Liquid marine collagen for dogs
The scratching was never the problem.
Shampoos wash the surface. Pills quiet the alarm. Neither rebuilds the barrier that let it all in. One pump of Bloom Triple Collagen on dinner does.





Start where your dog actually is
Not sure where to start?
Four ways this usually shows up. Pick the one that sounds like your house.
It starts at night
Scratching, licking or shaking that wakes the house between midnight and 4am.
It is the feet
Chewing, orange staining up the front of the paw, fur worn away between the toes.
It is the belly and the coat
Pink or bald patches, thin fur over the flanks, skin that flakes when you part it.
Nothing has held
Apoquel, Cytopoint, the prescription food — each one worked, then stopped.
Why we exist
The pet aisle sells you the wrong half.
Every shelf in it works on the surface or on the signal. Shampoos strip what is already on the skin. Sprays cool it. Chews and tablets go to the immune system and tell it to stop shouting. All of that is real, and none of it puts anything back.
Underneath is a wall. Skin is built out of collagen, and a dog makes less of it every year from about two years old. A thinner wall lets more through — which is why the thing that worked in March is not working by June.
BloomPet does one thing, and it is the half nobody was selling. It puts the collagen back.

What is actually in the bottle
Four ingredients. Nothing to pad it out.

100% deep-sea cod
Cold-water marine collagen, hydrolysed small enough to absorb. No chicken, no beef, no pork — the three proteins itchy dogs most often react to.

Collagen I & III
The two types skin is mostly built from. One for structure, one for repair. This is the part nothing else in the cupboard is doing.

Hyaluronic acid
Sits underneath and holds water in. Dry skin cracks and lets more through; hydrated skin is a better wall.

Glucosamine
In every pump, for the joints they use all day. The one part of this that has nothing to do with skin.
What owners report
Skin is slow. That is the point.
If something fixes an itch in three days it is switching off a signal, not rebuilding a barrier — and it comes back when you stop.
One pump on dinner
Over whatever they already eat. Wet, dry or raw — it does not matter.
The nights go first
Most owners notice the 2am scratching settling before they notice anything on the skin.
Skin comes back up
Part the coat and it stops looking thin and papery. Paw chewing usually eases here.
The coat fills in
Fur is last, always. It comes back thickest at the flanks and the back legs.
Sent in by owners, unedited
Six to eight weeks apart. Nothing else changed.


She was pink and bald from her chest to her back legs and I’d stopped taking photos of her.


I thought the orange colour was dirt for two years. It’s saliva. He stopped, and the white came back.


Both ears were raw inside. It is the quiet I noticed before anything else.
Not all collagen is the same
The source decides whether it works.

The whole routine
Four steps. One is taking a photo.
One pump on dinner
Straight over whatever they already eat. No pill to hide, no powder to stir in.
Every day, same time
It works by accumulating. The odd missed day is fine; a missed fortnight is not.
Keep doing what your vet said
Nothing here replaces a prescription. Add it on top and let your vet decide the rest.

One now, one at week eight. Skin changes too slowly to notice from memory.
The offer, plainly
Ninety days to change your mind.
You have already paid for things that stopped working. We are not asking you to gamble again. Feed it for ninety days — long enough for skin to actually turn over. If your dog is no better, tell us and we refund you.
You are not deciding whether this works. You are deciding whether to find out.

What owners tell us.
“The nights went quiet first”
Nine years of this and I had stopped expecting anything. Four weeks in she slept through, and I noticed because the house was too quiet.
“His belly isn’t pink anymore”
He was raw from his chest to his back legs. I did not believe a liquid on his food would touch it. It took about six weeks.
“The fur came back thickest at the flanks”
Scratching settled first, which I almost missed. The coat took another month but it came back in properly.
“She stopped chewing her feet”
The orange staining on her paws I assumed was dirt. It is saliva. Once she stopped, the white came back on its own.
“Ten years old and finally settled”
At his age I was told to manage it, not fix it. He is not a puppy again but he is not miserable either.
“We were on the second round of steroids”
I kept giving what the vet prescribed and added this on top, like it says. The difference showed up in the weeks after the course ended, which is usually when he crashes.
Questions owners actually ask.
How long before I see anything?
Most owners notice the scratching settling somewhere between week three and week six, and the coat filling in between week six and week eight. If something fixes an itch in three days it is switching off a signal, not rebuilding skin — and it comes back when you stop.
My dog is on Apoquel. Can I give both?
Yes, and keep giving whatever your vet prescribed — that is their call, not ours. Those medicines interrupt the itch signal. This works on the barrier underneath it. They are doing different jobs.
Why cod and not chicken collagen?
Chicken is one of the proteins itchy dogs most commonly react to, so a chicken-based supplement can work against the thing you bought it for. Ours is 100% deep-sea cod, with no beef or pork either.
My dog is fussy. Will they notice it?
It is a single pump of liquid over food, not a pill to hide or a powder to stir in. Most dogs finish the bowl without registering it.
How long does a bottle last?
One pump a day. Dose is by weight, so bigger dogs go through it faster — the chart is on the label.
What if it does nothing?
Then you tell us inside ninety days and we refund you. That is the whole point of the guarantee.

Skin changes too slowly to notice from memory, which is why so many owners give up on the thing that was working. Ninety days, one pump a day, our money back if nothing changes.
