Stomach Tonic

Stomach Tonic comes in a liquid form; this is the easiest way to administer it to animals. It can be put straight into the mouth of the animal, making sure not to contaminate the dripper. You can do this by adding the drops to a teaspoon, lifting the lip, and place in the mouth. But we realise this is not always an option. So you can add the drops to their food, which is just as effective.

Dosage: 4 drops 1/2 hour for 4 doses. 

How long will a 25ml bottle last: (based on the above dosage as 1 course)

Cats and Dogs: 23 courses per bottle

It can also be administered daily to promote good bowel health.

All instructions are on the bottle.

About our ethanol base

At Natural Pet, our liquid remedies are preserved using organic-certified ethanol derived from a mild cane or wheat base, gently prepared at just 10% concentration. This helps support product integrity while remaining palatable and suitable for daily use.

Ethanol and your furry friend's well-being

Each dose contains only 0.4 of a drop of ethanol, and most dogs and cats tolerate it without issue. However, if your pet shows sensitivity, you can:

• Add the drops to food or a treat and let sit for 20 minutes before offering

• Mix with a small amount of water and allow to stand for 20 minutes before dosing

For dogs and cats with heightened sensitivity, we recommend starting with diluted dosing and observing for comfort and acceptance.

We choose ingredients that honour both purity and purpose. Our ethanol is part of that commitment—organic, clean, and thoughtfully balanced to support your animal’s health journey.

  Stomach Tonic

  This is very effective for gastrointestinal upsets. Have used it for both cat and dog vomiting or diarrhoea which has subsided in a day. Given 1/2 hourly for 4 doses and then 3 times a day if needed.

  Turned Sprite's life around.

  I want to say that you have completely turned my cat, Spite's, life around. He was getting an upset stomach/leaking bowels every three months or less. I’ve had him since he was 2 weeks old, and he was a foster fail, and I was at my wits' end trying to figure out what was going on. Ever since he started using your products, no more! I've used Stomach Tonic, Poly Bowel and Gut Support, which has done the trick. Thanks again :)

  nursed my kitten back to good health after severe diarrhea and lack of appetite

  the question still lingers whether it was food intolerance, the help of this tonic, or both. however, i have changed my kittens food. but also i strongly believe that the ease of this transition and recovery time is strongly due to the use of this stomach tonic. basically i got him at about 8 weeks, he had on and off diarrhea since i got him. he wasn't previously wormed and i thought regular worming was what he needed. it wasnt the whole issue though. it got so bad i actually feared the worst. the litter visits he made, had the most horribly uncomforable sound and grew more and more like straight liquid with the frequency also increasing drastically (3-5 times a day). his lack of appetite got really bad also to the point he was having the smallest amount of food each day since i got him. his food was going bad and needed to be discarded and refreshed, basically untouched and even then he only really was eating a very small amount of busicuts and next to none of his wet food. i knew his appetite was alot larger when i first got him and this ment he was on a pretty acute decline physically. i found online and ordered this tonic, it arrived the next day and ever since things have drastically improved. that day it arrived i hadn't used it yet as i had managed to get a vet appointment that same day and thought it best to delay untill he was checked out. in the vet appointment there was no problems or alarm bells and they put it down to his food, which was switched instantly after visit. the vet visit did ease my mind but also as soon as i got home i started administration of this tonic. i knew he needed all the goodness/help he could get along with a change in food. he came right the very next day. i haven't stopped administration as i want him to be as comfortable as possible whilst hes still growing and perhaps even after he hits a year. i have just taken down the dose and frequency of giving him the tonic. and i will continue to do so to what i believe best suits him, his physical health and his age. he actually loves this stuff and i can tell hes excited when i get it out and start sorting the amount of drops that he takes in the dropper. he is a little intimidated by the dropper and wont open his mouth so i gently open it and slowly empty into his mouth. of course there is the option to put it in his food, however for my own preference and peace of mind id rather use this method of administration. he comes right up to me as soon as he sees the preparation which tells me he wants it. he gives off a satisfied nature afterwards. honestly, its as if he just knows its good for him, that it helps him and i think he also enjoys the taste. so as i said will be continuing usage. hes 4 months today and i just want to make totally sure hes not suffering anymore and having this tonic to give him gives me great peace of mind. its a blessing this company exists, they accept afterpay, they ensure fast delivery and have so much variety in terms of what your pet needs in a homeopathic remedy. i myself started my own health journey a year or so back in human ways (herbs and spices, chinese remedies etc) and have found more success than some prescribed medication so i was totally open to this approach for my pet also and the result has been so positive. thank you to natural pet for your dedication to pets and their owners peace of mind. even the over-the-phone questions i had, they were very helpful and i had a more positive interaction with this company than the actual vet. very satisfied and would highly recommend

  Excellent

  I have them this in water as I had seen a couple of vomits and didn’t see who it was - I know which one now - so gave individual doses. They drink out of gutters with tree leaves etc grubby water prob upsets their stomachs. I like this product have used it before for similar purposes if I suspect they have eaten or ingested something manky. It works and settles them makes them better rear and output is back to normal- if it wasn’t within a few days or more worrying symptoms take to vet. Minor issues can be usually treated.

  For a dog with the runs

  My 12 year old Maggie, has had stomach issues for sometime now. She had some serious liver issue back in 2023 and the vet mentioned euthanasia. I instead, set about treating her holistically which worked out well but I think her problems flare up every now and again, and the latest was bad bouts of diarrhea in the middle of the night, sometimes with some bright red blood in it. We sought vet treatment, but I decided to add this remedy to the mix and it seems to do the trick very well, so Maggie lives to tell the tale and at present, she is a very happy doggo and I am grateful for these remedies.

  Stomach Tonic

  I purchased this when my pup got a gastro bug and popped it in his water for 7 days after vet visit I found this really helped him recover and firm up his poos. I take it away with us when camping and pop in his water to kill any nasties. Happy with this product!

  Natural Pet does it again !

  Our 17 year old JR Terrier definitely has/had a few problems (probably liver disease). Our local vets are good but had absolutely no remedy for a very old dog who was losing weight, vomiting after every meal, no appetite because of that, lethargic, etc, bill was >$70 for 10 minutes with no definitive advice (which was fine as they literally didn't have a solution). We contacted Natural Pet and for the last 2 weeks have had our darling on liver tonic, stomach tonic and polybowel. The results have been amazing - she hasn't regained much weight yet but she's eating well, alert, active and obviously enjoying life ! Every day is a bonus for us and we cannot recommend the Natural Pet products enough, extremely well done and incredible value for money.
