In this comprehensive guide, learn how to easily freeze dry beef liver at home to create tasty training treats and rewards your pup will go wild for.

Why Choose Beef Liver for Homemade Dog Treats?

Beef liver is a nutritional powerhouse for dogs. Here are some of its stellar benefits:

• Excellent source of protein – supports strong muscles and energy
• Loaded with essential vitamins and minerals like iron, copper, niacin, folate, riboflavin and more
• Contains high levels of vitamin A for healthy skin, coat and eyesight
• Natural source of glucosamine for joint health
• Provides vitamin B12 for proper nerve and brain function
• Highly digestible protein for dogs sensitive to grains, fillers or additives

Beef liver’s savory umami flavor is naturally irresistible to most dogs. And freeze drying intensifies the mouthwatering smell and taste they love.

How Does Freeze Drying Preserve Nutrition in Liver?

Freeze drying, also known as lyophilization, is a low temperature dehydration process. Beef liver is frozen at very cold temperatures under vacuum conditions. The frozen water inside the liver sublimates – meaning it transitions from solid ice directly into a gas without passing through a liquid phase.

This water vapor is then removed by the vacuum system. What remains is beef liver with only about 1–5% moisture content.

With minimal heating or chemical alteration, freeze drying beef liver preserves more of its natural nutritional content compared to other methods like cooking, smoking or air drying.

Step-by-Step Instructions for Freeze Drying Beef Liver at Home

With just a few simple steps you can easily make crunchy, shelf-stable homemade dog treats using beef liver.

What You Need

• Beef liver (chicken livers or other organ meats work too)
• Baking sheet lined with parchment paper
• Sharp knife
• Cutting board
• Plastic wrap
• Freezer
• Airtight container for storage

Step 1 – Prepare the Beef Liver

Rinse liver under cool water and pat dry with paper towels. Trim off any membranes or discolored parts. Slice liver into thin, uniform pieces about 1⁄4 inch thick so they freeze and dry evenly.

Step 2 – Arrange on Baking Sheet

Place liver slices in a single layer on the parchment paper, leaving space between each piece. Cover with plastic wrap pressed directly against the surface of the liver. This prevents freezer burn which can cause drying and texture issues.

Step 3 – Freeze Liver

Put baking sheet in freezer overnight or for at least 12 hours until liver is completely frozen solid. Duration depends on freezer temperature.

Step 4 – Remove Plastic Wrap

Once fully frozen, take liver out of freezer. Remove and discard the plastic wrap. Place back in freezer uncovered. This allows moisture to evaporate from the liver as it freeze dries.

Step 5 – Check Liver and Remove Moisture

After several hours, remove tray and inspect liver. It will appear darker, shrunken and dried out once the moisture has sublimated out. Blot any droplets of water from the parchment paper using paper towels.

Step 6 – Continue Drying

Put liver back in freezer for 8-12 hours more. Repeat checking and blotting moisture every several hours until the pieces are completely hard and dry with no ice crystals remaining. This can take 24-48 hours total.

Step 7 – Store Freeze Dried Liver

When fully dry, break liver into bite-sized pieces. Place pieces in an airtight container or plastic bag. Store in fridge for 2-3 weeks or in freezer for several months.

And that’s all you need for homemade treats with the nutritional benefits of beef liver that dogs love!

Tips for Customizing Your Homemade Liver Dog Treats

Once you’ve mastered the basic freeze drying process, get creative with these ideas for custom treats:

• Shape liver into discs or fun shapes using cookie cutters before drying
• Mix in other ingredients like vegetable broth, pureed sweet potato or pumpkin before drying
• Add sprinkle of spices like cinnamon, turmeric or ginger for flavor variety
• Use different animal livers like chicken, pork or lamb liver
• Swap in or combine organ meats like kidneys, tripe, heart or gizzard
• Dry thin liver slices faster than thicker pieces for training treats with more texture

Experiment to come up with your pup’s new favorite flavors and use small batches to test reactions before making big batches.

Storing and Handling Freeze Dried Liver Safely

It’s important to take steps to avoid any potential health risks when making and storing dried liver:

• Always source high quality, fresh liver from reputable suppliers
• Keep raw liver and treats separate from other dog food to prevent contamination
• Wash hands, utensils and surfaces thoroughly after handling raw liver
• Defrost treats in fridge when taking out of freezer to prevent condensation
• Discard any treats with changes in texture, smell or appearance or past expiration date
• Store treats in sealed container in fridge no more than 2-3 weeks, or freezer up to 8-10 months

Feeding Guidelines for Freeze Dried Liver Treats

Beef liver is very rich, so limit intake to avoid gastrointestinal upset:

• Give treats in moderation, not whole meals
• Aim for liver to make up no more than 5% of your dog’s total daily calories
• Start with giving treats in small amounts and gradually increase as tolerated
• Adjust portion sizes for your dog’s size – small breeds need less than big dogs
• Supervise your dog with treats and stop feeding if any diarrhea or vomiting occurs
