Have you ever had astronaut ice cream? That dry, room-temperature treat offered at science centers and space camp?
Although little more than a novelty, these snacks are made with the same technology used to prepare food for space travel – by removing the water, the food weighs less and takes up less space.
Called freeze-drying, the process used to create these treats is also used to create freeze-dried dog food.
Many dog owners are curious about these foods, and are considering making the switch to them. Read on to learn about the ins and outs of freeze-dried foods; we’ll even recommend five great options for those who decide to make the switch.

Freeze-Dried Dog Food Benefits: Why Do Fans Love It?
There are several benefits to feeding your pooch freeze-dried dog food, including:
- High Quality Ingredients. Freeze dried diets are typically comprised of an extremely impressive slate of ingredients, including muscle meat, organs and ground bones (some also include freeze-dried fruits and vegetables). Most are also made without artificial additives.
- Raw Diet Alternative. Many freeze-dried feeders begin doing so as an alternative to providing a raw diet. Raw diets can be difficult and laborious to assemble and prepare, but freeze-dried foods are often as easy to serve as kibble.
- Long Shelf Life. Additionally, freeze-dried foods often have ridiculously long shelf-lives, which makes them handy to keep around for emergencies. For example, you don’t want to run out of dog food if you find yourself snowed in for a week or if you live in a hurricane-prone region, in which the grocery store shelves completely empty every time a storm threatens.
- Dogs Simply Adore Freeze-Dried Food. Aside from everything else, most dogs find freeze-dried foods to be drool-inducingly delicious. In fact, some people use them as healthy (if somewhat high-calorie) treats.
Note that some dogs will produce much less waste after switching to a freeze-dried diet, as they often contain less fiber than typical kibble. Much more of the food is converted into new tissue and energy.
What Are the Downsides to Freeze-Dried Foods?
There are two primary downsides to freeze-dried foods. They may be deal-breakers for some owners, while others are willing to overlook these downsides. We’ll discuss both below.
Freeze-Dried Foods Are Expensive
The single greatest problem with freeze-dried foods (and dehydrated foods to a lesser extent) is their expense – every product on the market is very pricey when compared to dry (cooked) kibble.
However, it is important to remember that most dehydrated foods swell to 3 to 5 times their original size once rehydrated — so don’t be thrown off by their small packaging.
Since freeze-dried dog food can get quite pricey, a lot of owners end up using freeze-dried foods as “toppers,” by serving them with other, more affordable foods. Do note that some manufacturers discourage this kind of use, so be sure to consult the feeding instructions before using a food in this manner.
Freeze-Dried (Raw) Foods May Be Contaminated with Bacteria
Raw meats are often contaminated with bacteria that can make you or your pooch sick. That’s part of the reason humans cook our food — doing so keeps us healthy.
Broadly speaking, dogs don’t appear to be quite as susceptible to illness-causing bacteria as humans are. But they still can and do get sick from time to time after consuming raw meat.
Accordingly, the raw meat included in some freeze-dried foods may cause some dogs to fall ill.
It is true that freeze-drying removes the bulk of the moisture from a piece of meat, and therefore reduces the rate that bacteria can reproduce. This may make some freeze-dried foods slightly safer than completely unprocessed, raw foods. However, once you pour some water on your dog’s freeze-dried dinner, the bacteria can begin reproducing again.
Ultimately, we’d encourage you to discuss freeze-dried foods with your vet before making the switch. The risks they present may be acceptable for some dogs, while they may be too dangerous for others.
What’s the Difference Between Dehydrated and Freeze-Dried Foods?
Although freeze-dried and dehydrated foods are broadly similar products, and are both comprised of raw foods that have had the bulk of their water removed, they do differ in several key ways.
With dehydrated food, the water is removed from food by simply placing the food in a low-heat environment for an extended period of time.
This is the same drying process that many people use at home to make jerkies and dehydrated fruit treats. In this process, the water begins as a liquid, turns into a gas, and then slowly evaporates from the food.
The use of heat is noteworthy, as it tends to cause the food to undergo a few structural changes. Whether or not this has a negative impact on the nutritional content of the food is not yet known, but raw food devotees often consider this an important distinction.
By contrast, freeze-dried foods are not heated at any point in the manufacturing process.
The freeze-drying process begins with already-frozen foods, which are then placed in large machines that lower the atmospheric pressure around the food. This causes the water to sublimate (transition from ice directly to gas) and diffuse out of the food.
This means that freeze-dried foods have not been cooked at all – a fact many raw-food feeders greatly appreciate.
Additionally, because the food’s structure remains largely intact (aside from shrinkage), the ingredients still resemble their original shape. This makes it easy to look at a pea, for example, and know exactly what it is.
Freeze-Dried Foods vs Totally Raw Foods
Owners may also find themselves wondering about the difference between freeze-dried dog food and raw dog food.
Most freeze-dried and dehydrated foods are made with raw meat (technically, the meat used in dehydrated foods is exposed to heat, so it becomes “cooked” during the manufacturing process).
However, the removal of water as part of the freeze drying and dehydration process makes it possible to store these foods safely without refrigeration. Bacteria require moisture, so by removing the bulk of the water from the foods, they aren’t as likely to spoil.
So, while freeze-dried raw and dehydrated raw dog foods often resemble typical dog foods (some are a bit more like a bag of uncooked oatmeal), completely raw dog foods require packaging like the raw meats you buy at the grocery store – they’re essentially the same thing.
All of this means that you can’t store completely raw dog food without refrigeration, and even with refrigeration, these types of raw foods are only going to remain safe for a finite period of time. So, there aren’t very many commercially produced raw (with moisture) foods on the market, and those that are available will be sold in the refrigerated section of your local pet store.
Note that you’ll need to practice very sound hygiene whenever you are handling raw meats. Be careful to avoid cross-contamination and always wash your hands with soap and water once you’re finished.
What to Look for in a Good Freeze-Dried Food
There a number of characteristics to look for in any nutritious dog food, be it freeze-dried or otherwise. Additionally, there are a few additional considerations to keep in mind when contemplating making a switch.
- The best freeze-dried foods feature ingredients that contain plenty of omega fatty acids. Some of the most common ingredients used in this capacity include salmon and flaxseed, as well as assorted vegetable fats, fish oils, and fish meals.
- Most freeze-dried foods are comprised primarily of meats and minerals, but many of the very best recipes also include antioxidant- and fiber-rich fruits and vegetables. Some of the most common examples include cranberries, blackberries, blueberries, spinach, parsley and carrots.
- Although it is rarely a problem when seeking out freeze-dried foods, make sure that you avoid any that contain artificial colors, flavors or additives. These types of ingredients not only invalidate much of the reasoning behind feeding raw food, they are simply unnecessary.
- Whenever possible, select foods made in the USA, Canada, New Zealand, Australia or Western Europe. These countries maintain stricter quality control standards and regulations, which helps ensure your dog’s food will arrive untainted by dangerous or unhealthy pollutants or unidentified ingredients.
- Avoid low-quality, economy products just in order to save a few bucks. Price is always an important consideration when buying expensive, high-quality dog food, and it makes perfect sense to save a few bucks when you can. However, going cheap can be dangerous with freeze-fried foods; one way manufacturers can try to lower costs is through cheaper packaging – if the packaging does not remain airtight, moisture can seep in, leading to bacterial growth.

Are freeze-dried dog foods healthy for dogs?
As long as they’re made with nutritious ingredients, freeze-dried foods can be very healthy options for dogs.
What are the benefits of freeze-dried dog food?
While it isn’t yet clear if the freeze-drying process itself makes these foods healthier than typical kibble, most freeze-dried foods are made with very high-quality ingredients, they rarely contain artificial additives, they are easy to store for a long time, and dogs tend to love the taste.
Are freeze-dried dog foods safe?
Provided that they’re made by an upstanding manufacturer, freeze-dried foods are safe for dogs.
Are freeze-dried dog foods raw?
True freeze-dried foods do contain raw ingredients, and their water is removed without the use of heat. This distinguishes them from dehydrated foods, which are exposed to gentle heat during the manufacturing process.
Can you freeze dry your own dog food?
It is possible to freeze dry your own food, but — realistically speaking — most owners will not be willing to invest the time or money necessary to do so. You’ll either need to purchase expensive equipment or allow the food to dry out in your freezer over the course of several weeks.
Is freeze-dried dog food better than normal dog food?
Nutritionally speaking, it isn’t clear that freeze-dried foods are healthier than normal kibbles (assuming products of similar quality). However, most freeze-dried foods are made with top-notch ingredients, and they often include organ meats. Additionally, they’re great for picky pups who aren’t fond of kibble.
How long do freeze-dried dog foods last?
While all freeze-dried dog foods last quite a while, the exact length of time they’ll remain safe to feed varies from one product to the next. Just consult the manufacturer’s guidelines on the product packaging to be sure.
