The medicine stops the itch. This rebuilds her skin. If it does not work for your dog, you do not pay.
Dogs who scratch and lick lose collagen from their skin faster than their bodies can rebuild it. Collagen is what skin is made of.
Her skin is a wall made of collagen. Two kinds of it, called type one and type three. That wall keeps pollen, dust, grass and mold on the outside. Every day, the scratching knocks bricks out of that wall. Every night, her body puts a few back. Never as many as she lost.
That shortfall is The Rebuild Gap, and it gets wider every month. Raw skin itches from the damage, so she scratches more. Vets call that the itch and scratch cycle. It is still allergies. The allergy is what starts the itch. The Rebuild Gap is what keeps it going. And the older she gets, the slower she rebuilds.
Apoquel and Cytopoint stop the itch. That is all they do. They do not rebuild her skin. It is like hanging a curtain over a hole in a wall. You cannot see the hole anymore, but behind the curtain it keeps growing.
Her skin needs collagen to rebuild. Ours is liquid, with the collagen already broken down into tiny pieces. Types one and three. 900 mg in every mL. Dosed by her weight. Every single day.
Add it alongside whatever your vet has her on. Stop nothing. The medicine stops the itch. This rebuilds her skin.
Mix into food once daily. Tasteless — dogs don’t notice it.
Dosage by weight:
— Under 25 lbs: 1 mL daily — one bottle lasts about 2 months
— 25–75 lbs: 2 mL daily — one bottle lasts about 1 month
— Over 75 lbs: 3 mL daily — one bottle lasts about 3 weeks
Her skin keeps breaking down as long as she scratches, so it needs collagen every day to keep rebuilding. Do not miss a day.

Skin does not rebuild overnight. Do not expect much in the first two weeks. Keep going.
The first signs usually show around week four: a full night of sleep, less licking, less scratching.
The scratching, the paw licking and the ear infections are all her skin breaking down in different places. So as her skin rebuilds, you should see it in more than one place.
It keeps building from there. By week six to eight, look for a thicker coat, more play and quieter nights.
She will still have allergies, and she may still scratch now and then. Keep her on what her vet prescribed. The dropper is every single day, because her skin never stops needing to rebuild.
Hydrolyzed Collagen Peptides (Types I & III) – 900mg

MSM – 400mg
Helps calm the itch while her skin rebuilds.

Natural Bacon Flavor – 150mg
Makes daily dosing easy — dogs think it’s a treat, not medicine.
Is this right for my dog?
For dogs with allergies who scratch, lick their paws, get hot spots or keep getting ear infections. If the medicine helps for a while and then it all starts up again, nothing is rebuilding her skin.
Is it safe? Can I use this with Apoquel or Cytopoint?
Yes — 100% natural, non-GMO, made in a GMP-certified facility. All ingredients are third-party tested for purity and potency. Safe for daily long-term use and safe alongside medications including Apoquel, Cytopoint, and steroids. Add it alongside whatever your vet has her on. Stop nothing.
Does your Liquid Collagen contain chicken?
No. Chicken is one of the most common allergens in dogs — using it in an allergy product would risk making symptoms worse. We use marine collagen instead. It’s hypoallergenic, absorbs at up to 98%.
Why do allergy medications stop working after a few weeks?
They did not stop working. Apoquel and Cytopoint block the itch. That is all they do. They do not rebuild her skin. So the damage underneath keeps growing, and the medicine has to hold back a bigger and bigger itch. It is like a curtain over a hole in a wall. This rebuilds her skin underneath.
Will this work if food changes failed?
Yes. A new food can take away a trigger, but food is not collagen. It does not rebuild her skin. This does.
Will this work for younger dogs?
Yes. If your young dog is already scratching, her skin is already breaking down faster than she can rebuild it. The sooner her skin has collagen to rebuild with, the less it falls behind.
My dog has a sensitive stomach. Is this safe?
Yes. Our liquid formula is gentle and easy to digest. MSM and Hyaluronic Acid are both well-tolerated. Start with half dose for the first few days if concerned.
Four problems. One bottle. Hear from the people who tried everything else first.
Two years of Apoquel and she’d still wake us up at 3am clawing at her belly. Hot spots every few weeks, cone on, cone off, repeat. Tried every shampoo, every grain-free diet. Started HealthfulPetz on a whim — within two weeks the scratching had almost completely stopped. No new hot spots since. Her skin is healing and she’s sleeping through the night. So am I.
Bella 🐾 Golden RetrieverReview by Sarah K.Cytopoint would work for a few weeks then we’d be straight back to the vet. The licking was constant — his paws were stained and inflamed between the toes. Three weeks on HealthfulPetz and the licking just stopped. The staining is fading and the skin between his pads is actually healing. First time in two years.
Buddy 🐾 LabradorReview by James R.Every two weeks it was the same cycle — brown gunk, yeast smell, pulling away when I tried to clean them. Started this collagen after two years of ear drops and vet visits. Week four I cleaned his ears and the cotton pad came back white. Three months now and not a single infection. The vet said she’s never seen his ears this clean.
Charlie 🐾 Golden RetrieverReview by Linda M.What her skin is made of. The collagen her body uses to rebuild her skin.
Clinically studied to calm immune response naturally.
Helps the body turn collagen into new skin. Essential for the rebuild process.
Helps her skin hold moisture.
Better absorption = more collagen reaching her skin.
Most chews and powders are not broken down at all, and most will not tell you how much collagen is in them.
Liquid is cold-pressed — up to 98% gets absorbed and reaches her skin.
Plus, no fighting your dog to eat a chew. Just mix into food.

I was skeptical. Another supplement claiming to help allergies. But the science on barrier depletion is solid and the liquid absorption is real. I started recommending it to my toughest cases — dogs on maximum Apoquel still scratching. The skin improvements were visible. The coat came back. Several owners told me their dog’s digestion improved too. I wasn’t expecting that.
The medicine stops the itch. HealthfulPetz Liquid Collagen rebuilds her skin. One dropper on her food, every single day, alongside what her vet prescribed.
Dogs who scratch and lick lose collagen from their skin faster than their bodies can rebuild it. That is The Rebuild Gap. Liquid collagen, already broken down, gives her skin what it needs to rebuild. Read "The Science Behind It" above for the full explanation.
Apoquel and Cytopoint stop the itch. They do not rebuild her skin. Our liquid collagen does. It works alongside the medicine, not instead of it.
It has to be liquid, with the collagen already broken down into tiny pieces. A chew has to be held together with something and flavored with something. Turn the bag over and look for the collagen amount. Ours is 900 mg in every mL.
Do not expect much in the first two weeks. The first signs usually show around week four. It keeps building over the next couple of months.

Most of what you have been told is about stopping the itch. Almost nobody talks about rebuilding her skin. That is what this is for.

We started Max on this a couple months ago and truly are surprised how good his coat and skin look! He is not itching and licking like he had been. Dry skin flakes are nearly gone! If your dog has these issues, try this, it worked for Max!!!
My Lab Buddy is 6 years old. Every summer, he scratches and breaks out in hot spots. Over the years, I have tried everything and nothing worked. Then he got fleas. I treated him for that. He stopped eating so I started him on HealthfulPetz liquid collagen. Within a few days, his appetite came back. In 2 weeks, way less scratching and it literally saved his life!! Thank you for making this!
I have tried everything for my dogs complicated skin, switching food 100x, cytopoint injections, every medication under the sun including immune system blockers. I came across this and didn’t have high hopes but figured anything is worth a shot.
Let me say, I am so incredibly grateful I did order. My dog is a puppy again.
Redness, constant itching, revolving ear infections, elephant skin, flaking, hair loss, it’s all resolved in 3 short months. He is 9 years old and hasn’t played in at least 3 years because he was so uncomfortable. My dog is running, playing, and happy...
Started using this in April and very impressed.
Normally my chocolate lab would get an injection in March and then possibly again in July due to the heat and allergies. He would also be taking Apoquel all summer long. I have been very happy with this product. He has not itched or had any hotspots, even with the heat and temperatures being up to 90s in Vermont.
