Dehydrated dog treats are generally safer than raw treats, primarily because the drying process reduces moisture to levels that inhibit bacterial growth. The nutritional profiles are similar since both are minimally processed, but the gap in food safety is significant enough that most veterinary organizations recommend processed options over raw.
Pathogen Risk: Where the Two Diverge
The most important difference between dehydrated and raw treats isn’t nutrition. It’s contamination. An FDA study analyzing nearly 400 pet food samples found stark results: of 196 raw pet food samples, 15 tested positive for Salmonella and 32 for Listeria monocytogenes. Among 190 jerky-type treats (including chicken jerky, pig ears, and bully sticks), zero tested positive for either pathogen.
That’s not a small difference. Raw treats carry live bacteria that can sicken your dog and, just as importantly, sicken you and your family through handling. The American Veterinary Medical Association formally discourages feeding any raw or undercooked animal-source protein to dogs and cats, citing risks from Salmonella, Campylobacter, E. coli, Listeria, and other pathogens. Their position applies to raw treats just as it does to raw diets.
How Dehydration Controls Bacteria
Dehydration works by pulling water out of the meat until the remaining moisture is too low for bacteria to reproduce. The FDA uses a measurement called water activity to gauge this. Foods with a water activity of 0.85 or below are considered shelf-stable because most dangerous organisms, including the one that causes botulism, need levels of 0.93 or higher to grow. A properly dehydrated treat falls well below that threshold.
There’s a catch, though. Dehydration alone doesn’t kill all bacteria. It just stops them from multiplying. The USDA recommends heating meat to 160°F (and poultry to 165°F) before dehydrating, because bacteria like E. coli can survive drying temperatures of up to 145°F for as long as 10 hours. Once meat begins to dry, surviving bacteria actually become more heat-resistant, making them harder to kill later in the process. Commercial manufacturers with proper food safety protocols typically include this pre-heating “kill step,” but homemade dehydrated treats made in a standard food dehydrator (which usually operates at 130°F to 140°F) may not reach safe temperatures.
This means commercially produced dehydrated treats are considerably safer than homemade ones. If you’re making treats at home, the USDA advises steaming or roasting the meat to the correct internal temperature first, then transferring it to the dehydrator.
Nutritional Differences Are Minimal
Both raw and dehydrated treats are single-ingredient or minimally processed products, so their nutritional starting point is essentially the same piece of meat, organ, or fish. Dehydration does concentrate nutrients by removing water, which means a dehydrated chicken strip contains more protein per ounce than the same strip served raw. But your dog isn’t eating the same volume of each. A dehydrated treat is lighter and denser, so the actual nutrient intake per treat is comparable.
Some advocates of raw feeding argue that heat damages enzymes and certain vitamins. This is technically true for heat-sensitive nutrients like some B vitamins, but the losses during low-temperature dehydration are modest. Dogs synthesize many of their own enzymes, and treats are a small fraction of overall diet. The nutritional trade-off is negligible compared to the food safety advantage.
Storage and Convenience
Raw treats need to stay frozen or refrigerated at all times. You thaw them before serving, and any leftovers go back in the fridge. Surfaces, hands, and bowls that contact raw treats need thorough cleaning to prevent cross-contamination, the same precautions you’d take with raw chicken in your own kitchen.
Dehydrated treats are far more practical. Stored in an airtight container in a cool, dark place, lean meat jerky like chicken or turkey lasts two to three weeks at room temperature. Refrigeration extends that to about a month, and freezing can keep them fresh for up to six months. Fruit and vegetable-based dehydrated treats typically last about two weeks at room temperature. No thawing, no special handling, and significantly less risk of spreading bacteria around your kitchen.
When Raw Treats Still Carry Risk for Your Dog
Healthy adult dogs handle bacterial exposure better than puppies, senior dogs, or immunocompromised animals. Their digestive tracts are shorter and more acidic, which helps neutralize some pathogens. This is why some dogs eat raw treats without obvious illness. But “without obvious illness” isn’t the same as safe. Dogs can shed Salmonella in their stool for days without showing symptoms, creating a transmission risk for children, elderly family members, or anyone with a weakened immune system.
The risk isn’t limited to the dog eating the treat. It extends to anyone who touches the treat, the dog’s mouth, or surfaces the treat contacted. For households with young children or immunocompromised members, this is a meaningful consideration.
Choosing a Safer Dehydrated Treat
Not all dehydrated treats are equally safe. Look for products from manufacturers that follow documented food safety processes, which typically means companies that can confirm their treats undergo a heat kill step before or during dehydration. Single-ingredient treats (just meat, no fillers or additives) offer the closest nutritional profile to raw without the bacterial load.
If you make treats at home, use a food thermometer to verify the meat reaches 160°F (165°F for poultry) before it goes into the dehydrator. Maintain a dehydrator temperature of at least 130°F to 140°F throughout the drying process, and store finished treats in airtight containers. Skipping the pre-cook step leaves your treats in a gray zone where pathogens may survive the entire drying process.
