How to Feed Raw Kidneys for Dogs & Puppies

Table of Contents

Kidney doesn’t get nearly as much attention as liver in raw feeding, but skip it and you’re missing half of your dog’s secreting organ requirement – kidney and liver split that 5%/5% share right down the middle.

It’s a smaller, quieter piece of the raw feeding puzzle, but it’s the one most closely tied to supporting your dog’s own kidney health.

I’m Barbara, and I’ve been feeding my dogs raw since 2015 – first in the US, and now here in Germany, where I also work for one of the country’s leading raw dog food brands, BARFER’S.

Below, I’m covering exactly how much kidney to feed adult dogs and puppies, where to source it, and what to do if your dog’s dealing with kidney disease.

That said, here’s what you’ll learn in this blog post:

Feeding Raw Kidneys for Dogs & Puppies

How to feed raw kidneys for dogs and puppies

What’s in Raw Kidneys?

Similar to other secreting organs, raw kidneys are highly nutritious and known as a natural multivitamin.

Here’s what’s in raw (beef) kidney:

Vitamin A (specifically Retinol)
B Vitamins (Thiamin aka B1, Riboflavin aka B2, Niacin aka B3, Pantothenic Acid aka B5, B6, Folate aka B9, B12)
Vitamin C (very little)
Vitamin D (very little)
Copper
Iron
Magnesium (very little)
Manganese (very little)
Phosphorus
Potassium
Selenium
Sodium
Zinc

That said, kidneys are richest in Retinol (Vitamin A), Vitamins B1, B2 and B12, Selenium, Copper and Iron.

Which brings me to the next question:

Why Are Raw Kidneys Good for Dogs?

Kidneys are richest in the following vitamins and minerals:

Vitamin A (Retinol): Supports cell growth & divisions for healthy eyes, skin, coat, nervous system, muscles, reproduction and the immune system
Vitamin B1 (Thiamin): Helps digest carbs & supports brain function
Vitamin B2 (Riboflavin): Supports the metabolism of fats & carbs into energy and supports the production of red blood cells
Vitamin B12: Supports the blood flow and the nervous system as well as the brain and digestive functions
Selenium: Supports a healthy thyroid and is important for reproduction
Copper: Helps make red blood cells, skin cells, connective tissue and absorbs iron
Iron: Supports normal formation of red blood cells

Where Do Kidneys Fall Into the 70/10/10/10 Raw Feeding Formula?

Kidneys fall into one of the 10s!

More specifically, into the secreting organs 10s.

As a quick recap for anyone new to raw feeding, here’s what the 70/10/10/10 formula stands for:

Muscle Meat (70%)
Raw Meaty Bones (10%)
Secreting Organs (10%)
Plant Matter (10%)

Secreting organs are split up into 5% liver and 5% other secreting organs.

And so yep, you guessed it, kidney is part of the 5% other secreting organs.

That said, dogs require very little secreting organs in their daily meals, but you also can’t skip them. At least not on a regular basis.

Let me put it like this: It’s perfectly fine to achieve balance in raw feeding over the course of several days to a week.

So if you forget to add secreting organs to your pup’s meals on 2 or 3 days out of the week, don’t stress out over it. Just don’t make it a habit!

It’s a myth propagated by the pet food industry that dogs (and cats) need specific nutrients on a DAILY basis.

After all, no single animal in the wild eats 100% balanced food on a daily basis.

Neither do we, right?

So yes, I like to follow a common sense approach as far as raw feeding is concerned. I don’t appreciate nor fall for the scare tactics of the dog food industry and traditional veterinarians.

I mean, their education includes very limited nutritional knowledge because they’re sponsored by big name kibble dog food brands.

OK, rant over! Moving on to the next question:

How Much Raw Kidney Should I Feed My Dog?

Next, let’s talk about how much kidney to feed your dog. This is going to depend on your respective dog, and mostly on their age and activity level.

I’ll give you 3 examples for adult dogs, and 3 examples for puppies.

As we just covered, kidneys are fed alongside liver.

Each secreting organ (kidney and liver) makes up 5% of your adult dog’s daily raw dog food allowance.

Puppies need 7% of each secreting organ, but more on that in the puppy feeding example section.

How much raw kidney should I feed my dog?

How Much Raw Kidney to Feed Adult Dogs: 3 Feeding Examples

Here’s how you do the math:

Divide your dog’s target/ideal body weight by 100, then multiply with your dog’s maintenance percentage.

That’s 2.5% on average. The result is your adult dog’s daily raw dog food allowance.

Note: Canine athletes and pregnant dogs will need considerably more raw dog food, up to 4% of their target body weight.

That makes sense when you think about it because their energy requirements are a lot higher than those of “regular” pets.

Example 1: 28lb Adult Dog

28/100 = 0.28 x 2.5 = 0.7lb = 11.2oz

11.2oz is your dog’s daily raw dog food allowance. Here’s how it’s split up into the different raw dog food components:

7.84oz muscle meat
1.2oz raw meaty bone
0.6oz liver
0.6oz kidney
1.2oz plant matter

Example 2: 45lb Adult Dog

45/100 = 0.45 x 2.5 = 1.125lb = 18oz

18oz is your dog’s daily raw dog food allowance. Here’s how it’s split up into the different raw dog food components:

12.6oz muscle meat
1.8oz raw meaty bone
0.9oz liver
0.9oz kidney
1.8oz plant matter

Example 3: 74lb Adult Dog

74/100 = 0.74 x 2.5 = 1.85lb = 29.6oz

29.6oz is your dog’s daily raw dog food allowance. Here’s how it’s split up into the different raw dog food components:

20.72oz muscle meat
2.96oz raw meaty bone
1.48oz liver
1.48oz kidney
2.96oz plant matter

How Much Raw Kidney to Feed Puppies: 3 Feeding Examples

Puppies require more food than average adult dogs because they’re still growing, specifically:

58% muscle meat
17% raw meaty bones
14% secreting organs
11% plant matter

If you’re feeding your puppy following the prey model approach, scratch the 11% plant matter and feed 69% muscle meat instead.

You can either feed them a certain percentage of their current body weight, or feed them 2.5% of their target adult body weight.

I find the second approach more difficult to gage though, so I prefer calculating their allowance off of their current body weight.

Obviously, you’ll need to weigh your puppy regularly, at least every month, but I’d do it even more frequently than that, say every 2 weeks.

Here are 3 options to weigh your puppy:

Ask your vet if you can come in to weigh your puppy every other week.
Once your pup’s had all their puppy shots, you can also take them to a pet retail store and weigh them there. Most stores that offer grooming services also have a pet scale.
Of course you can also weigh your puppy at home with your own body weight scale or a specific digital pet scale.

Example 1: 4 Month Old Boxer Puppy Weighs 30lbs. Feed 8% of Their Current Body Weight

Remember, puppies need different amounts of raw dog food cuts than the average adult dog:

58% muscle meat
17% raw meaty bones
14% secreting organs
11% plant matter

Here’s how to do the math: Divide your puppy’s current body weight by 100, then multiply with 8. The result is your puppy’s daily raw dog food allowance.

30/100 = 0.3 x 8 = 2.4lb = 38.4oz

38.4oz is your puppy’s daily raw dog food allowance. Here’s how it’s split up into the different raw dog food components:

22.272oz muscle meat (round up to 22.3oz)
6.528oz raw meaty bones (round down to 6.5oz)
2.688oz liver (round up to 2.7oz)
2.688oz kidney (round up to 2.7oz)
4.224oz plant matter (round down to 4.2)

Example 2: 6 Month Old Standard Poodle Puppy Weighs 50lbs. Feed 6% of Their Current Body Weight

50/100 = 0.5 x 6 = 3lb = 48oz

48oz is your puppy’s daily raw dog food allowance. Here’s how it’s split up into the different raw dog food components:

27.84oz muscle meat (round up to 27.9oz)
8.16oz raw meaty bones (round up to 8.2oz)
3.36oz liver (round up to 3.4oz)
3.36oz kidney (round up to 3.4oz)
5.28oz plant matter (round up to 5.3oz)

Example 3: 8 Month Old German Shepherd Puppy Weighs 65lbs. Feed 4% of Their Current Body Weight

65/100 = 0.65 x 4 = 2.6lbs = 41.6oz

41.6 oz is your puppy’s daily raw dog food allowance. Here’s how it’s split up into the different raw dog food components:

24.128oz muscle meat (round up to 24.2oz)
7.072oz raw meaty bones (round up to 7.1oz)
2.912oz liver (round up to 3oz)
2.912oz kidney (round up to 3oz)
4.576oz plant matter (round up to 3.6oz)

Where to Buy Raw Kidneys for Dogs

Unlike chicken, beef and even calf liver that you can buy in almost every grocery store, it’s a lot harder to find kidneys.

You’ll have to either revert to butchers or farmers, specialty stores such as asian grocery stores, wildlife processors during hunting season, or raw dog food retailers:

Butchers or farmers
Asian grocery stores
Wildlife processors
Raw Paws Pet Food
Raw Feeding Miami
My Pet Carnivore
BJs Raw Pet Food

Of course it’s a different story if you hunt yourself or know someone who hunts. Just keep the (secreting) organs such as liver or kidneys for your dog, or ask if you can have them.

You can learn more about deer hunting for raw dog food meal prep here.

Pictured below is raw deer kidney from a freshly shot buck (thanks bf!).

Always try to feed kidneys from a large variety of animals. For example, beef kidney, rabbit kidney, goat kidney, lamb kidney, etc.

Also know that while kidney is a secreting organ and falls into the 5% other secreting organ category to be fed alongside liver, it’s important to rotate the other secreting organs.

If you want, you can create meals that consist of 5% liver, 2.5% kidney and 2.5% pancreas.

Or, 5% liver, 2.5% brains and 2.5% spleen.

Another option is to rotate the other secreting organs on a weekly, bi-weekly or monthly basis.

Essentially, whenever you make a batch of raw meals, add a different secreting organ. That’s easier in my personal opinion.

Or, you can also switch it up between the two options.

Honestly, do whatever works for YOU as long as you provide variety!

Where to Buy Kidney Disease Supplements for Dogs

If your dog is diagnosed with kidney disease, another option besides feeding raw kidneys is to offer kidney supplements for dogs such as:

Also, Omega-3 fatty acids (EPA & DHA) for antioxidants. This can be oi l y raw fish or high-quality fish oils like:

Planowpaws Wild Omega-3 Fish Oil (made from sardines, herring and mackerel)
Fera Pets Fish Oil (made from sardines, anchovies, mackerel and herring)

Here’s a great video by Dr. Judy Morgan on how to treat kidney disease in dogs.

Feeding Raw Kidneys for Dogs: Bottom Line

So, as you just saw, knowing how much of what to feed is essential in raw feeding. That also applies to kidneys!

Keep in mind that dogs don’t need a lot of kidney in their daily raw dog food allowance.

Also, the exact amount differs between dogs and their respective nutritional needs.

Growing puppies, pregnant dogs and canine athletes are going to need more kidney than adult pet dogs.

Don’t forget to offer your dog(s) a variety of secreting organ meats and to have FUN when sourcing ingredients and preparing their raw meals!
