Intestinal disorders and digestive problems are quite common in pets, can be non-specific and may recur. The two powdered tree barks in this herbal nutritional supplement have a soothing effect on the digestive tract, slowing the passage of food and increasing absorption of nutrients, firming stools and easing discomfort.

The gentle action and ease of digestion of Tree Barks Powder means it is suitable for use in weaning, during recovery from illness and alongside medication in animals with conditions such as exocrine pancreatic insufficiency. It’s also a good short term choice in animals experiencing bouts of diarrhoea and in the recovery period afterwards, providing relief from intestinal discomfort and for longer term recurrent problems.

for longer term recurrent problems.


Finely powdered slippery elm bark 90 % and white poplar bark 10 %


1 teaspoonful per 10 kgs bodyweight daily added to food, or live yoghurt, or mixed with liquid. Can be increased or given with each feed if required for more severe cases.

Due to the wide range of intestinal disorders, some of which may be serious, it is recommended that veterinary advice be sought before using this product or if the condition fails to improve.

35 Bought to experiment

Floozy has a permanent IBD problem which is kept in remission with steroid. Bought this to see if it would aid her at all. The product has a musty-sweet smell. Mixed into some wet food it was rated without fuss. However, her gas got very smelly. Not sure if this would provide a permanent steroid alternative. User reviews for this product are encouraging & it’s worth a try if your pet is struggling.

55 Made all the difference to my dog's speed of recovery from IBS
Verified Purchase

By on 20 July 2021

This slippery elm powder - half a teaspoon in his food, twice a day - seems to have made all difference to my dog's speed of recovery from a sudden and very bad attack of IBS (irritable bowel syndrome). It has meant that he was quickly back on his normal diet (no expensive special diets or medication) and pain-free. My dog seems not to notice or mind the taste of the powder . Recommend having this in your pet's first aid kit.

Excellent for settling tummies that are a bit out of sorts. Dogs find it palatable and one or two doses in their food normally does the trick. Wouldn't be without it in my cupboard.

What to give a dog that constantly wants to eat grass

Helen Gilbert

My Springer spaniel is on Hills ID as she suffers from GI sensitivity. For about a year she has been on Dorwest Digestive tablets as she used to get excess acid first thing in the morning which made her vomit. This seems to have helped. She is also on a fibre supplement to firm up her stools and reduce issues with anal glands not emptying. She constantly wants to try and eat grass when outside which I prevent so I think she must have nausea or other stomach discomfort. Would this product help or can you suggest anything that would?

  • VioVet Staff

Dogs eat grass usually either behaviourally (as a habit) or because they feel nausious. Tree Bark is a herbal supplement that anecdotally helps settle the guts, this means it might have this effect but it has not been proven to do so.
Preventing the nausia or training your dog not to eat grass is the best approach. I advise following your vets advice closely on how to do this, especially if they have already advised a veterinary diet like Hills ID.

Dog Food portion and Tree Bark

Caroline R

When using the Tree Bark Powder should I keep the dogs food the same amount as usual or reduce it? My GSD boy has a sensitive stomach and reacts to stress. Should I just add the advised amount to his normal food portion or reduce his food?

  • VioVet Staff

This supplement will not change the nutritional requirements for your dog, I would advise adding it to the normal amount of feed to you are currently giving.

Cat with Diarrhoea


i have a 1 year old Maine coon cat who has diarrhea the motions are custard consistency and light brown he weighs about 17 lbs i have been giving him Dorwest Tree Barks Powder for 2 weeks now and only seen a slight improvement how much do you suggest that is the correct amount to be giving him ? can i give more that 1 teaspoon ?

  • VioVet Staff

It sounds like your cat will need an different approach. I am not sure that the Tree Barks powder will be effective even at a higher dose given what you have said. Ideally he should see a vet who could check him over and make sure that there were no other obvious causes for this persistent diarrhoea. If nothing is found, then I would suggest changing the diet to something significantly different to what he is on now. There might not be anything "wrong" as such with the diet, but it is possible that he has developed a sensitivity or allergy to it, or in some other way it does not suit him. He should go on to a simple, good quality cat food based perhaps on either chicken or fish, but different from what he has been on. You could give him a probiotic too for a while and see how things went. If he has not had a worm dose for a while that should be done too. Failing all that, your vet could do some tests which might reveal an underlying cause, so that could be worth following up. I do think that 2 weeks is long enough to decide to try a completely different approach than the Tree Barks product, even though that can be of benefit.

How does it help anal gland leakage ?


My 14 month old pug suffers from her anal glands not emptying and causes her a leaky bum, how will tree bark powder help ?

  • VioVet Staff

This sounds like a slightly confused situation. Anal glands not emptying properly is common in some breeds, though can be helped sometimes by adding fibre to the diet, such as Protexin Pro-fibre. Anal gland trouble will not normally cause leakage from the anus, though anal gland contents themselves might well leak out (quite unpleasantly). The Tree Bark Powder is felt to help with many dietary problems but is very hit-and-miss. It does seem to help in many circumstances but there is not a clear scientific explanation of the mechanisms involved and undoubtedly it will not always help at all. It seems to be safe to try.

My dog has started vomiting yellow bile, hungry but seems uncomfortable when he eats .
Blood tests etc all clear.
Acid reducing syrup from vet seems not to help.
He licks his lips a lot and looks sick.
Can you suggest any of your remedies which may help
Betty Ross

  • VioVet Staff

Tree Barks Powder would be a good supplement to give your dog while you are trying to identify the problem. It is possible that with some help from supplements, your dog will get over the current condition. However it is also possible that there is still an underlying problem which would be best treated by a specific, well directed treatment. This can only happen with a proper diagnosis. Negative results so far just means of course that the cause has not been identified, it does not mean that there is nothing behind the symptoms you see. Referral to a specialist might be needed. Ideally you should try supplements but continue further investigation if symptoms persist. I would also try adding fresh ginger to his diet (the sort of amounts used to flavour oriental food) as well. This can reduce feelings of nausea in some cases, which it sounds like your dog is experiencing.
