Nine nutrients in a 60 ml dropper bottle — bone broth collagen, turmeric, MCT oil and botanicals — added straight to whatever your dog already eats. No tablets to hide in cheese. Here is what each ingredient does, how to dose it by weight, and when a change in your dog needs a vet rather than a supplement.

A liquid formula mixed into food — not a human supplement repurposed.
Drops go straight into wet or dry food. The format dogs do not refuse.
Non-GMO ingredients, no artificial preservatives, colours or stimulants.
Roughly 1 ml twice daily for small dogs, 2–3 ml for larger adults.
UltraK9 Pro is a daily liquid supplement for dogs. Each 2 oz (60 ml) bottle lasts roughly a month, and you measure drops into your dog's food rather than persuading them to swallow a tablet.
That format is the most practical thing about it. Anyone who has spent five minutes hiding a pill in cheese only to find it licked clean and abandoned on the floor understands why. A liquid mixed into food gets eaten, and with dogs — as with people — the supplement that actually gets taken beats the better one that does not.
The formula lists nine nutrients, with chicken bone broth as the largest ingredient, alongside turmeric, bovine collagen, MCT oil, ashwagandha, ginseng, burdock root, astragalus and dandelion root. It is aimed at owners of older or less active dogs noticing stiffness, a dull coat, or digestive upsets.

Four routes, and the first is the one with the most sensible rationale for an older dog.
Bone broth and bovine collagen supply the amino acids and peptides cartilage is built from. Turmeric adds anti-inflammatory support. For a stiff older dog, this is the most defensible part of the formula.
Burdock and dandelion root are traditional digestive botanicals, and MCT oil is absorbed more easily than most fats. Bone broth is also gentle on a sensitive stomach.
MCT oil and collagen both feed into skin barrier quality and coat condition. Coat is often the first visible thing owners notice changing, usually after a few weeks.
Each ingredient with what it contributes, and an honest note on where canine evidence is thin.
A sensible base. Bone broth supplies collagen peptides, glycine and glucosamine precursors — the raw materials for cartilage and connective tissue — in a form dogs find genuinely palatable. It is also easy on a sensitive stomach, which matters for the older dogs this targets.
Collagen peptides have reasonable evidence in dogs for joint comfort and mobility, and they contribute to skin and coat quality. Alongside the bone broth, this is the part of the formula doing the most recognisable work.
The best-evidenced botanical here for joints, with genuine anti-inflammatory research including some canine work. One caveat: curcumin is poorly absorbed without an enhancer, and turmeric can add to bleeding risk — worth mentioning to your vet if your dog is due surgery.
Medium-chain triglycerides absorb more readily than most fats and have drawn veterinary interest for skin conditions and for cognitive support in older dogs. A reasonable inclusion with a real rationale.
Both are well studied in humans and considerably less so in dogs. Ashwagandha can affect thyroid hormone levels — and hypothyroidism is common in dogs, so if yours is on thyroid medication this is a conversation with your vet rather than an assumption.
Traditional digestive and immune botanicals. Note the dandelion figure where it is published — 12.5 mg is a small amount for an animal that may weigh 30 kg, and most of the other per-ingredient amounts are not disclosed at all.
Each is a possibility rather than a promise, and none has been demonstrated with the finished product in a controlled trial. Extending your dog's lifespan is deliberately not on this list — no supplement has been shown to do that.
Bone broth collagen and turmeric — the most defensible part of the formula for an older, stiffer dog.
Usually the first visible change owners report, typically after three to six weeks.
Bone broth is gentle, MCT oil absorbs easily, and the root botanicals are traditional digestive support.
The change owners most often describe in older dogs — more willingness on walks rather than a transformation.
Turmeric and the botanicals address oxidative stress, which increases with age in dogs as in people.
No pills to hide. It goes in the bowl and gets eaten — which is the whole battle with dogs.
The 3 and 6-bottle packages include two digital guides at no extra cost, covering grooming, dental care and day-to-day dog wellbeing.

Brushing methods, dental care and warning signs worth spotting early.
Included free
Day-to-day habits supporting the same outcomes as the supplement.
Included freeThese are ebooks. Worth saying: dental disease is one of the most under-treated problems in dogs and affects far more than the mouth — so a grooming and dental guide is a more useful bonus than most. Still, choose your bundle on the product, not the guides.
Owner feedback centres on coat condition first, usually three to six weeks in, then willingness on walks in older dogs. Palatability is consistently good — refusal is rare. The recurring practical advice is starting at a low dose.
“Bailey had got slow on walks and his coat had gone dull. Coat improved first, maybe month two, and it is noticeably softer. He is a bit more willing on the long walk now. The vet checked him over before I started and said his joints were arthritic but nothing else was wrong, which was the reassurance I needed.”
Helen M., Colorado — Labrador, 11
“Easiest supplement I have used purely because there is nothing to hide. Goes in the bowl, gets eaten, done. I started at half the dose for a week after reading to do that — good advice, because full dose from day one gave him loose stools on a different product last year.”
Danny R., Texas — Border Collie, 7
“Worth saying: my vet asked what was in it because Molly is on thyroid medication, and she flagged the ashwagandha. We are monitoring her levels. She did not say stop, but she wanted to know. If your dog is on anything, ask first rather than after.”
Priya S., Florida — Beagle, 9

A money-back guarantee applies to every bundle. Confirm the exact window and return conditions on the order page at the moment you buy — that is the version that binds, and terms in this category are sometimes described differently across marketing pages.
Give it a fair trial before deciding. Coat condition is usually the first visible change and takes three to six weeks; joint comfort in an older dog takes longer. Keep your order confirmation email for the order number and note the deadline in your calendar rather than relying on memory.
Ashwagandha can affect thyroid levels and hypothyroidism is common in dogs. Turmeric can add to bleeding risk before surgery. Your vet needs to know what is in the bowl.
Roughly 1 ml twice daily for small dogs, 2–3 ml twice daily for larger adults — but follow your bottle's label. Measure it; do not guess.
The single most useful practical tip. Easing in avoids the loose stools that cause most owners to give up early.
Coat changes are gradual and easy to miss day to day. A photo on day one in the same light makes the comparison honest.

UltraK9 Pro is a daily liquid supplement for dogs, mixed into their food rather than given as a tablet. Each 2 oz (60 ml) bottle lasts roughly a month. The formula lists nine nutrients — chicken bone broth as the largest ingredient, plus turmeric, bovine collagen, MCT oil, ashwagandha, ginseng, burdock root, astragalus and dandelion root. It is non-GMO and made in a GMP-certified US facility.
Measure the dose by body weight and mix it into wet or dry food. As a guide, roughly 1 ml twice daily for a small dog and 2–3 ml twice daily for a larger adult — but follow the label on your bottle. Measure rather than eyeballing it, and start at half the dose for the first week to let your dog adjust.
The finished product has not been tested in a controlled trial, which is normal for pet supplements. The strongest parts are the bone broth collagen and turmeric — collagen peptides have reasonable canine joint evidence, and turmeric has genuine anti-inflammatory research including some veterinary work. Owner reports most commonly describe coat improvement at three to six weeks and better willingness on walks in older dogs. Expect a more comfortable dog, not a rejuvenated one.
Chicken bone broth, turmeric, bovine collagen, MCT oil, ashwagandha, ginseng, burdock root, astragalus root and dandelion root. Most per-ingredient amounts are not published. Where one is — dandelion root at 12.5 mg — it is a small amount for an animal that may weigh 30 kg. Read the label when your order arrives.
The ingredients are generally well tolerated, and the most common issue is loose stools when starting at full dose — which is why easing in matters. The considerations worth raising with your vet: ashwagandha can affect thyroid hormone levels, and hypothyroidism is common in dogs; turmeric may add to bleeding risk before surgery; and canine evidence for ashwagandha and ginseng is limited compared with the human research.
Yes — particularly if your dog takes any medication. Thyroid medication is the clearest example, but your vet should know about anything you are adding to the bowl. It is a short conversation and it is the step most likely to prevent a problem. If your dog is pregnant, nursing, a puppy, or due surgery, ask first without exception.
No. Some pages selling this product make that claim and it is not supportable — no supplement has been shown to extend canine lifespan, and none may claim to. What good nutrition can plausibly support is comfort, mobility, digestion and coat condition. For an ageing dog that is a worthwhile goal without inflating it into something bigger.
Coat condition is usually first, at around three to six weeks, and it is the easiest change to verify — photograph your dog on day one in the same light and compare. Joint comfort in an older dog takes longer, often 8 to 12 weeks. Day-to-day changes are gradual enough to miss without a reference point.
It is sold in multi-bottle bundles rather than singles, with the per-bottle price falling as the bundle grows — from around $59 on the 3-bottle package down to roughly $39 on the largest. The 3 and 6-bottle packages include two free bonus guides. One-time payments, no subscription. Confirm current pricing and the guarantee terms at checkout.
No, and no pet supplement is. Supplements for animals are not subject to pre-market approval any more than human ones are. The quality marker worth looking for in this category is the NASC Quality Seal — the National Animal Supplement Council audits its members and requires adverse event reporting, which is a meaningful standard in an otherwise lightly regulated space.
This is formulated and dosed for dogs, and some pages loosely suggest it suits cats too. Do not assume that. Cats metabolise several compounds very differently from dogs and are considerably more sensitive to certain botanicals and essential oils. Ask your vet before giving any dog product to a cat.
Promptly, if your dog has sudden weight loss or gain, noticeably increased thirst, rapid-onset lethargy, persistent vomiting or diarrhoea, blood in either, a new lump, laboured breathing, or sudden lameness. Hypothyroidism, Cushing's disease, kidney disease and arthritis all look like ordinary ageing at first, and all are managed better when found early.

The four things that decide it, side by side.
Liquid into the bowl. No pills to hide, no wrestling. With dogs the supplement that gets eaten is the one that works.
Bone broth collagen and turmeric — the most defensible combination here for an older, stiffer dog.
Amounts are mostly undisclosed, and canine evidence for ashwagandha and ginseng is thin compared with the human data.
Talk to your vet. Ashwagandha affects thyroid levels and hypothyroidism is common in dogs.
The verdict — 4.8/5: a practical, well-formatted supplement for a healthy older dog, and the format deserves genuine credit — liquid into food removes the single biggest reason dog supplements end up unused in a cupboard. Bone broth collagen and turmeric are the right choices for joint comfort and coat condition, and both are plausible at the amounts a 60 ml bottle can carry. It loses marks for mostly undisclosed amounts, for botanicals whose canine evidence lags well behind their human research, and for marketing that claims it can add years to a dog's life when nothing has been shown to do that. Worth trying if your vet has ruled out an underlying condition, you dose by weight, and you expect a more comfortable dog rather than a younger one. And if the change you have noticed came on quickly, see the vet before you order anything.
