Leaky gut, also called intestinal permeability, may affect more than your dog or cat’s digestion. In this video, Dr. Andrew Jones explains what leaky gut is, the signs to watch for, common causes, testing options, and natural ways to support gut repair.
Possible signs include diarrhea, vomiting, bloating, nausea, soft stools, acid reflux, skin allergies, low energy, and other chronic inflammatory problems. Dr. Jones also discusses factors that may damage the intestinal lining, including highly processed food, antibiotics, corticosteroids, parasites, stress, and environmental toxins.
You’ll also learn about newer testing options that look at markers linked with intestinal permeability, including zonulin and anti-gliadin IgA. These tests are not considered definitive, but they may provide useful clues when chronic digestive problems continue.
For support, Dr. Jones starts with diet: more fresh, minimally processed food and gut-friendly additions such as pumpkin and blueberries. He also covers probiotics, Saccharomyces boulardii, psyllium husk, slippery elm, colostrum, collagen, L-glutamine, and zinc carnosine.
If your dog or cat has ongoing digestive issues, allergies, or unexplained inflammation, this video explains practical options for supporting the gut and helping restore a healthier intestinal barrier.
The goal is simple: calm inflammation, support healthy bacteria, and strengthen the intestinal lining.
Your dog or cat could have this condition called leaky gut which can cause so much just more than
GIT health problems. It can cause skin disease, immune dysfunction, chronic fatigue. In today's
video I'm going to show you exactly what this is, the underlying causes, how you can tell if your
dog or cat has it, plus my top holistic options that can really help. Are you looking to learn

Another condition? Like another disease? Leaky gut? Like is that even a thing? Well when I was
practicing as a veterinarian and someone said I think my dog or cat has leaky gut I would be like
okay this is just another one of those like potential diseases. We might call them functional.
There is no real diagnostic test for it. Like does it even exist? Even though most conventional
veterinarians they're not even going to test for this. The research now is showing that yeah this
really is a serious health concern. Something you should be aware of. To be more specific if you
want to sound more technical let's call it intestinal permeability. So what is a leaky gut?
Well think about your intestines, your cat or your dogs. So imagine this is the intestine.
It's made up of all these cells, intestinal cells. The intestinal cells that are lining the inside of
this intestinal tract as you can see here and their job is to number one they're going to
absorb certain nutrients. We're going to allow certain things in, keep certain things out.
All right so if you can imagine there's this tightly woven like millions of cells lining the
inside of the tube and they're held quite close together. Think about like it as a type of glue.
So in leaky gut or intestinal permeability what's happening is now your dog is eating
or consuming certain amounts of food partly broken down in the stomach makes its way into
the intestinal tract and what's happening is certain things such as large proteins
maybe other toxins maybe your dog ate a bunch of garbage ate some compost maybe include a fungal
toxin that should stay out of the blood system. But if there's a breakdown in that glue layer
all of a sudden intestinal cells aren't tight together it's allowing some of that stuff in
these large proteins right some of these potential toxins your animals consume are just things that
they get through their food or just what's happening as they walk around the lawn and
they're licking their paws consuming a roundup right. Some of that stuff can make its way within
the blood system causing a whole host of reactions. Here's my little graphic example
intestine a bit of fluid look it's staying there it's not leaking out that's what should be
happening. Now imagine this is the intestines of a dog or cat with leaky gut so what happens
they're consuming that food so maybe some of that compost and look what's coming out of the
center of the intestinal tract yes fluid it's leaking. So then what's happening is toxins
undigested food particles they're now getting into the blood system and they shouldn't be.
So as those particles get absorbed as they leak through the gut then what goes on within your
dog or cat well the immune system it's going to react right all of a sudden you see all these
foreign things entering the blood system and the immune system is like recognizing it this is
abnormal we got to deal with it these big protein particles from undigested food. Now some of the
foodborne toxins allergens even bacteria that shouldn't be present now within your pet's
bloodstream. So typically yes you'd expect some gastrointestinal signs diarrhea vomiting maybe
bloating distention maybe just upset stomach your dog or cat might kind of walk after eating just
a little bit tenderly you may even see acid reflux sometimes excessively loud stomach noises you
might have a dog or cat that just kind of intermittent bouts of nausea and maybe just
sort of poorly digested food maybe it's soft stools but the even bigger concern is yes we
can recognize the gastrointestinal issues but not every dog or cat that is going to have leaky gut
is going to have overt chronic gastrointestinal issues and all likelihood you've seen your
veterinarian you probably got some form of treatment going on maybe you've got your dog
or cat on a specific diet maybe you're using intermittent antidiarrheals just to manage this
maybe they've been on a drug like metronidazole but what's happening is as some of those particles
some of those allergens some of the bacteria they're entering the blood system they can trigger
a whole host of chronic inflammatory diseases. Inflammatory skin disease i.e. are animals with
allergies. Inflammatory arthritis right you've got these animals which are chronically or
intermittently lame. Organ dysfunctions such as liver disease kidney disease now there's clear
links in people with leaky gut and cardiovascular disease right there's direct correlations with
leaky gut and diabetes right because all of a sudden we've got inflammation that could be
targeting the pancreas pancreas can't produce enough insulin and or targeting the cells of the
body making them less responsive to insulin hence our animals and many people with type 2 diabetes
and believe it or not there's even a direct correlation with chronic fatigue syndrome
and we're seeing this in some of our dogs and cats it's kind of an animal where in veterinary
practice we would call them ADR which means ain't doing right in terms of they just they
they're lethargic they don't have enough energy they're just you know they're just not a hundred
percent but blood work might show like nothing remarkable maybe they've been worked up you can't
explain why but they just are chronically weak unfortunately there isn't yet a gold standard
test that you can run in veterinary practice and yeah a hundred percent my dog or cat has leaky
and in fact because it's considered a functional disease not a real disease right many veterinarians
aren't even considering it or testing for it fortunately now there are a few companies which
are testing for this and there's a couple of specific markers and that these companies are
using and trying to measure is this out of range or not the company that we're working with is
and they actually have a couple of specific diagnostic tests focusing on leaky gut they're
testing for one one of the markers they test with it's called zonulin so zonulin acts like the glue
so this little hole that happened in my sample intestine wouldn't be there right it's sort of
gluing the cells together so you don't have this intestinal permeability so they're able to test
for zonulin second they can test for an antibody to gluten called anti-gliadin iga and this is
another marker that is often elevated if we're going to have animals that have leaky gut or
intestinal permeability now these aren't considered definitive diagnostic tests in terms of okay this
marker here 100 confirms your dog or cat has leaky gut but it gives you a strong indication that that
may be the case unfortunately now with innovative pet lab you don't need to order this through your
veterinarian we're going to put a link in the description box you can get a specific home
test kit and get these tests done yourself at home the big question comes to like what is causing
leaky gut like why are we seeing so many animals that potentially have gastrointestinal disease
secondary chronic inflammatory disease which in many cases be caused by leaky gut like what's
going on but first and foremost it goes to diet right highly processed food like the kibble
right highly highly processed exposed to high high heat it produces compound count ages or advanced
glycation end products and we know that that can be directly toxic to intestinal cells right and
that can be a direct trigger for leaky gut but there's more right nzads non-steroidal
anti-inflammatory drugs they can damage the intestinal tract leading to leaky gut corticosteroids
like prednisone they can damage the intestinal tract leading to leaky gut what else oh we have
antibiotics right can alter the gut microflora can lead to serious inflammation within in the
intestinal tract leading to leaky gut untreated intestinal parasites can damage the gut leading
to leaky gut stress environmental toxins which we just talked about right our animals are exposed
to so many more than us right they're down though they're walking in the grass they lick their paws
right or even just what's within our house we have things like house dust contaminated with
some of these forever chemicals right companies thought it was really wise if we make things like
couches we infuse them with fire retardant chemicals seems great they won't burn but these
are considered some of these pretty toxic forever chemicals they leach out into the house dust your
dog and cat walks around they groom themselves they ingest these chemicals and that can damage
the gut so aren't i the bear of unhappy news okay there are some good things first if you have a
cat that's pretty healthy you may want to think about a diet change if your dog or cat is eating
this the highly processed kibble you sure don't want to have an animal with leaky gut secondarily
when i look at the number of animals that have chronic inflammatory disease i mean just think
about the number of dogs that have allergies right or think about the incidence of the number of cats
we're seeing with you know type 2 diabetes chronic vomiting chronic gastrointestinal disease
many many many of our animals have had so much of their gut you know being exposed to all these
different things the same environmental toxins we're exposed to and of course their intestines
are going to get damaged which makes me think in many cases i probably should have put some
more thought into you know some of these chronic inflammatory diseases we can't explain right we're
using something like april quill to treat our dog's allergies and yeah maybe we've tried you
know maybe just one specific hydrolyzed protein dog food but maybe we should have looked at also
addressing you know the core issue like what's caught what's causing or cause that in the first
place like healing their gut secondarily to maybe then get them off the april quill right but that
is seldom discussed so here's some specific action steps you can take now whether or not
your dog has a condition at the very least help preventing from ever happening to them
so number one we're starting with diet less to none of this ideally right if you can if you can
switch the partial partially of your dog your cat's diet to be like less processed right here's a
gently cooked pre-packaged minimal process dog food so you're not exposing it to high heat
you've got real ingredients that you can recognize where it's been thrown into a giant
batch of everything and mixed up bazillion times exposed to high high high heat and pressure
so it can form and be excreted in the shape of a kibble right because when you make food this way
you have less ages you retain so many of the good positive nutrients it can have medicinal
offer medicinal benefits it's going to include some of the good flavonoids some of the polyphenols
things that can decrease gut inflammation decreasing the likelihood of leaky gut
so like as much as it can fresh whole unprocessed food number two just consider adding things even
if your dog is still on cable your cats help your cat should not be on any dry food but if your cat
still eating conventional food adding in additional nutrients can help right so think about
things that are whole minimal to unprocessed that can decrease gut inflammation things like squash
canned pumpkin is great for our dogs and cats sweet potato here right is a really good option
in terms of a slower releasing carbohydrate that's got some great um flavonoids in it
that can potentially help decrease gut inflammation even as some of this is added you know partly
once or twice a week a really inexpensive hack of all the ones i just talked about
good for our dogs good for our cats this is liver really rich in protein really rich in iron
rich in a number of different vitamins and minerals and it's rich in some of the medicinal
nutrients which can not only offer health benefits your dogs and cat a bunch of different diseases
specifically eating the gut decreasing gut inflammation and that's our goal here to
provide nutrients that they're going to lower gut inflammation not further damage the intestinal
lining making it more difficult for the intestines to work increasing the chance of leaky gut
developing and fyi if you're going to use organ meat you know i typically say you're two to three
times a week although with some people who are making their dog or cat food at home there are
going to include organ meat daily but if you're sort of topping it up with a commercial diet
two or three times a week and cassian over here he loves his liver and i just give him a tablespoon
yeah two or three times a week number three consider a good probiotic supplement such as
dr jones's ultimate probiotic formula regardless of the underlying cause the majority of time
when there is inflammation within the gut there's leaky gut we have an altered my gut microbiome
meaning the good bacteria are no longer present so you want to ensure that you have a good
probiotic supplement includes a wide range of gut bacteria some of the lactobacillus species
strep thermophilus along with a prebiotic which ours includes a fructooligosaccharide
we need the prebiotic there so the good bacteria can grow saccharomyces velarde there is another
probiotic it's actually a type of yeast called saccharomyces and for whatever reason many of
animals with leaky gut seem to respond positively to it right so if you've tried some of the
probiotic supplements without saccharomyces you haven't seen an improvement i would actually
encourage you to try saccharomyces you know looking at minimum doses 1 billion cfus
per 10 to 20 pounds of body weight daily there are some newer and emerging remedies specifically for
leaky gut and some of our animals respond really well to them and some of them are surprisingly
quite inexpensive so first and foremost if you have an animal that has like this chronic gi
disease maybe they've got chronic diarrhea nothing has worked you've tried a bunch of different
things now why don't you go and pick up some of this this is the soluble fiber psyllium husk
many people know it as metamucil by being a soluble fiber when water is added to the psyllium husk
it forms this thick gelatinous or jelly-like layer i'm going to show you actually typical
psyllium husk dose about one teaspoon yay per 20 pounds of body weight i'm just going to mix it
into this cup and show you what happens okay so after waiting a bit look at that
really unappealing but that's what it does in the intestinal tract you give it to your
cat to consume water and here it is right here like look at that gel that's what it turns into
and it tastes healthy but it's all good but one study found that when they're giving to
these shepherds these are working german shepherds had chronic diarrhea non-responsive
dementia dinosaur steroids etc that's what they responded to but they responded to really high
doses of four tablespoons a day of psyllium husk but on this within two weeks most of their
diarrhea resolved after a month majority of these dogs were cured right all from psyllium husk so
you have this soluble fiber coats the intestinal tract decreases inflammation probably helps
repair some of the damaged cells right where there is intestinal permeability so don't scout psyllium
husk good option one of my favorites here the slippery elm slippery elm it acts similar to that
psyllium husk but it offer also offers medicinal value first and foremost it's super duper darn
safe all right like there's virtually no side effects pretty convenient coming in a capsule
you can be dosing in about one capsule for 20 pounds of body weight daily because it's one
one capsule is 400 milligrams it does the same thing you add liquid open this powder up add
liquid to it it forms this mucoid like gel as well acting very similar to the psyllium husk
it also seems to be beneficial for coughing we see it beneficial for diarrhea we see it
beneficial for constipation even helps for urinary tract disease right slippery elm mother's first
milk colostrum the colostrum is wonderful at gut healing it is it's got a pile of studies
and research behind it and so one of the real big big benefits is healing a dog or cat that has
leaky gut and it's a relatively inexpensive supplement really really safe has been well
well studied for our dogs and cats as well as people etc etc there's a bunch of different
co-factors a number of different medicinal nutrients found within colostrum that directly
decrease inflammation along with direct one directly decrease inflammation right it's
maybe the underlying cause of the leaky gut secondarily it'll actually aid and speed tissue
repair bringing in the right healing cells are actually going to be coordinated and actually
rebind that gut together and one of its first research was looking at the use of colostrum
that help repair intestinal cells have been damaged by NSAID your dog or cat's been on
something like this the medicam cause like gastric irritation intestinal irritation maybe even an
ulcer like one of the specific treatments well studied is this colostrum so doses of 100
milligrams for 10 pounds of body weight daily right and if you have an animal and you're not
really sure there's been some GI stuff maybe not and you're like is there like one thing i could
just just try that's pretty darn safe inexpensive colostrum is a good option because it's a capsule
like this easy to give also really beneficial to help boost the immune system collagen like the
most abundant protein i've found within the body majority of the intestinal tract what's it made
collagen your dog or cat skin our skin so it's mostly made up of this collagen so one of the key
things within collagen it provides some of the key amino acids that are essential for gut health and
gut repair and there's a bunch of different amino acids there's a few in particular where i'm going
to talk about those last two at the end because in some cases just providing them alone making for
better benefit but especially for an animal we're not really sure you wanted to supplement
your dog or cat with something else like you have the underlying suspicion they've got chronic GI
disease it's just not quite right along with maybe some other chronic inflammatory disorder
maybe you've got an animal with allergies you're like what else can i try collagen's not a bad idea
as far as an approximate dose i would suggest about one gram or a thousand milligrams
per 30 pounds of body weight daily the last two remedies were actually really specific for leaky
gut and there's something you should be considering especially if you're going ahead you've done the
testing and you're sort of leaning towards your dog or cat having leaky gut you really want to
think about using these this one here L-glutamine L-glutamine it's an amino acid considered a
conditionally essential amino acid in terms of other amino acids should be able to make it but
you don't necessarily have enough of those and this may be the direct issue for animals that
have leaky gut think about L-glutamine as the fuel that you know what supports those
intestinal cells to work properly there's no fuel in your cells the mitochondria can't function
normally no cell can't those cells can't work normally they can't break down digest food
they can't properly you know decide what goes in what goes out that's why L-glutamine is so
important and so widely used with people as well the other interesting fact i think somewhere
between 70 to 80 percent of our immune system based within our intestinal tract so what many
people are finding is when they supplement with L-glutamine they actually have less sort of chronic
disease and especially say they've got kids that come home with colds every three or four weeks
they're getting less of those colds because they have a much more robust intestinal health
meaning they have a much more robust immune system all from L-glutamine and it's relatively inexpensive
serves typical animal doses about a thousand milligrams these are 1000 milligram capsules
for 30 to 40 pounds of body weight daily and this is something you definitely want to consider if
we've got an animal that has leaky gut L-glutamine and you could just open up a capsule each one is
a thousand milligrams right and just sprinkle it onto your pet's food and or giving the capsule
capsule directly a last but not least there's a supplement called zinc carnosine so carnosine
is a peptide meaning it's made up of two different amino acids and is bound to zinc which has some
great tissue healing properties zinc is widely used for instance to increase skin repair
i personally used it when i fractured my collarbone it's been shown to really increase
the rate of bone healing right so it plays a big role in promoting the correct healing processes
so here we have an animal that has leaky gut carnosine itself it plays a big role in the
formation of the glue that goes between the lining of the gut cells and that's probably its biggest
we're trying to think of a reason why you're using it is these two amino acids making up carnosine
are really important in the lining of the gut and the layer between the enterocytes or the gut cells
right to provide those building blocks decrease inflammation so the zinc some of the other
nutrients we've been giving add in carnosine there's in the form of zinc carnosine then we
can actually help rebuild that layer or we've lost you know the glue between the enterocytes
of the cells right and that's what there has it has been widely used in veterinary medicine
there are some specific veterinary supplements which include zinc carnosine and if you have an
animal that has leaky gut you want to get them on it the reason i've got this bottle here i went
to try to buy some locally i couldn't find any unfortunately but a standard carnosine carnosine
dose about 30 milligrams for 50 pounds of body weight daily is a standard amount so you don't
need very much and it's considered a relatively inexpensive supplement on top of that fact so you
can just you know if you had to choose all the different things i talked about you know you could
you know obviously start with diet but if you want to try you look at sort of two specific like
really focused leaky gut nutrients number one the l-glutamine number two the zinc carnosine
i actually don't have all the ones i've been researched like really key for leaky gut
it's ensure you're using adequate doses you know a thousand milligrams per 30 pounds daily
l-glutamine 30 milligrams per 50 pounds daily of zinc carnosine so if you have a dog or cat
with chronic intestinal disease first and foremost i mean obviously you've probably seen
your veterinarian if one of your concerns is like could it be leaky gut at the very least consider
some form of diagnostic test look at the diagnostic tests offered through innovative pet labs consider
something like the complete gut health check with a specific focus on leaky gut and then based on
those results and whether you choose to do that or not then consider some of these remedies there's
some pretty you know good common sense ones where you're starting with diet you're eliminating as
much as you can some other processed food maybe adding in some anti-inflammatory toppers be it
pumpkin maybe even blueberries which are another great source of antioxidants even a good source
of prebiotics to help the good bacteria grow and then consider some of those specific remedies i
discussed be it psyllium husk be it the probiotics right be it the slippery elm i'm looking at the
l-glutamine maybe consider collagen considering zinc carnosine thanks so much for watching this
