No bones about it: the scoop on bone broth for dogs

Note: this article is a long read, but if you scroll to the very end, there is a quick summary explaining which dogs would benefit the most from bone broth!


Bone broth for dogs has been gaining popularity lately, following claims that it is a nutrient dense “superfood” that can help improve your dog’s immune system and joint health, among other things. Let’s take a more in depth look into some of these claims and analyze the potential benefits that bone broth may provide for our dogs.

But first, what is it? The name is pretty self explanatory – it is a broth made with bones (although, technically, stock would be the correct term). Fill your pressure cooker with bones, water, and vinegar (or lemon juice). It is recommended to let it cook for anywhere from 8 hours to 24 hours or even a couple days. Ta-da, you have bone broth! Many people then freeze the broth into ice cube trays for more convenient daily feeding.

Why should you make bone broth for your dog? There are plenty of articles that speak of the wonders of bone broth, claiming that it is packed with tons of vitamins and minerals, it does wonders for joint health, and it can even help “detox” your dog’s liver! But is this all true, or is bone broth just the newest “miracle cure-all” fad?

Before you dive in and make your whole house stink of bone broth, let’s do some fact checking.


Claim: bone broth is packed with nutrients.
Conclusion: MYTH

This is one of the most common reasons why bone broth is recommended. It is said that the vinegar “leeches” the nutrients from the bones while the broth is cooked, resulting in a broth packed with mangesium, phosphorus, sodium, potassium, and especially calcium. On the surface, this makes sense, because any raw feeder knows that bone is a great source of calcium.

But unfortunately, a nutrient analysis of bone broth shows that this isn’t the case [source]. In the nutrient analysis linked in the previous source, they even used white vinegar, which is more acidic than the typically recommended apple cider vinegar. So why didn’t the vinegar leech the nutrients out of the bones as expected? To explain why this might be happening, let’s take a trip back to our high school chemistry class.

Remember the periodic table? Calcium, magnesium, sodium, potassium… these are all chemical elements. These elements are all cations or anions, meaning they all have an ionic charge, which allows them to form or break chemical bonds with other elements or compounds. This is called a chemical reaction. When you make bone broth, these chemical reactions are happening inside your pressure cooker.

Claiming that the acidic vinegar will leech the calcium and other minerals into the water is overly simplistic. In theory, it could happen, but in practice, it doesn’t – and it can probably be explained by the chemical composition of bone itself. Bone is composed of a compound called hydroxyapatite with a couple different ions that really like to form compounds with each other – think of them like magnets that are attracted to each other. There are only so many of these individual ions that can remain in the solution before they start to react with others to form different compounds. The compounds that are most likely forming aren’t soluable enough to dissolve in the broth. For that reason, many of these compounds will not remain suspended in the liquid – most of them will form a solid precipitate at the bottom of the solution [source].

In other words, there is a limit to the amount of minerals that remain suspended in the liquid, and any minerals beyond that limit will instead be in the leftover bone sediment at the bottom of the broth. As a result, not only is the bone broth liquid not nutrient dense, but it turns out it is actually a very poor source of nutrients.

In the case of calcium, you might actually end up with less calcium in the bone broth liquid than were in the water that you started with [source]. This means that there might actually be more calcium in a glass of well water than a glass of bone broth! The only minerals that seem to remain in liquid bone broth at significant levels are potassium and sodium, and even then, other foods would be a much better source.

As for the sediment at the bottom: it will contain a decent source of minerals, but it still falls far short of raw bone.

For this reason, bone broth is not an appropriate substitute for bone content in a raw diet.

Adding veggies to the bone broth or even just making broth with all veggies actually increases the amount of minerals that are able to remain in the broth, likely due to the more soluable chemical composition of plant matter in comparison to bone. So as it turns out, if you want a more mineral rich broth, you should make it with veggies instead! Or, if you want to add something to your dog’s diet that is mineral rich, supplementing with raw foods would be much better than bone broth.


Claim: the collagen in bone broth gelatin helps improve bone and joint health.
Conclusion: HALF-TRUTH

Although bone broth might not contain very many minerals, it does contain a lot of protein! And naturally, most of that protein is collagen, the structural protein that connects and holds together an animal’s bones, tendons, ligaments, cartilage, and skin. This collagen is found in the gelatin that forms at the top of the bone broth. Gelatin is a very good source of collagen [source].

Collagen, like all protein, is made of amino acids. Amino acids are incredibly important; they play a part in virtually all cellular processes within the body. Ten amino acids are considered essential for dogs [source], meaning that must obtain them from their diet. The rest of the amino acids can be synthesized by the body, so they are considered non-essential and aren’t required to be obtained by the diet.

When a protein is digested – regardless of what kind of protein it is – it is broken down into these amino acids, which are then used by the body wherever they are needed most at the time of digestion. So, technically, it isn’t as simple as “eat collagen, improve joint health” just because collagen is involved in the structure of joints. Similar to how consuming fat in the diet doesn’t directly translate to fat in the body – it is a bit more complex than that.

“The idea that because bone broth or stock contains collagen it somehow translates to collagen in the body is nonsensical.”

– Dr. William H. Percy, associate professor and biomedical scientist, University of South Dakota [source]

Collagen is a great source of the non-essential amino acids glycine, alanine, and proline, but a very poor source of some essential amino acids like lysine, leusine, or histidine [source]. Raw or cooked beef is a far better source of essential amino acids than collagen [source].

You might be getting discouraged about bone broth’s ability to be beneficial to your dog’s health… but don’t stop reading yet! Just because bone broth isn’t a good source of essential amino acids doesn’t mean it isn’t beneficial. Your dog should already be getting all of his essential amino acids from his diet already anyway (and if he isn’t, then you have a lot more to worry about than bone broth)! Supplementing the diet with non-essential amino acids may be beneficial.

Studies show that supplementing the diet with collagen may help improve symptoms in dogs with arthritis [source, source]. Gelatin could have the same benefits due to its high glycine content [source]. Glycine is not considered an essential amino acid, but a couple studies have shown that the amount of glycine able to be synthesized by the body may not be enough to satisfy all metabolic processes alone, suggesting that more glycine must be obtained from the diet [source]. One of the metabolic processes that would benefit from more dietary glycine is collagen synthesis.

Bone broth isn’t the only source of glycine, of course; pork, lamb, and beef are also very high in this amino acid. But gelatin is one of the best sources of glycine [source].

“This result supports earlier suggestions in the literature that glycine is a semi-essential amino acid and that it should be taken as a nutritional supplement to guarantee a healthy metabolism.”

– Study: A weak link in metabolism: the metabolic capacity for glycine biosynthesis does not satisfy the need for collagen synthesis. [source]

Long story short… yes, bone broth gelatin could be beneficial for your dog’s joint health!

But remember, we’re talking about the gelatin in bone broth here, not just the liquid. There isn’t much evidence suggesting that liquid bone broth has the same benefits.

Worth noting: raw fed dogs that get enough red meat in their diet are already consuming far more dietary glycine than kibble fed dogs, so it probably isn’t completely necessary to give bone broth to a raw fed dog – but, of course, it won’t hurt either. Kibble fed dogs, on the other hand, would benefit even more from the extra amino acids that may be lacking in their diet, because heat processing denatures many of these amino acids (and bone broth would add more dietary moisture, too, which is an extra plus for kibble fed dogs).


Claim: bone broth can “detox” your dog’s liver.
Conclusion: MYTH

Well, first of all, one of the liver’s main functions is to detoxify chemicals and metabolize drugs in the body. If your dog’s liver isn’t doing that already, it isn’t functioning correctly, and that is a serious health condition that bone broth, or any other supplement or diet claiming to “detox” your dog’s body, can’t fix [source]. Improper liver function is something to discuss with your vet. If your dog’s liver is working correctly, then it doesn’t need to be “detoxed” – it is literally already doing that itself.

While some studies have shown that the amino acid glycine found in bone broth may help improve liver function [source, source], it could also be potentially dangerous to give bone broth to a dog with liver disease.

Keep in mind that the studies linked as sources are using a glycine supplement, not bone broth itself. Furthermore, also keep in mind that many of the studies researching the benefits of collagen are also not using bone broth – they are using a hydrolyzed collagen supplement. Hydrolyzed collagen is much easier to digest than gelatin because the amino acid bonds are already broken down. With bone broth gelatin, the liver would still have to break down the collagen proteins in order to utilize the amino acids.

Giving a high protein supplement, such as bone broth, to a dog with severe liver disease may do more harm than good.

A diseased liver may not be able to properly break down those extra proteins, putting more strain on the liver. It then may not be able to get rid of waste products, resulting in a build up of ammonia in the bloodstream. This can cause severe health complications in the central nervous system, eventually resulting in hepatic encephalopathy: the loss of brain function due to the build up of toxins in the blood and brain.

Of course, that is an extreme example of what could happen in a very severe situation. But the point you should take away from this is that there aren’t very many studies proving many of these claims about bone broth specifically. Just because an amino acid that can be found in bone broth has certain benefits, doesn’t mean that directly translates to bone broth having those benefits. In many cases, it is not that simple. For this reason, I would recommend speaking to your vet before giving your dog bone broth if he has liver disease.

For dogs with normal liver function, there is no harm in giving bone broth – and although it hasn’t been explicitly proven, bone broth very well may help support liver health.


In conclusion…

Bone broth does have its uses, and there is evidence to support the idea that it could be beneficial. However, keep in mind that if something sounds too good to be true, it probably is. Many of the claims about bone broth are exaggerated or oversimplified half-truths.

When you weigh the risks vs. benefits, bone broth comes with very little risk, and the potential to be beneficial. For that reason, bone broth would be a good choice to add to your dog’s diet – but don’t rely on it alone to solve your dog’s health issues.

So to answer the question,

Should I feed my dog bone broth?

The dogs that could benefit the most from bone broth are…

  • Kibble fed dogs
    • Why? During the high heat processing of kibble, a significant amount of amino acids are lost due to denaturation [source]. Essential amino acids will be supplemented in order to meet minimum nutrient requirements if necessary, but non-essential amino acids typically will not be, since there is not a minimum requirement that pet food companies must meet. But since obtaining non-essential amino acids in the diet has been shown to be beneficial, I would recommend feeding kibble fed dogs bone broth to help make up for the amino acids that their diet is lacking. Bone broth also adds a source of moisture to kibble, which is beneficial to general health and can help prevent issues such as urinary stones or UTIs [source].
  • Dogs with joint issues or skeletal injuries
    • Why? Supplementing the diet with bone broth gelatin could help provide the body with more dietary “conditionally essential” amino acids that are involved in collagen synthesis and healing processes [source].
  • Picky, sick, or dehydrated dogs, and/or dogs with a suppressed appetite
    • Why? Bone broth is said to be very palatable, so adding it to the diet may encourage the dog to eat. The same goes for dehydrated dogs – adding bone broth to water may encourage them to drink more. However, keep in mind that bone broth is not an adequate source of vitamins, minerals, or essential amino acids, so you should NOT rely on bone broth alone to provide nutrition to a sick dog! 


When should you NOT feed bone broth?

  • Dogs with severe liver disease
    • Why? Although bone broth may be beneficial in theory, it could potentially just put more strain on the liver since it still has to be broken down. I think it would be safe to say that bone broth most likely would not cause issues in a dog with liver disease, but in this case, I would rather be safe than sorry.  It would be safer to supplement the diet with something that takes as little effort as possible to digest and utilize, such as an amino acid supplement or hydrolyzed gelatin.

  1. Thanks for the suggestion Marnie. I tried Buster’s Brew and my dogs really enjoy it. I’ll be recommending it to others.

  2. My husband and I drink bone broth instead of coffee in the morning. We used to take 2 days to make it on the stove. Then we got an Instant Pot. 8 qts of broth done in 4 hours. The dogs love it and since they eat raw, we only give it as a treat. Like when they come in from being outside on a frigid day. (they are seniors). But we all enjoy it and it helps with my husbands aches when he has worked outside. (we are seniors too!).

  3. I used to cook bone broth for my dogs and cats, but it’s still time consuming and messy. Recently started buying a product called Busters Brew – and my dogs love it. It’s a bone broth tea with other ingredients to make it more nutritious.

  4. Hi Plear, I really appreciate your thorough review of bone broth, especially coming from a raw foodist with science knowledge. I’d also like to point out something I read in another article, that “bone broth” is just “stock”, and was in fact something that people with no better options cooked with the scraps they could afford for food. The fact that it happens to be easy on the digestive system, and great as a soup base are bonuses. Thanks!

  5. I used to make broth but it takes so long. Recently bought a couple of brands to try and my dog seems to love the bone broth tea I get from

  6. We love our bone broth – especially since we get a lot of free weight bearing bones from our local farmers. Cut them up, toss in the crockpot and simmer for 2 days – voila! I love keeping bone broth on hand for my kiddos since it keeps them well hydrated. I dilute a spoonful into a 3/4cup of water 3x a day when we are in high summer (hot hot hot) and in the cold, dry winter. It’s just a bonus that it has some added benefits. I call it their “tea” since that’s what I view it as. Tea has antioxidants and great health benefits, but isn’t a silver bullet. It’s a great way to get them extra water, and use up those bones so they don’t go to waste.

  7. I love this article. So true. Bone broth for dogs contains so many great benefits for dogs. Preparing it and cooking it is the only issue as it takes hours to make over the stove.

  8. I have tried giving bone broth to my dog when she got sick after reading articles regarding its benefits. Au Bon Broth has been helping her regain her health and energy.
