In the world of dog nutrition, the options seem endless. With pet owners increasingly focused on the quality and method of food processing, two options have gained popularity: freeze-dried raw and dehydrated dog foods. Both are unique in their preparation and offer distinct benefits. Here, we’ll delve deep into the differences, advantages, and estimated costs associated with each type of dog food.

1. Introduction to Freeze-Dried Raw Dog Food

Freeze-dried raw dog food undergoes a process where it’s frozen and then has most of its moisture removed under a vacuum, essentially “locking in” the nutrients and flavor of the raw ingredients.


  • Optimal Nutrient Retention: Due to the minimal processing, essential nutrients, vitamins, and enzymes are preserved.
  • Long Shelf Life: The removal of moisture inhibits bacterial growth, allowing the food to last for long durations without preservatives.
  • Palatability: Many dogs find the taste of freeze-dried raw food appealing due to its retention of natural flavors.

Estimated Cost: Typically, freeze-dried raw dog food can cost between $25 to $45 per pound, but this can vary based on brand, ingredient quality, and location.

2. Introduction to Dehydrated Dog Food

Dehydrated dog food involves the removal of moisture using warm airflow. Unlike freeze-drying, it involves some level of cooking, albeit at lower temperatures.


  • Longevity: Like freeze-dried food, dehydrated dog food boasts a long shelf life, without the necessity of artificial preservatives.
  • Ease of Digestion: The mild cooking process can make some ingredients more digestible.
  • Lightweight: The absence of moisture significantly reduces the food’s weight, making it convenient for storage and transport.

Estimated Cost: On average, dehydrated dog food may range from $15 to $35 per pound, with variations depending on brand and ingredient composition.

3. Nutritional Differences

  • Freeze-Dried Raw: By bypassing the cooking process, freeze-dried food retains more of its original nutrients, enzymes, and proteins in its natural state.
  • Dehydrated Food: The gentle heating process might reduce some raw nutrients but can make certain elements more bioavailable, aiding digestion.

4. Preparation Time

  • Freeze-Dried Raw: This can be fed as-is or rehydrated quickly with water to restore some moisture.
  • Dehydrated Food: Requires a more extended rehydration time, usually demanding a mix with water several minutes (or even hours) before feeding.

5. Shelf Life and Storage

  • Freeze-Dried Raw: With proper storage in a cool, dry place, freeze-dried raw dog food can last for years.
  • Dehydrated Food: While also long-lasting, some dehydrated foods might have a slightly shorter shelf life than their freeze-dried counterparts.

6. Palatability and Texture

  • Freeze-Dried Raw: Maintains a closer resemblance to fresh raw food in taste and texture.
  • Dehydrated Food: Offers a more chewy texture which some dogs might find appealing, especially as a treat.

7. Safety and Bacteria

  • Freeze-Dried Raw: The process minimizes bacterial risks, but it’s essential to buy from reputable brands to ensure optimal food safety.
  • Dehydrated Food: The mild cooking process further reduces potential pathogens, offering a slightly elevated safety profile.

8. Dietary Restrictions and Allergies

  • Freeze-Dried Raw: Commonly grain-free and crafted with limited ingredients, making it ideal for dogs with specific sensitivities.
  • Dehydrated Food: Many options cater to dogs with dietary restrictions, and mild cooking can sometimes benefit dogs with certain allergies.

9. Environmental Considerations

  • Freeze-Dried Raw: The freeze-drying process can be energy-intensive but results in lightweight products, thus reducing transport emissions.
  • Dehydrated Food: Uses less energy in the drying process compared to freeze-drying but yields a slightly heavier end product.


Both freeze-dried raw and dehydrated dog foods offer excellent alternatives to traditional kibble or wet foods. While freeze-dried options provide a nearly unaltered raw diet, dehydrated foods strike a balance between raw and cooked, offering some unique advantages of their own. Your choice will depend on your dog’s dietary needs, your budget, and personal preferences. As always, consult a veterinarian when contemplating significant dietary changes for your furry friend.


Frequently Asked Questions About Freeze-Dried Raw Dog Food vs. Dehydrated Dog Food

1. What is the main difference between freeze-dried raw and dehydrated dog food?

Freeze-dried raw dog food is made by freezing the food and then using a vacuum process to remove the moisture, preserving most nutrients and enzymes. Dehydrated dog food is created by applying gentle heat to remove moisture, which can degrade some heat-sensitive nutrients. Both processes extend shelf life but have different impacts on the food’s nutritional profile.

2. Which is more nutritious: freeze-dried or dehydrated dog food?

Freeze-dried dog food tends to retain more of the original nutrients found in raw ingredients because the process does not involve heat, which can break down vitamins and enzymes. Dehydrated dog food, while still nutritious, may lose a portion of its nutrient content due to the heat used during the dehydration process.

3. Is freeze-dried or dehydrated dog food more expensive?

Freeze-dried dog food is generally more expensive than dehydrated due to the complex machinery and energy required for the freeze-drying process. Dehydrated dog food is typically less costly to produce, making it a more budget-friendly option for pet owners.

4. Do either freeze-dried or dehydrated dog foods require refrigeration?

Neither freeze-dried nor dehydrated dog foods require refrigeration due to their low moisture content, which inhibits bacterial growth. Both are shelf-stable and convenient for storage and travel, making them popular choices for pet owners.

5. Can freeze-dried and dehydrated dog foods be used as a complete meal?

Both freeze-dried and dehydrated dog foods can be formulated to provide complete and balanced nutrition for dogs. However, it’s important to check that the product is labeled as a complete meal and not just a topper or treat.

6. How do you prepare freeze-dried and dehydrated dog foods?

To prepare freeze-dried dog food, you typically add water and allow it to rehydrate for a few minutes. Dehydrated dog food also requires rehydration with warm water, but it may take a bit longer to absorb the water and become ready to serve.

7. Are freeze-dried and dehydrated dog foods suitable for all dogs?

Freeze-dried and dehydrated dog foods are generally suitable for all dogs, but it’s essential to choose a formula that matches your dog’s specific nutritional needs. Some dogs with health issues may require a specialized diet, so consulting with a veterinarian is recommended.

8. How long do freeze-dried and dehydrated dog foods last once opened?

Once opened, freeze-dried dog food typically lasts around a month when stored properly in an airtight container. Dehydrated dog food can last a similar length of time but always refer to the manufacturer’s guidelines and use your judgment based on the appearance and smell of the product.

9. Can I feed my dog both freeze-dried and dehydrated dog foods?

Yes, you can feed your dog a combination of freeze-dried and dehydrated dog foods, as long as you ensure that their overall diet is balanced and meets their nutritional requirements. Some pet owners use one as the main meal and the other as a supplement or treat.

10. What should I consider when choosing between freeze-dried and dehydrated dog foods?

When choosing between freeze-dried and dehydrated dog foods, consider factors such as your dog’s taste preferences, any specific health concerns, the cost, and your convenience for preparation and storage. It’s also wise to think about the environmental impact of the production processes and the sustainability of the ingredients used.
