Can Freeze-Dried Liver Treats Cause Diarrhea in Dogs?

In small amounts, liver treats won’t cause any reaction in your dog’s tummy. But they love the taste that you’ll find them begging for more – and yourself giving more than one.

That’s when problems with giving them the treats happen. Liver in itself is already nutrient-rich, so imagine how rich it is freeze-dried. If your pup’s tummy is sensitive, or you’re giving the treat for the first time, go slow. Start with one treat a day, especially for puppies or small breeds. Cut the treat in half if you have to. Then observe for any unpleasant reaction. Don’t give them any other treats even strawberries while introducing this one.

If diarrhea persists for more than two days, stop the treat and consult your vet.

How To Freeze Dry Liver for Dog Treats

Now that we have your interest in freeze-dried liver treats, it’s time to start making your own.


Prepping is important whether you’re freeze-drying lamb, chicken, or beef liver. You’ll get a strong, earthy, metallic smell, and that’s okay. If the liver has a strong putrid smell that’s a touch sour, it means your liver isn’t good.

Slicing the liver can be challenging because it doesn’t have the same firmness as meat. To make them easy to slice, freeze them for just an hour. Not to turn them into a solid block of ice, but make them firm enough for you to cut. This is helpful, especially if you don’t have sharp knives around.

Slice them into wedges or steaks that are 3/4 of an inch thick. The slices can be thinner but not so thick that they’re higher than the freeze-dryer trays.

After cutting, wash the slices of liver thoroughly. Don’t mind the murky run-off from the organ. It’s okay and should be expected. Drain the liver slices well and pat them dry with paper towels.


Line your freeze-dryer trays with parchment paper or silicone liners. This helps keep the liver from sticking to the tray when you freeze dry.

Place the liver slices on the trays, spacing them at 1/4 or 1/2 inch. Avoid stacking the liver so that your freeze-dryer can work efficiently. Place the trays in your deep freezer and let the liver steaks freeze for 12 hours or overnight.

Freeze Drying Liver Treats

Freeze drying is easy when you have your own Harvest Right freeze dryer.

  1. Turn on the machine and let it know you’ve pre-frozen the liver.
  2. Pre-freeze the unit for 15-30 minutes.
  3. When it’s ready, close the valve and load the frozen trays in.
  4. Press continue, and it will start freeze-drying.
  5. When it’s done, open the valve, ensuring the hose doesn’t touch any water. This will release the pressure inside the chamber, allowing you to open the door.
  6. Take out the trays and check for dryness.

How Will I Know That They’re Done?

The freeze-dried liver treats should be dry, hard, and crumbly to the touch. It should snap easily between your hands and feel dry even in the middle. If some pieces feel soft, moist, and cool, put the trays back and add an extra dry time. About 4 hours would do it.

How Do I Store Them?

Mylar bags are always an excellent choice for storing freeze-dried liver treats. They’re easy to seal and carry around, especially on trips. You can have it with you when you vacation with your dogs and continue their training without interruption.

Mason jars are great as well because they’re impermeable. Using a vacuum sealer, they’re as good as Mylar bags when storing food. The only downside is they’re heavy and take up space. Their transparency is a double-edged sword too. It allows you to see how much treat you have left while letting the light go through. Light breaks down protein and ruins the edibility of the liver.

You need to remember to use oxygen absorbers for a longer shelf life. When using 300cc oxygen absorbers, put 1-2 of them per gallon size of your container.
