Going viral broke our stock maths. In stock today, that's the most we can promise. Subscribers always get theirs first.
Per 2 ml: Collagen Peptides, Types I & III, 800 mg. Cold pressed and hydrolysed: no heat treatment, pre-broken into pieces small enough to absorb. This is the mortar of the skin's brick wall: Type I re-seals the outer wall; Type III repairs the damaged tissue under hot spots and raw patches.
Undenatured Type II Collagen, 40 mg. Calms the body-wide overreaction that drives constant itching, at the dose used in the research.
MSM, 400 mg. A natural itch-soother that keeps your dog comfortable while the wall rebuilds.
Hyaluronic acid, 50 mg. Holds water in healing skin. Dry skin repairs slowly; hydrated skin repairs faster.
Vitamin C, 50 mg. The body can't build collagen without it.
Natural bacon flavour. Turns medicine time into treat time.
Squeeze it over food once a day. The natural bacon flavour does the convincing.
Dose depends on your dog's weight:
Under 4.5 kg: 1.0 ml a day, a bottle lasts 60 days
4.5–11 kg: 1.5 ml a day, a bottle lasts 40 days
11–23 kg: 2.0 ml a day, a bottle lasts 30 days
Over 23 kg: 3.0 ml a day, a bottle lasts 20 days
The barrier needs a steady supply of collagen to stay sealed.
Picture your dog's skin as a brick wall. Collagen is the mortar holding it together. From around age two, a dog's body makes roughly 7–10% less collagen each year, and genetics, constant scratching, antibiotics and a poor diet wear the mortar down even faster. That's why some dogs are only 3 and already itchy.
As the mortar thins, the wall develops cracks. Pollen, dust and grass slip through, the immune system panics, and what you see is the scratching, the hot spots, the ear infections that keep coming back.
Allergy medicines tell the immune system to calm down. That helps. But the cracks are still there, which is why the itch returns the moment the drug wears off.
These drops give the body the raw material to re-mortar the wall: all three collagen types, in liquid form so it actually absorbs. MSM eases the itch while the wall repairs. Hyaluronic acid stops healing skin from drying out.
You're not silencing the alarm, you're fixing what set it off.
Most owners notice the first shift between weeks 2 and 4: less scratching, calmer skin, quieter nights.
Deeper problems like recurring hot spots, ear infections and chewed-raw paws need the tissue underneath to close, which usually lands between weeks 5 and 8.
A full barrier rebuild takes about 12 weeks. And because a dog's own collagen production keeps falling every year, owners keep a daily maintenance dose going after that: it's what keeps the wall sealed. That's also why improvements compound over months instead of wearing off between doses like medication.
Give it a fair run for 90 days. If your dog's scratching, licking, hot spots or ear trouble haven't clearly improved, email us and we refund the full price. Order enough for 90 days based on your dog's size (bigger dogs use more per day): that's enough to cover the full 12-week barrier rebuild, not just the first signs.
Safe with Apoquel or Cytopoint? Yes. It runs alongside allergy medication. Never stop a prescription on your own.
Any chicken in it? None. The collagen is formulated without any chicken ingredients, a top trigger for allergic dogs.
We changed foods and it didn't help. A diet swap removes one trigger from the bowl. The drops close the cracks that let the rest in.
My dog is young. If they're itchy already, the wall is already thinning. Starting early means less to repair.
Will this work on my breed? Yes. Every breed builds its skin barrier from the same collagen, so the repair works the same from Chihuahua to Great Dane. Breed only changes how fast the wall wears down: Frenchies, Staffies, Bulldogs, Westies, Goldens, Labs and GSDs wear theirs fastest, which is why they scratch the most and have the most to gain. Dosing goes by your dog's weight, not breed.
Sensitive stomach? The formula is gentle and filler-free. Start with a half dose for the first few days if you're cautious.
Where is it made? Made in the UK and the US. Ships from our UK warehouse via Royal Mail Tracked.
Owners who got here the long way: after the diets, the shampoos and the prescriptions.
Poppy, Cocker Spaniel, 4For a year that jingle was our alarm clock: 2am, scratch, scratch, scratch. We rotated three foods and two shampoos before this. Around week three on Tailsome the nights went quiet. I kept waking up anyway, waiting for it. It never came.
review by Rachel D.
Otis, Beagle, 5He licked his front paws so much we had him in baby socks around the house. Prescription worked for a stretch, wore off, repeat. Six weeks on the Tailsome drops and the socks are in a drawer. His paws look like a dog's paws again.
review by Marcus T.
Meg, Labrador, 5After every swim came the ear routine: shaking, scratching, that warm yeasty smell you could catch from the sofa. Ear drops were basically on subscription. Ten weeks in with Tailsome, she's back in the river most walks and her ears stay clean.

Runs safely alongside prescriptions. Never stop one without your vet.
Repairs raw skin
Worn thin. Skin runs out of its main building material. This restocks it, so raw patches and hot spots close.
Calms the itch
Overreacting. The immune system attacks everything that gets in. This settles it down, without switching it off.
Comfort right away
Still itchy. Repair takes weeks and the scratching is now. This soothes while the skin heals.
Locks in moisture
Drying out. Dry skin cracks, and cracks let allergens in. This holds water in, so they stay shut.
The skin barrier process
A thin protective layer seals the skin and keeps pollen, dust and grass on the outside. While the wall is whole, your dog is comfortable.
Collagen production falls as dogs age, and scratching, antibiotics and poor diet speed the loss up. The wall thins, and microscopic cracks open in it.
The immune system attacks whatever gets in. The scratching, the raw paws, the flare-ups, the ear trouble: all of it is that overreaction at work. Your dog isn't the problem; the cracks are.
Apoquel and Cytopoint quiet the immune response, but the cracks stay open, so allergens keep getting in, and the itch keeps coming back.
Feed the barrier the collagen it's made of and it repairs itself. Less scratching, softer coat, fewer flare-ups, because nothing is getting through any more.
You can run them together: they work on different problems. Medication quiets the immune response; the drops rebuild the barrier that's letting allergens in. Many owners keep the prescription at first, then talk to their vet about reducing it as the skin improves. Never stop a prescription on your own.
Barrier repair is newer research. Some vets already recommend collagen for skin, and many haven't caught up with the studies yet. Ask yours about it.
Don't judge it on the first bottle. First signs usually land between weeks 2 and 4, but the deeper repair, closed hot spots and settled ears, shows between weeks 5 and 8. Give it the full 12 weeks before you decide.
These are building blocks your dog's body already uses daily. Nothing is being suppressed. Sourced from wild-caught fish, cold pressed, made in a GMP-certified facility, third-party tested every batch. Fine for long-term daily use.
Not every itch is barrier damage. If it isn't your dog's problem, the 90-day money-back guarantee covers you.
