UltraK9 Pro Review 2026: What’s Really Inside These Dog Drops
My verdict in one line: ten named ingredients, a broth flavor dogs take willingly and 60 days to try it, a sensible daily add-on for joints, coat and digestion that I have given to my own golden retriever.

What is UltraK9 Pro?
UltraK9 Pro is a liquid food supplement for dogs. You squeeze a dropper of it over your dog’s normal meal — wet food, dry kibble, home-cooked, it doesn’t matter — and the bottle’s own label claims three things: it modulates healthy weight and metabolism, maintains a lustrous coat and healthy skin, and supports strong joints and flexibility.
I want to start with the label, because it’s the clearest thing on the entire product. The bottle says three things: it modulates healthy weight and metabolism, maintains a lustrous coat and healthy skin, and supports strong joints and flexibility. Three verbs, and a formula built to stand behind them.
What a liquid you pour on kibble does is add nutrients that a bag of dry food doesn’t have much of — collagen, bone broth, turmeric, MCT oil — in a form that a dog will actually eat.
The formula is what the producer calls a “proprietary primal nutrient blend”: a mix of plant roots, adaptogens and animal-derived proteins. It’s made in the USA, and the producer states the facility is GMP-certified and FDA-registered.
One practical detail that makes a real difference with fussy dogs: it’s flavoured like chicken bone broth. That’s not a marketing line, it’s the base of the formula. Anyone who has ever tried to hide a tablet inside a piece of cheese for a dog who then eats the cheese and spits out the tablet will understand why a broth-flavoured liquid is a smarter delivery format than a pill.
The label’s three claims, in the producer’s own words: modulates healthy weight and metabolism, maintains lustrous coat and healthy skin, supports strong joints and flexibility.

What’s actually inside UltraK9 Pro?
Ten ingredients, all named on the page: burdock root, ashwagandha, ginseng, astragalus root, dandelion root, turmeric, MCT oil, horsetail, bovine collagen and chicken bone broth. Together they make up the producer’s primal nutrient blend, with the dosing printed on the bottle.
Ashwagandha
An adaptogen, used here for hormonal balance, thyroid support and helping an anxious dog settle.
Ginseng
Mineral-rich root the producer links to steady weight management and immune support.
Astragalus root
Another adaptogen, included for digestion and heart support.
Dandelion root
A source of protein and vitamin A, used traditionally to support the body’s own clearing processes.
Turmeric
The best-researched ingredient in the bottle. Included for a healthy inflammatory response and joint comfort.
MCT oil
Easy-to-digest coconut-derived fat. It also helps the body take up the turmeric alongside it.
Horsetail
A silica and calcium-rich plant, included for bone support.
Bovine collagen
Protein for joint and mobility support — one of the two ingredients with a real trial in dogs behind it.
Chicken bone broth
The base of the formula and the reason dogs take it willingly. Easy on the stomach, and the producer ties it to skin, coat and bone condition. In practical terms, this is the ingredient that solves the “my dog won’t take supplements” problem.
What you are giving: all ten ingredients are named on the official page, and the dosing instructions come printed on the bottle, so you know what goes into the bowl and how much. The 60-day guarantee gives you room to read the label panel when the bottle arrives.
What does the research behind the ingredients show?
The producer publishes a reference list of around twenty peer-reviewed studies on the ingredients, and several are real dog studies. The strongest is a randomised, double-blind, placebo-controlled trial in dogs with osteoarthritis, testing turmeric and hydrolysed collagen, two ingredients that are in this bottle.
In that trial, owner-reported pain and pain on manipulation moved in favour of the supplemented dogs (Comblain et al., BMC Veterinary Research, 2017). It is a real study with a real result, done in actual dogs, not just in the lab.
That supports the label’s own wording, supports strong joints and flexibility, and it is the reason turmeric and collagen sit at the heart of the formula. The rest of the list adds the roots and adaptogens that herbal nutrition has long used, with the bone broth that makes the whole thing easy to feed.
If this is your first dog supplement, the American Veterinary Medical Association has a short, practical read on choosing one (AVMA, Assessing pet supplements). The links to the studies and sources are listed at the end of this page.
How do you actually give it to a dog?
You pour it onto the food and that’s it. No pill to hide, no capsule to crack open, no separate feeding time. Because the base is chicken bone broth, most dogs treat it as an upgrade to dinner rather than as medicine.
Getting it right
- Mix it into the meal rather than dropping it on top — it spreads through kibble better that way.
- Follow the dosing printed on the bottle label.
- Give it daily and at the same meal — this is a slow-building supplement, not a one-off dose.
- Take a photo of your dog’s coat on day one. Coat change is gradual and you will not notice it day to day.
What to expect, and when
- First days to two weeks: energy and mood are what the producer says can show up first, and what I saw first in my own dog.
- First month: digestion and coat, which change gradually.
- Three months and beyond: the producer describes lasting results building with daily feeding.
What did I notice with my golden retriever?
I have been giving UltraK9 Pro to my golden retriever for a little over a month. In the first days he seemed happier and more energetic, and keener on outdoor activities. Over the following weeks his digestion seemed to improve, and his coat looks nicer. That is one dog’s story, and here is what I saw, in the order I saw it.
The changes, in the order I noticed them:
- Energy and mood. Within the first days he seemed happier, with more get-up-and-go for walks and play outdoors. This is the earliest change, and it fits what the producer says can show up in the first one or two weeks.
- Digestion. As the weeks went by, his digestion seemed to improve.
- Coat. After about a month his coat looks nicer. Coat change is gradual, which is why it is the last thing I noticed.
One dog’s experience: a little over a month, with no vet measurements, so your own dog may respond differently. The producer says lasting results build over months of daily feeding.
Why is UltraK9 Pro worth it?
UltraK9 Pro is worth it because it is one dropper over the meal: ten named ingredients, research behind the headline ones, a broth flavor dogs accept, free shipping in the US and 60 days to see how your dog takes it.
Ten named ingredients
Turmeric, collagen, bone broth, MCT oil and six more, all named on the official page.
Research behind it
A placebo-controlled trial in dogs with osteoarthritis backs turmeric and collagen, and the producer cites around twenty studies in total.
A format dogs accept
Chicken bone broth flavor, a dropper and no pill to hide. It goes on the meal like an upgrade to dinner.
Free shipping, 60 days
Every pack ships free inside the US, with 60 days to try it and a full refund if you are not satisfied.
UltraK9 Pro pros and cons
Here’s what I think genuinely earns its place in this bottle.
What I liked
- A good first month with my own dog. More energy in the first days, then better digestion and a nicer coat.
- A sensible ingredient list. Turmeric, collagen, MCT oil and bone broth: familiar ingredients, nothing exotic or invented.
- Real research behind the headline ingredients. Including a placebo-controlled trial in actual dogs, not just lab work.
- A format dogs accept. Broth-flavoured liquid beats a tablet you have to hide, every single time.
- Clear manufacturing claims. Made in the USA, in a GMP-certified, FDA-registered facility, non-GMO.
- 60 days to change your mind with a full refund, long enough to see whether your dog takes it and to notice the early changes.
- Free shipping inside the US on every pack, with a 5–7 day delivery window.
Good to know
- Built for a steady daily routine. The producer describes lasting results building over 3 to 12 months of daily feeding, which is why the packs come with several bottles.
- The 6-bottle pack is the sweet spot: $39 a bottle, against $69 on the 3-bottle pack, with two bonus e-books and free shipping in the US.
What buyers are saying
“After discovering these nutrients, Lola is like a small little puppy again. She is full of life and so happy. We are just a few weeks into using these nutrients and I truly believe it is the best thing I ever did for her.”
Grace Rees · New York, USA
“My goldie, Bobby, has never been happier. Now, at 11 years old, he can outrun most of those younger pups at the park without breaking a sweat. He’s in the best shape of his life and I will make sure to keep him that way.”
Jacob Jackson · Wyoming, USA
“As soon as I started my puppy on these nutrients, he’s been having more energy and it honestly feels like a completely different dog. I can tell how happy and grateful he is that I’m looking out for him.”
Riley Gould · Chicago, USA
The quotes and the five-star badge (11,649 reviews as stated there) come from the producer’s own page. The 4.2/5 on this page is my own editorial score.
Who should buy UltraK9 Pro?
Buy it if your dog eats commercial food and you want to add joint, coat and digestion support in a format your dog will actually eat, and you’re happy to give it a few months of daily feeding. The 6-bottle pack at $39 a bottle is the sensible place to start.
It’s a good fit if…
- ✓Your dog eats mostly dry commercial food and you want to top up what the bag doesn’t provide.
- ✓You have an older dog slowing down on walks and you want joint and mobility support.
- ✓Your dog refuses tablets, powders and anything that looks like medicine.
- ✓You’re happy to run it for three months or more and judge the result then, not next week.
- ✓You want a money-back window rather than a blind purchase.
UltraK9 Pro price, packs and bonuses
UltraK9 Pro comes in three packs, all with free shipping in the US: 3 bottles at $69 each ($207), 6 bottles at $39 each ($234) or 12 bottles at $39 each ($468). The 6 and 12-bottle packs also include two bonus e-books. Prices are set by the producer and can change.
| Pack | Bottles | Per bottle | Total | Bonuses |
|---|---|---|---|---|
| Basic Pack | 3 | $69 | $207 | — |
| Small Boy Pack | 6 | $39 | $234 | 2 free e-books |
| Big Boy Pack | 12 | $39 | $468 | 2 free e-books |
Prices as shown on the official order page at the time of writing, September 2026. Free shipping in the United States; $15.95 to Canada, the UK and Ireland, Australia and New Zealand.
The two bonuses, and what they’re worth
Order 6 or 12 bottles and two e-books come with it. The first is a groomer’s guide to coat and teeth — brushing technique, spotting dental trouble early, reducing shedding. The second, Best Dog, Best Owner, is a training and behaviour guide.
The 6- and 12-bottle packs include two e-books, a training guide and a grooming guide. I have read both and found them genuinely useful: the training guide helps you understand what your dog is trying to tell you and has practical training tricks. If you choose the 6 or 12-bottle pack, they are a real extra.
My take on which pack to choose: the 6-bottle pack is the sensible middle. At $39 a bottle it gives you the few months of daily feeding the producer describes, it includes the two e-books, and the 60-day guarantee covers you.

UltraK9 Pro FAQ
What is UltraK9 Pro and what does it actually do?
UltraK9 Pro is a liquid food supplement for dogs that you add to a regular meal with a dropper. Its label makes three claims: it modulates healthy weight and metabolism, maintains a lustrous coat and healthy skin, and supports strong joints and flexibility. It is a supplement, not a medicine, and it is not intended to diagnose, treat, cure or prevent any disease.
How do you give UltraK9 Pro to a dog?
You add it straight to your dog’s food, wet or dry, home-made or store-bought. The producer says it tastes like rich chicken bone broth, which is why most dogs take it without any hiding or disguising. Dosing instructions come printed on the bottle label, so you have them in hand the day it arrives.
Is UltraK9 Pro suitable for puppies and senior dogs?
The producer markets it for dogs of any age or condition, and its ingredients are familiar names in dog nutrition: turmeric, collagen, MCT oil and chicken bone broth. Supporting strong joints and flexibility is one of its three label claims, which makes it a natural fit for an older dog.
How long does UltraK9 Pro take to work?
The producer says coat and energy changes can show up in the first one or two weeks, with lasting results building over several months of daily feeding, or about three months for dogs already on a raw or home-cooked diet. That is why the larger packs exist, and why the 6-bottle pack is the sweet spot. In my golden retriever’s case, more energy showed up in the first days and digestion and coat seemed to improve over the following weeks.
Have you tried UltraK9 Pro on your own dog?
Yes. I have given it to my golden retriever for a little over a month. More energy showed up in the first days, and his digestion and coat seemed to improve over the following weeks. That is one dog’s story, with no vet measurements, so your own dog may respond differently.
How much does UltraK9 Pro cost?
At the time of writing the official page sells three bottles at $69 each ($207 total), six bottles at $39 each ($234 total) and twelve bottles at $39 each ($468 total). Shipping is free inside the United States on every pack, and the six and twelve-bottle packs also include two bonus e-books. Canada, the UK and Ireland, Australia and New Zealand pay $15.95. Prices are set by the producer and can change.
Is shipping free with UltraK9 Pro?
Yes, inside the United States. Every pack ships free to US addresses, with delivery in about 5 to 7 working days. Canada, the UK and Ireland, Australia and New Zealand pay a flat $15.95, with delivery in 10 to 15 working days.
Is UltraK9 Pro FDA approved?
No. The FDA does not run an approval process for dog supplements the way it does for animal drugs, so no supplement carries one. What UltraK9 Pro does state is that it is made in the USA in a GMP-certified, FDA-registered facility, a statement about the facility rather than an FDA approval of the product.
How does the guarantee and refund work?
The producer offers a 60-day money-back guarantee: if you are not satisfied within 60 days of ordering, you get a full refund.

Home & pet product researcher & writer · Vitherma
I started Vitherma writing about heaters and coolers, and the pets section grew out of the same habit: reading the fine print on products that promise a lot, and reporting what’s actually on the label. More about how I work is on my about page.
To be clear about what I am not: I am not a veterinarian or an animal nutritionist, and nothing here is veterinary advice. This review combines the producer’s published material, the ingredient research they cite, the pricing and guarantee terms as they stand today, and a little over a month of giving it to my own golden retriever. One dog is an anecdote, not a feeding trial.
