. Common fat sources include:
- Animal fats: Chicken fat, fish oil
- Plant-based oils: Flaxseed oil, sunflower oil
- Omega-3 and Omega-6 fatty acids: Important for joint and heart health
4. Vitamins and Minerals
Wet dog food is fortified with essential vitamins and minerals to support overall health:
- Calcium & Phosphorus: Strengthens bones and teeth
- Zinc & Iron: Supports immune function and metabolism
- Vitamins A, D, E, & B-complex: Boost vision, energy, and skin health
5. Moisture (Water or Broth)
The high moisture content in wet dog food comes from:
- Water: Keeps dogs hydrated and aids digestion
- Broth (chicken, beef, fish): Enhances flavour and provides extra nutrients
6. Thickening Agents
To maintain texture and consistency, some wet dog foods include natural thickening agents:
- Carrageenan: A seaweed-derived thickener
- Guar gum & Xanthan gum: Helps bind ingredients together
Wet dog food provides a nutrient-dense and highly palatable option for dogs of all life stages. However, ingredient quality varies by brand, so reading labels is key to choosing the best option for your pup.
How Wet Dog Food is Processed?
Wet dog food undergoes a specialized cooking and canning process to ensure it is safe, nutritious, and shelf-stable. Here’s a step-by-step breakdown:
1. Ingredient Selection and Preparation
The process starts with carefully selected ingredients. Then these ingredients are:
- Inspected for quality and safety to meet nutritional standards.
- Chopped, ground, or pureed to achieve the desired texture.
- Blended with water or broth to create the high-moisture consistency of wet dog food.
2. Cooking and Mixing
Once the ingredients are prepared, they are cooked at high temperatures to kill bacteria while preserving nutrients.
- Meat and proteins are often pre-cooked to ensure safety.
- The ingredients are blended into a uniform mixture, sometimes forming chunks or pâté-style textures.
- Essential vitamins, minerals, and fats are added to ensure the food meets AAFCO or brand-specific nutritional guidelines.
3. The Canning Process
After cooking, the wet food is packaged into cans, pouches, or trays. This step is critical for preservation and shelf life.
- The cooked food is placed into sterilized cans, ensuring precise portions.
- Each can is vacuum-sealed to prevent contamination.
- The sealed cans go through a high-pressure heat treatment called retort cooking (similar to pasteurization). This process:
- Eliminates harmful bacteria.
- Extends shelf life without artificial preservatives.
- Keeps the food fresh and safe for months or even years.
4. Cooling and Quality Checks
Once the cans are sterilized, they are rapidly cooled to maintain texture and taste. Before distribution, each batch undergoes:
- Nutritional analysis to ensure balanced nutrient content.
- Safety inspections to check for defects, leaks, or contamination.

Benefits of Wet Dog Food
Wet dog food offers several health benefits, including:
1. Hydration Support
Wet dog food contains about 70-80% moisture, making it an excellent hydration source. This is especially beneficial for dogs that don’t drink enough water or suffer from urinary issues like kidney disease or bladder stones.
2. Highly Palatable for Picky Eaters
The rich aroma, texture, and taste of wet food make it more appealing than dry kibble. Dogs with poor appetites, recovering from illness, or seniors with reduced senses of smell and taste may prefer wet food.
3. Soft Texture for Easy Eating
Wet food’s soft consistency makes it ideal for:
- Senior dogs with weaker jaws or missing teeth.
- Dogs with dental issues like gum disease.
- Puppies transitioning from milk to solid food.
Since it doesn’t require much chewing, it’s easier for dogs with oral pain to eat comfortably.
4. Formulated for Specific Dietary Needs
Many wet dog food formulas cater to dogs with specific health conditions:
- Kidney disease: Low-protein, low-phosphorus formulas to reduce kidney strain.
- Diabetes: High-protein, low-carb recipes to stabilize blood sugar.
- Food allergies or sensitivities: Limited-ingredient and hypoallergenic options.
- Weight management: Low-calorie formulas help control portion sizes while keeping dogs full.
Drawbacks of Wet Dog Food
While wet dog food offers several benefits, it also has some drawbacks that pet owners should consider.
1. Higher Cost
Wet dog food is more expensive than dry kibble. This is due to its higher moisture content, quality ingredients, and packaging costs. For large dogs or multi-dog households, you need more cans of wet food to provide the same amount of actual nutrients as a smaller amount of dry food.
2. Storage Challenges
Once opened, wet dog food requires proper storage to prevent spoilage. Unlike kibble, which can be stored at room temperature, wet food must be refrigerated and used within 24-48 hours; otherwise, it spoils.
3. Less Convenient & Messier
Feeding wet food can be messy, especially if your dog is a sloppy eater. It often leaves behind sticky residue in bowls, requiring frequent cleaning. Additionally, travelling with wet food can be inconvenient since it needs refrigeration and can be bulky.
4. Limited Dental Benefits
Unlike dry kibble, wet food does not provide dental benefits. Without proper dental care, such as brushing or dental treats, dogs on a wet food diet may be at a higher risk for plaque buildup and gum disease.
5. Environmental Impact
The production and packaging of wet food, particularly in cans and pouches, contribute to environmental waste. While many brands use recyclable materials, canned food production requires more resources and energy compared to dry kibble, making it less eco-friendly.
How to Choose the Right Wet Dog Food?
Selecting the right wet dog food is essential for your dog’s health, energy, and overall well-being. Here are key factors to consider:
1. Read the Ingredient List & Guaranteed Analysis
Always check the ingredient list to ensure the food contains high-quality animal protein (like chicken, beef, or fish) as the first ingredient. Avoid artificial preservatives, fillers, and by-products. The guaranteed analysis on the label provides essential information about protein, fat, fiber, and moisture content, helping you compare different options.
2. Consider Your Dog’s Life Stage
Dogs have different nutritional needs at various life stages:
- Puppies need higher protein and fat levels for growth and development.
- Adult dogs require balanced nutrition for energy and maintenance.
- Senior dogs may benefit from lower calories, joint-supporting ingredients (like glucosamine), and easily digestible proteins.
Choose a formula appropriate for your dog’s age to support their specific needs.
3. Address Specific Dietary Requirements
If your dog has health conditions, look for specialized wet food formulas:
- Sensitive stomachs: Limited-ingredient or grain-free options.
- Weight management: Low-fat, high-fiber diets.
- Kidney disease: Low-protein, low-phosphorus formulas.
- Diabetes: Low-carb, high-protein diets to stabilize blood sugar.
4. Consult Your Veterinarian
Every dog is unique, and their diet should reflect their individual needs. Always consult your veterinarian before making a switch, especially if your dog has allergies, medical conditions, or special dietary requirements. They will provide you with personalized advice tailored to your specific needs.
Variations in Ingredient Quality in Wet Dog Food
Not all wet dog foods are created equal—ingredient quality can vary significantly based on sourcing and processing standards. Understanding the difference between human-grade and feed-grade ingredients can help you choose the best option for your dog.
1. Human-Grade Ingredients 🥩🥦
Human-grade wet dog food is made with ingredients that meet USDA and FDA standards for human consumption. This means:
✅ High-quality proteins (real cuts of meat, poultry, or fish)
✅ Fresh vegetables and fruits (without harmful pesticides)
✅ No fillers, by-products, or artificial additives
✅ Stricter quality control during processing
Example: A brand that labels its wet food as “human-grade” must ensure that every ingredient and the entire manufacturing process meet human food standards.
2. Feed-Grade Ingredients 🦴🥩
Most commercial wet dog foods use feed-grade ingredients, which are only approved for animal consumption. These may include:
⚠️ Meat by-products (organs, bones, and rendered meats)
⚠️ Lower-quality protein sources (4D meats: dead, diseased, dying, or disabled animals)
⚠️ Artificial preservatives and fillers
⚠️ Lower oversight in ingredient sourcing
Example: Many budget-friendly brands use feed-grade meats and by-products, which can still provide nutrition but may not be as high quality as human-grade options.
Which Should You Choose?
- Human-grade wet dog food is the best choice if you prioritize premium nutrition with fewer processing concerns.
- If you’re on a budget, high-quality feed-grade options can still provide balanced nutrition—check for real meat as the first ingredient and avoid artificial preservatives.
How to Transition to Wet Dog Food?
Switching your dog to wet food should be done gradually. Dogs have sensitive stomachs, and sudden dietary changes can cause vomiting, diarrhea, or refusal to eat. A gradual transition helps their gut bacteria adapt to the new food and ensures a smooth adjustment. Follow this 5- to 7-day plan:
- Days 1-2: 75% old food, 25% new wet food
- Days 3-4: 50% old food, 50% new wet food
- Days 5-6: 25% old food, 75% new wet food
- Day 7: 100% new wet food
If your dog experiences any digestive issues, slow down the transition by extending each phase by a day or two.
- Mix wet food with dry kibble during the transition to help with texture adaptation.
- Serve wet food at room temperature for better palatability.
- Monitor your dog’s stool quality, appetite, and energy levels during the switch.
Wet vs. Dry Dog Food: A Comparison
Both wet and dry dog food have their own benefits and drawbacks. Below is a quick comparison to help you decide which option best suits your dog’s needs.
