Selling Out Fast
Real liquid collagen can’t be churned out like bargain-bin pills and chews — small batches mean we run dry quickly. The Summer Sale pricing is live, but only while this batch lasts.
Heads up: we only sell direct. Don’t trust the knock-offs on Amazon or eBay.
60-Day Guarantee
You’re covered by a full 60-day money-back promise.
If you haven’t seen a real difference in your dog’s scratching, hot spots, ear trouble, paw-licking or coat inside 60 days, send us one email and we’ll refund you in full — no hoops to jump through.
We can stand behind that because this works on the actual problem — a broken skin barrier — instead of muting the symptoms. If it doesn’t deliver for your dog, it’s on us, not you.
The Science Behind It
Underneath your dog’s coat is a protective barrier built largely from collagen — and it’s wearing down quicker than most owners realise.
From around age 2, dogs shed roughly 7–10% of their collagen every year. Genetics, relentless scratching, rounds of antibiotics and a poor diet all speed that up — which is why plenty of two- and three-year-olds are already battling skin issues.
As that collagen thins out, tiny gaps open up. Allergens slip through and reach deep. The immune system overreacts — and that’s the non-stop itch, the hot spots, the scratching that never quits.
Apoquel and Cytopoint quiet the symptoms — but they leave the barrier exactly as broken as they found it. That’s why the relief never sticks.
Pluto rebuilds the barrier itself: all three collagen types (I, II & III) in a liquid your dog absorbs at up to 98%, plus MSM to take the edge off the itch fast and Hyaluronic Acid to rehydrate and mend damaged tissue.
This isn’t about hiding the symptoms. It’s about repairing what’s underneath them.
Dosage & How To Use
Add it to food once a day. There’s no strong taste, so most dogs never clock it’s there.
How much to give, by weight:
- Under 25 lbs: 1 mL daily — a bottle lasts roughly 2 months
- 25–75 lbs: 2 mL daily — a bottle lasts about a month
- Over 75 lbs: 3 mL daily — a bottle lasts around 3 weeks
The barrier needs a steady supply of collagen to hold strong, so keep it going — stop, and the symptoms can creep back.
On the fence? Grab a single bottle and let the 60-day guarantee do the deciding.
How quickly will I see results?
Most dogs turn a corner inside 2–4 weeks — usually less scratching and noticeably calmer skin first. Some owners spot a change even sooner.
For the deeper stuff — stubborn hot spots, repeat ear infections, severe allergies — a full barrier rebuild generally lands around the 5–8 week mark.
Itching, hot spots, ear flare-ups, paw-licking — they all trace back to the same worn-down barrier. So as it repairs, they tend to ease off together.
And it’s rarely just the itch that shifts. Owners keep telling us the coat fills back in thicker and glossier, the energy returns, the play comes back, the nights get quieter. The dog you had before the allergies took over — that dog is still in there, under the damaged barrier.
Collagen drains away a little more every year. Keeping up the daily dose keeps the barrier solid, the allergens locked out, and your dog genuinely thriving — not just white-knuckling it through allergy season.
What’s in every serving / Ingredients?
Hydrolyzed Collagen Peptides (Types I & III) — 900mg
The backbone of barrier repair. Type I rebuilds the protective layer that keeps allergens out; Type III mends damaged tissue and helps close up hot spots, raw patches and scratched skin.
UC-II (Type II Collagen) — 40mg
Dials down the body-wide inflammation that fuels the constant itch. A clinically studied dose shown to settle inflammatory pathways throughout the body.
MSM — 400mg
A strong anti-inflammatory that eases itch and discomfort while the collagen does its rebuilding — so there’s relief during the repair, not just after it.
Hyaluronic Acid — 50mg
Holds moisture in the healing skin, keeping it supple and pliable. Dry skin mends slowly — HA keeps the repair moving.
Vitamin C — 50mg
The cofactor collagen synthesis can’t run without — it helps your dog’s body build and repair its own collagen properly.
Natural Bacon Flavor — 150mg
Turns dosing into the easiest part of the day — dogs read it as a treat, not a supplement.
Real results from real dog owners
Three different problems. One bottle. From people who’d already tried everything else.
The 3am scratching finally stopped.
Two years on Apoquel and she was still waking the house at 3am, going at her belly. We’d cycled through every shampoo and grain-free food going. Tried Pluto almost on a dare — within a fortnight the scratching had nearly vanished. Her skin’s healing and she’s finally sleeping the night through. So are we.

He’s quit chewing his paws raw.
With Cytopoint we’d get a few good weeks, then straight back to the vet. The licking was constant — his paws stained and swollen between the toes. Three weeks on Pluto and the licking just stopped. The staining’s fading and the skin between his pads is actually knitting back together. First time in two years.

Not one new hot spot since week two.
Every summer it was the same loop — hot spot, antibiotics, cone, repeat. Started this in spring without much hope. We’re deep into summer now and his coat is clear. Not a single new hot spot. The vet actually asked what we’d done differently.

EXPERT RECOMMENDATIONS

I just wish I’d had it sooner
Most collagen products are under-dosed chews padded out with fillers. This one’s actually formulated properly — Types I, II and III, in a liquid dogs genuinely absorb. I’ve had chronic allergy patients who’d tried the lot finally improve within 4–6 weeks on it. Calmer skin, cleaner ears, a thicker coat. It’s the one supplement I recommend without hesitating.

Honestly, it caught me off guard
I came in cynical — another supplement promising the world for itchy dogs. But the research on barrier depletion holds up, and the absorption you get from a liquid is real. I started trialling it on my hardest cases, dogs maxed out on Apoquel and still scratching. The skin changes were visible. The coat filled back in. A few owners even mentioned their dog’s digestion settled — which I hadn’t seen coming.

More than 50,000 dogs now live with a stronger skin barrier thanks to Pluto Advanced Liquid Collagen — finally off the merry-go-round of chronic scratching, hot spots and ear infections. We don’t paper over symptoms. We rebuild the structure underneath.
QUESTIONS? WE’VE GOT ANSWERS.
So how does it actually work?
Your dog’s skin barrier is built from collagen. As it depletes, gaps open and allergens push through — driving the relentless itch, the hot spots, the infections. Pluto delivers all three collagen types in a fast-absorbing liquid (up to 98%) to rebuild that barrier from within, with MSM and Hyaluronic Acid for relief while it heals.
How is this different from Apoquel or Cytopoint?
Apoquel and Cytopoint switch off the itch signal but leave the broken barrier untouched, so the relief fades and the symptoms return. Pluto rebuilds the structure itself, so the improvement lasts.
Why a liquid instead of chews or pills?
Chews and powders are heat-processed, which destroys up to 80% of the collagen, and most are loaded with fillers. A cold-pressed liquid is absorbed at up to 98% and actually reaches the barrier — and it just mixes into food.
How soon will I see a difference?
Most dogs improve within 2–4 weeks. Deeper issues — chronic hot spots, recurring ear infections, severe allergies — usually take 5–8 weeks for a full barrier rebuild.
Is it safe?
Yes. It’s 100% natural, non-GMO, made in a GMP-certified facility and third-party tested for purity and potency. Safe for daily long-term use, and for every breed and age.
Can I use it with my dog’s current medications?
Yes. It’s safe with Apoquel, Cytopoint and steroids. Many owners stay on their meds for the first 4–6 weeks while the barrier rebuilds, then taper off with their vet.
How much do I give?
Stir it into food once a day. Under 25 lbs: 1 mL. 25–75 lbs: 2 mL. Over 75 lbs: 3 mL.
What if it doesn’t work for my dog?
You’re covered by the 60-day money-back guarantee. No real improvement within 60 days? Email us for a full refund — even if the bottle’s empty. No questions.
Why haven’t I come across this before?
Real liquid collagen can’t be mass-produced like cheap pills and chews, so it’s never been the high-volume product the big brands push. Most owners only stumble on it after everything else has let them down.
Does it contain chicken?
No. Chicken is a leading canine allergen. We use hypoallergenic marine collagen instead — up to 98% absorption, with all three collagen types the barrier is made from.
