Slippery Elm for Dogs: Safely Treat Irritation

This extremely safe herb can soothe any inflammation or irritation.


Slippery elm (Ulmus fulva) is one of the safest herbs commonly given to dogs, and one of the most beneficial.

Herbalists attribute many wonderful healing properties to slippery elm: demulcent (soothing, mucilage-forming), emollient (soothing and protective for skin), nutritive (providing specific nutrients), tonic (promoting healthy function of one or more body systems), and astringent (constricting, binding, or drying effect). It can be used both internally and externally. Slippery elm is one of the herbs used in the original formulation of “Essiac,” an herbal brew that has been widely promoted as a cancer-fighter.

The part of the tree used is the inner bark, which is soft and stringy. Simplest to use is the powdered form, which can be purchased loose or pre-packed in capsules at most health food stores. It is also readily available over the Internet from herb suppliers.

In the gastrointestinal tract, slippery elm acts directly. Think of it as a natural Pepto-Bismol (Pepto-Bismol itself should be used with caution because it contains salicylate, a.k.a. aspirin). Slippery elm’s mucilage content coats, soothes, and lubricates the mucus membranes lining the digestive tract. Slippery elm is an excellent treatment for ulcers, gastritis, colitis, and other inflammatory bowel problems. It is high in fiber, and so helps normalize intestinal action; it can be used to relieve both diarrhea and constipation. It may also help alleviate nausea and vomiting in dogs suffering from non-GI illnesses, such as kidney disease. A syrup made from slippery elm bark (see recipe below) can be used to help heal mouth ulcers.

Slippery elm is said to relieve inflammation of virtually any mucus membrane, and has been used in the treatment of inflammatory conditions of the lungs (bronchitis, asthma), kidneys, bladder (cystitis), throat (tonsillitis), and joints (arthritis).

This wonder herb also contains many nutrients (carbohydrates, protein, fat, ascorbic acid, beta-carotene, calcium, and several trace minerals) that can be beneficial for dogs recuperating from any illness, and it may stay down when other foods are not tolerated.

Externally, a soothing paste of slippery elm powder (mix the powder with a little cold water) can be used as a poultice for hot spots, insect burns, rashes, scratches, ulcerated areas, or other shallow wounds. Native Americans used slippery elm bark to stop bleeding. It forms a natural bandage that can be left in place for several hours, if you can convince your dog to leave it alone! Moisten with water to remove it.

Internal Uses of Slippery Elm

Slippery elm is thought to soothe the bladder lining, making it helpful for dogs suffering from cystitis. Slippery elm bark contains natural pentosans, a class of complex sugars that contains the same compound found in the drug Elmiron, the major pain-relieving treatment for interstitial cystitis in women. However, slippery elm is somewhat high in magnesium and ash, so may be contraindicated in dogs who have an active infection with an elevated urinary pH, where struvite crystal formation may be a risk.

To administer internally, mix about a quarter-teaspoon of slippery elm bark powder with cold water for every 10 pounds of the dog’s body weight. (The quarter-teaspoon dose works fine for dogs who are less than 10 pounds, too.) The bulk powder may be very fluffy, so pack it down as much as possible to measure it.

Alternatively, use a half-capsule (per 10 pounds), opened and the contents mixed with water. Slippery elm powder will absorb many times its own weight in water, so be sure to add enough to make a moderately thick gruel. This gruel can be given before meals by syringe or eyedropper, or added to baby food, canned food, or a homemade diet. It has a slightly sweet taste and is usually well-tolerated by dogs when mixed with food. Administer the dose before or with meals for digestive tract problems, such as inflammatory bowel disease, until symptoms resolve.

Because slippery elm may interfere with the absorption of certain minerals and pharmaceuticals, I would recommend that it be given several hours before or after any concurrent drug therapy.

Slippery elm bark is inexpensive and easy to use; it would be a great addition to your holistic medicine chest!

Recipe for Slippery Elm Syrup

Author Anitra Frazier gives the following recipe for slippery elm bark syrup in her book, The New Natural Cat, which applies equally well to our canine companions when adjusted for weight:

Into a small saucepan, place a half-cup of cold water and one teaspoon powdered slippery elm bark. Whip with a fork. Bring to simmer over low flame, stirring constantly. Simmer one or two minutes or until slightly thickened. Cool, cover, and refrigerate. Keeps seven or eight days. Give a teaspoon of syrup (5 cc) per 10 pounds of body weight five minutes before a meal to minimize diarrhea, or to soothe and heal mouth ulcers.

  1. Slippery Elm…interesting…can it be given on a regular basis? My Beagle has IBD and she has episodes of diarrhea every so often. Would this keep her intestines soothed on a regular basis? Thank you for your help!

    • I’m wondering the same. My dog has been diagnosed with C. Difficile and has been prescribed so many different anti-inflammatories, antibiotics, anti-bacterials that are not working. This has gone on for months with no relief. A friend suggested Slippery Elm for him. I’m willing to try anything at this point. But can he stay on it long term and also I suffer from IBD/IBS could I stay on it long term. Thank you for your help

      • This herb is safe to give to a dog long term. For it to work, give it to your dog an hour before the first meal and before going to bed. My dog has also gastrointestinal issues and nothing worked until I tried this wonder herb. He went from bloody diarrhea to solid brown stool overnight (he had eaten a big piece of raw bone that he shouldn’t have). I plan to keep giving this herb to my dog for as long as I need until I see a regular stool.
        What I do is a mix the herb puree into some plain greek yogurt. My dog loves it.

      • My dog has been fighting cdiff for the last 2 months. He’s on Advita( probiotic), metronidazole and Tylosin. A few days to a week after finishing his meds, his dark green diarrhea comes right back. We’ve tried fecal transplant too. That worked for a few days as well. I read that slippery elm may help him along with probiotics. Anyone Know if this is correct?

    • I have a dog who’s been using this safely for months. To be given twice-daily. If medications are given as 1 hour before or 2 hours after medication as it interferes with absorption.

  2. My dog has chronic UTI’s, and has suffered from passing Struvite stones. She is currently on prescription dog food to prevent the UTI’s and another permanent medication as a pain reliever.

    Would this be safe to give her? She has just recently stopped eating her Urinary SO food so then infections have flared up again.

  3. I’ve been giving this to my dog for years (he’s now 16 1/2). It has helped with his stomach ulcer and IBD issues. I’ve been able to get him off metoclopramide, carafate, and famotidine. I’m an LVT ,and I think my Veterinarians were sceptical at first but can appreciate the results. ☺

    • did you give it to your dog with this food cause thats the only way my dog will eat it she’s done with the syringe cause i had to give her so many terrible medications that way she won’t let us get near her with the syringe anymore thanks

  4. My dog recently had surgery for bladder stones. Surgery determined the stone was Oxolate. Since surgery he has developed pancreatitis. Slippery elm has helped with the pancreatitis, however, I am wondering if it’s safe, as I don’t want my boy to develop stones again.

  5. My dog has been fighting cdiff for the last 2 months. He’s on Advita( probiotic), metronidazole and Tylosin. A few days to a week after finishing his meds, his dark green diarrhea comes right back. We’ve tried fecal transplant too. That worked for a few days as well. I read that slippery elm may help him along with probiotics. Anyone Know if this is correct?

  6. I have a retired greyhound racer and he’s recovering from worms from the track, but still has an irritable bowel. Slippery Elm was recommended. I bought Slippery Elm in 400mg capsule and wondering if you have a dosage based on the milligrams. Thanks

    • Hi Tracy, I’ve just seen your comment about your greyhound recovering from worms. We have a very old Boxer boy Bruce who had lots of problems most of his life and his immune system is so low. He then got roundworm and had to have 2 lots of medication and we even think his lungs were affected by them. Has your dog now recovered from the worms and fo you have any tips at all please? Many thanks, hope your dog is doing well, Julie
