UltraK9 Pro Review: A Dog Owner Reads the Label and Does the Math
A chicken-broth-flavored liquid with ten named plant and animal ingredients, aimed at the dog who is slowing down: joints, energy, coat. The ingredient list is clear and the refund window is long. The doses are small, and the sales page promises more than the label can carry.

UltraK9 Pro is worth considering if your dog is getting older, the walks are getting shorter, and you want a single liquid that covers joints, energy and coat without a pill fight at dinner. The ingredient list is public and every item on it has at least some research behind it. What the sales page does not tell you is the dose, how long a bottle lasts for a 70 lb dog, and how the refund really works. That is what this page is for. I have not given it to my own dog, so nothing here is a test result. I read the label and the refund policy and checked them against what is known about each ingredient.
What UltraK9 Pro is, in plain words
UltraK9 Pro is a liquid dietary supplement for dogs, sold by the brand of the same name through its official website, with payment processed by BuyGoods. It comes in an amber glass bottle with a black dropper. Copies of the label call it a "delicious proprietary primal nutrient blend" and list three jobs: "modulates healthy weight and metabolism", "maintains lustrous coat and healthy skin", and "supports strong joints and flexibility". It is sold as a dietary supplement, not as a food or a medicine.
The practical part is the taste. The brand says it tastes like rich chicken bone broth, and that you can add it to any kind of meal, dry or wet, store-bought or homemade. Anyone who has tried to get a joint tablet into a Labrador who has learned to eat around it will understand why a liquid that smells like broth is a selling point on its own.
The pitch on the official site is built around the idea of "primal nutrients", plant roots and animal proteins that a dog's ancestors would have found on their own. I will leave the story aside and stay with the two questions an owner actually has: what is in the bottle, and how much goes into the bowl. The brand talks about a dog living "the best years" of its life, which in practice means the product is aimed at the dog who is slowing down. If that sounds like your dog, our guide to the signs a dog is slowing down is a good companion to this page, because a supplement is never the first step when a dog stops jumping on the couch.
The label, line by line (and the 9 or 10 question)
Here is everything I could confirm on the official page, plus what the label reportedly says. I checked the official site on October 20, 2026. The per-ingredient amounts and the dose come from copies of the label published elsewhere, not from the official page, so I mark them as reported. Check the bottle you receive.

So, 9 or 10?
The sales page says "9 special high-quality primal nutrients" and then lists ten. For a while I assumed a typo. The label copies explain it: nine ingredients sit inside the named nutrient blend with an amount next to each, and MCT oil is listed separately under "other ingredients", the way a carrier oil usually is. So the brand counts nine actives and one carrier. Nothing is missing. It is a labeling convention, and better to hear it here than to wonder about it at checkout.
The more useful observation is the size of the amounts. If the reported label is right, a full dropper carries 12.5 mg of turmeric and 50 mg of collagen. The dog studies on those two ingredients, including the one the brand cites, used far larger daily amounts. That does not make the product useless, and it is the main reason the score is not a perfect 5. You are paying for a broad, gentle blend. Nobody should expect a therapeutic dose of any one thing from it.
The 10 ingredients and what the research says
One card per ingredient. Each starts with the brand's claim, labeled as the brand's claim, and then what the research I could find shows, in dogs wherever dog research exists. None of it is research on UltraK9 Pro itself. The brand's reference list is a mix of dog studies, rat studies and human trials, and I say which is which.
Joints and mobility
Turmeric
The brand says: healthy inflammatory response, joint and ligament support. The research: a 2017 placebo-controlled trial in dogs with osteoarthritis (Comblain and colleagues) found that a diet with curcuminoids, hydrolyzed collagen and green tea extract improved owner-reported pain scores. The curcumin dose there was many times what a 12.5 mg serving provides. Turmeric can also add to the effect of blood-thinning medication.
Bovine collagen
The brand says: joint health, mobility, protein. The research: hydrolyzed collagen has a few dog trials behind it, including a 2014 study on elbow dysplasia in young dogs and the 2017 trial above. Those used grams per day, not 50 mg. Good ingredient, small amount. If joints are the main worry, read our piece on whether glucosamine works for dogs for the bigger picture.
MCT oil
The brand says: easy to digest, boosts turmeric. The research: medium-chain triglycerides are well studied in dogs. A 2012 study in healthy beagles (Hall and Jewell) found that MCTs with fish oil and carnitine offset some age-related changes in blood fatty acids. Fat also helps the body absorb curcumin, so the pairing makes sense. On the label, MCT oil is the carrier.
Horsetail
The brand says: bone health, rich in calcium. The research: horsetail is a silica source, and the bone studies are in rats and in cells, not dogs. It is also a mild diuretic, which matters for a dog with kidney disease or one already on a diuretic. Traditional ingredient, thin dog evidence.
Energy and stress
Ashwagandha
The brand says: thyroid support, helps the dog relax. The research: the brand cites a 2020 study in horses showing adaptogenic and immune effects, and a 2018 human trial in people with mild low thyroid function. I found no controlled trial in dogs. Because ashwagandha can nudge thyroid hormone levels and has a calming effect, a dog on thyroid medication or a sedative needs a vet's okay.
Ginseng
The brand says: minerals, weight and metabolism, immune support. The research: a 2019 study of Korean red ginseng in healthy beagles (Bae and Oh) looked at body weight and fat markers over several weeks and is the brand's main dog citation. One small study. Ginseng can affect blood sugar and interact with some medications, so it belongs on the list you show your vet.
Astragalus root
The brand says: adaptogen, digestion, heart support. The research: a long history in traditional medicine and a fair number of lab and rodent studies on immune markers. Dog data is scarce. At 25 mg it is the second-largest plant ingredient in the blend.
Liver, kidneys and coat
Burdock root
The brand says: liver and kidney support, soothes the stomach. The research: a 2011 review of burdock (Arctium lappa) pharmacology covers antioxidant and anti-inflammatory activity in lab models. It is also a source of inulin, a prebiotic fiber. No dog trials that I could find. Mild, traditional, low risk at this amount.
Dandelion root
The brand says: protein and vitamin A. The research: dandelion is a well-known herbal diuretic and a source of potassium and vitamin A. Dog-specific trials are lacking. Like horsetail, it is the ingredient to mention if your dog has kidney trouble or takes a water pill.
Chicken bone broth
The brand says: delicious, easy on the stomach, good for skin, coat and bones. The research: bone broth is mostly a flavor and a modest source of collagen peptides and minerals. At 50 mg it is there for taste first, and that is a real job: a supplement a dog refuses does nothing.
The honest summary of the science
Every ingredient has a reason to be there. Turmeric, collagen and MCT oil have real dog studies; ginseng has one; ashwagandha, horsetail, burdock, dandelion and astragalus are traditional ingredients with lab, rodent, horse or human data and not much in dogs. The brand's reference list is genuine, but several of the papers it cites are about overweight dogs in general, not about this product, and the doses in the dog trials are bigger than what a dropper delivers. That is the whole case. The blend is thoughtful and the list is honest; the amounts are gentle.

How to use it: dose by weight, how long a bottle lasts, cost per day
This is the part the sales page leaves out, and the reason this page exists. The official sales page does not print a dose. It says "every drop" and "add to any kind of meal". The directions below come from copies of the label published elsewhere, and they conflict with some older pages that say "one dropper a day". So these are reported directions. Check the bottle you receive, and ask your vet if the two disagree.
Reported label directions: dogs up to 24 lb, one full dropper (1 mL); 25 to 55 lb, 2 mL; 56 lb and over, 3 mL; given two to three times a day with food. One bottle is reported as 2 fl oz, which is 60 mL. Put those two facts together and the "one bottle a month" line you see everywhere only holds for a small dog.
| Dog weight | Reported dose per day | Days per 60 mL bottle | Cost per day at $69 / bottle (3-pack) | Cost per day at $39 / bottle (6 or 12-pack) |
|---|---|---|---|---|
| Up to 24 lb (small) | 2 to 3 mL | 20 to 30 | $2.30 to $3.45 | $1.30 to $1.95 |
| 25 to 55 lb (medium) | 4 to 6 mL | 10 to 15 | $4.60 to $6.90 | $2.60 to $3.90 |
| 56 lb and up (large) | 6 to 9 mL | 7 to 10 | $6.90 to $10.35 | $3.90 to $5.85 |
Two things jump out of that table. First, for a medium or large dog the 3-bottle kit is roughly a month's supply, not three months. Second, the difference between the 3-pack and the 6-pack is $27 in total, and it almost halves the cost per day. If you have a 40 lb dog and you intend to use the product for the full 60-day guarantee window, six bottles is the size that actually covers the trial. I come back to that in the price section.
What to expect in the first weeks, in the brand's own words from its FAQ: "starting in the first one or two weeks" you might see the coat shine and more energy on walks, and "the long lasting results appear after 6 months to a year". I am quoting the brand there, and a quote is not a promise. Here is the plan I would follow with any new supplement:
- Start at the low end of the reported range for the first few days and watch the stool. A new fat source (MCT oil) can loosen things briefly.
- Change one thing at a time. If you start a new food, a new joint chew and this liquid in the same week, you will never know which one helped.
- Keep a three-line diary: how your dog gets up in the morning, how the walk ends, how the coat looks under a lamp. Memory is a poor judge of slow changes.
- Decide by day 45. The refund window is 60 days from delivery. That leaves time to mail the bottles back if it did nothing.
What owners say on the official site
The brand publishes three customer quotes on its sales page. I am reproducing them exactly as shown, with the names and places the brand gives.
"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
These testimonials are published by the brand on its official site. We could not verify them, and individual results vary.
Pros and cons of UltraK9 Pro
What I like
- All ten ingredients are named on the official site; nothing hides behind a vague "wellness blend"
- Turmeric, collagen and MCT oil have published dog studies, and MCT oil is a sensible carrier for curcumin
- Liquid with a chicken broth taste: it goes on kibble, wet food or home-cooked meals without a fight
- Covers joints, energy and coat in one bottle, which suits the owner of an aging dog who does not want three products
- 60-day money-back guarantee and a one-time payment, with no subscription to cancel
- The 6-bottle kit costs only $27 more than the 3-bottle kit and cuts the per-bottle price from $69 to $39
- No stimulants, non-GMO, and the brand displays GMP and FDA-registered facility seals
What I would change
- Proprietary-style blend with small amounts (12.5 mg of most herbs); the dog studies used far more
- The dose is not printed on the sales page, and reported label directions differ from older pages
- No single-bottle option: the entry price is $207 for three bottles
- For a dog over 55 lb, a bottle lasts about a week to ten days at the reported dose
- On a refund, you pay the return shipping and must send every bottle back
- $15.95 shipping outside the United States, and 10 to 15 working days
- The sales page leans on urgency and big claims that the label does not support; results vary
Price in 2026 and the cost per day
Older pages may show different prices. The figures below were read on the official site on October 20, 2026: the official site sells three kits, there is no single bottle, and the per-bottle price drops hard between the 3-pack and the 6-pack. All three kits ship free in the United States.
The math is unusual and worth saying plainly. Three bottles cost $207. Six bottles cost $234. For $27 more you get twice the product, which is why most people will land on the 6-pack. The 12-pack is no cheaper per bottle than the 6-pack. It only makes sense for a large dog going through a bottle every week or two, once you have already decided to keep going past the trial.
The two free bonus guides on the 6 and 12-bottle kits cover grooming and training. They are a small extra, not a reason to choose a size. Choose the size by your dog's weight and the dose table above.
Shipping, per the official shipping table: United States free, 5 to 7 working days. Canada, the UK and Ireland, Australia and New Zealand: $15.95 per order, 10 to 15 working days.
Prices were read on the official site on October 20, 2026 and can change. The official page always shows the current figure.
How the 60-day guarantee works, step by step
The sales page says: if you are not impressed with the results, write to them at any time in the next 60 days and they refund every cent. The refund policy adds the conditions, and I would rather you read them here than discover them later. Per the refund policy: the 60 days count from the day your order is delivered, not the day you paid. You email the support team with "Refund Request" in the subject line. You return all the bottles, opened or empty, to the address in Tallmadge, Ohio, given in the policy, with a note carrying your name, email and order number, and you pay the return shipping. The policy says the refund is processed a few days after the package arrives and can take 5 to 10 days to show on your card.
Two more details. There is no phone line; order support goes through BuyGoods, the payment processor, and product questions go through the brand's contact form. And the refund page itself suggests using the product for three months, while the window is 60 days, so plan around the 60, not the 90.
Practical steps: keep the order confirmation email, note the delivery date, keep every bottle in a drawer during the trial, and put a reminder on day 45. That leaves two weeks to pack and ship if the product did nothing for your dog.
UltraK9 Pro or PawBiotix?
Both are liquid dog supplements sold through BuyGoods with a 60-day guarantee, and readers ask which one to pick. They do different jobs. PawBiotix is a probiotic: its purpose is the gut, and it belongs with soft stool, gas and a touchy stomach. UltraK9 Pro is a nutrient blend aimed at the dog who is slowing down: joints, energy and coat. If your main worry is the gut, read our PawBiotix review. If your main worry is a dog who hesitates at the stairs and sheds more than she used to, you are on the right page. If both are true, start with one, give it a few weeks, then ask your vet about adding the other.
Safety, side effects and who should ask a vet first
The brand's page does not mention side effects, and at the reported amounts the ingredients are gentle. The usual early effects with any new liquid supplement are mild: a day or two of softer stool while the stomach adjusts to a new oil, or a dog who sniffs the bowl a little longer the first time. Neither is a reason to stop unless it continues.
Stop the supplement and call your veterinarian if you see vomiting, hives, facial swelling, repeated diarrhea, unusual lethargy or a refusal to eat. Those are signs of a reaction to an ingredient, not an adjustment. If your dog collapses or has trouble breathing, that is an emergency: go to the nearest emergency clinic.
Dogs that should have a vet's okay before starting, because of what is in the bottle:
- Puppies and growing dogs. The brand says it suits any age, and one of its testimonials is about a puppy, but adaptogens like ashwagandha and ginseng have no safety data in growing dogs. Ask first.
- Pregnant or nursing dogs. Standard advice for any herbal blend, and especially for ashwagandha.
- Dogs on thyroid medication. Ashwagandha can shift thyroid hormone levels; a vet may want to recheck bloodwork.
- Dogs on sedatives, anxiety medication or blood thinners, or scheduled for surgery. Ashwagandha adds to sedation; turmeric and ginseng can affect clotting and blood sugar.
- Dogs with kidney or liver disease, or on a diuretic. Horsetail and dandelion are mild diuretics, and the liver processes everything in the bottle.
- Dogs with a chicken or beef allergy. Chicken bone broth and bovine collagen are both in the formula.
None of that is unusual for an herbal supplement; a vet would run through the same list for most products in this category. Bring the ingredient table above to the appointment and the conversation takes two minutes.
How to buy UltraK9 Pro safely
The brand sells UltraK9 Pro through its official website only, with payment processed by BuyGoods. If you see it on a marketplace, in a "news article" promising a miracle, or in an ad that uses a celebrity or a doctor, that is not the brand's material, and the 60-day guarantee does not cover it. The buttons on this page go to the official order page, where you pick a kit, enter your shipping details and pay once. There is no subscription box to untick, which is one less thing to check.
Frequently asked questions
Does UltraK9 Pro really work?
There is no published study on UltraK9 Pro itself. The research is on its ingredients: turmeric, collagen and MCT oil have dog studies, at larger amounts than one dropper provides. Whether the blend helps your dog is something a trial inside the 60-day refund window will show. Results vary, and your vet should see the ingredient list first.
How much UltraK9 Pro should I give my dog by weight?
The official sales page does not print a dose. Copies of the label published elsewhere report one full dropper (1 mL) for dogs up to 24 lb, 2 mL for 25 to 55 lb and 3 mL for 56 lb and up, given two to three times a day with food. Treat that as reported, not confirmed, and follow the directions printed on the bottle you receive.
How long does one bottle of UltraK9 Pro last for a small, medium or large dog?
If the bottle holds 60 mL and the reported label directions are right, a bottle lasts about 20 to 30 days for a dog under 25 lb, 10 to 15 days for a 25 to 55 lb dog and 7 to 10 days for a dog over 55 lb. The common claim that one bottle is a month only holds for small dogs.
Why does UltraK9 Pro say 9 primal nutrients but list 10 ingredients?
The sales page names ten ingredients. On copies of the label, nine of them appear in the nutrient blend and MCT oil is listed separately under other ingredients, as the carrier oil. That explains the 9 versus 10. It is a labeling detail, not a missing ingredient.
How long does it take to notice a difference with UltraK9 Pro?
The brand's own FAQ says you might see coat, energy or stomach changes in the first one or two weeks, and that long lasting results appear after six months to a year. Those are the brand's words, not a promise. A practical plan is to judge it inside the 60-day refund window, which starts at delivery.
How does the UltraK9 Pro 60-day refund work, and do I have to send the bottles back?
Per the refund policy, you have 60 days from delivery to request a refund, you send back all bottles, opened or not, to the address in Tallmadge, Ohio, given in the policy, with a note carrying your name, email and order number, and you pay the return shipping. Order support is handled by BuyGoods, the payment processor; product questions go through the brand's contact form. Keep your order number.
Does UltraK9 Pro have side effects, and which dogs should see a vet first?
The brand's page does not mention any, and the amounts per dose are small. The ingredients that deserve a vet's okay are ashwagandha and ginseng (thyroid medication, sedatives), turmeric (blood thinners, surgery), horsetail and dandelion (kidney disease, diuretics). Puppies, pregnant or nursing dogs, and dogs with kidney, liver or thyroid disease should get a vet's okay before starting any supplement.
Can I give UltraK9 Pro together with a probiotic like PawBiotix?
The two products do different jobs: UltraK9 Pro is a nutrient blend aimed at joints, energy and coat, and PawBiotix is a probiotic aimed at the gut. There is no listed ingredient overlap except turmeric and collagen, both in small amounts. Ask your vet, start one product at a time, and give each a couple of weeks before adding the other so you know what changed.
Is the Ultra K9 Pro sold on Amazon the same product?
The brand sells UltraK9 Pro through its official website only, with payment processed by BuyGoods. A listing on a marketplace is not sold by the brand, and the 60-day guarantee applies only to orders placed on the official site. Buy only from the official site.
Verdict: 4.7 out of 5
UltraK9 Pro earns its score on the ingredient list, the format and the terms. Ten named ingredients, three of them with real dog studies, in a broth-flavored liquid that goes on any meal, with a 60-day guarantee and a single payment. The 6-bottle kit at $39 a bottle is fair value for a small or medium dog, and the "no stimulants" line and the facility seals are the kind of thing I like to see. The few points it gives up are for the small amount of each herb compared with the research, a dose you have to learn from the bottle instead of the sales page, the three-bottle minimum, a refund that costs you return postage, and a sales page that promises far more than any label can carry. Does UltraK9 Pro work? The ingredients can support an aging dog's joints, energy and coat. Whether this blend does that for your dog is something only a 60-day trial will tell you. If your dog is slowing down, your vet has no objection to the ingredients above, and you pick the kit that actually covers 60 days at your dog's weight, it is a reasonable experiment with the money back if nothing changes.
