Why the itch keeps coming back

  1. Your dog’s skin barrier is made of collagen

    It seals the skin and keeps allergens on the surface.

  2. Dogs lose 7 to 10% of it every year after age 2

    Gaps open up, allergens get in and the immune system overreacts. That’s the itch.

  3. Medication masks it. Collagen rebuilds it.

    Apoquel and Cytopoint calm the itch. Healthy Petz rebuilds the barrier, so it stops coming back.

    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 9years old and hasn’t played in at least 3 years because he was so uncomfortable. My dog is running, playing, and happy. Trust, I read these reviews and thought they had to be paid or exaggerated. They’re not. This gave me my dog back and started helping a few days in. I am forever grateful and so is my boy. Thank you!

    My dogs have been on Apoquel, Cytopoint, Benadryl, etc. for YEARS. After using the collagen for only a month they are off all medications, all hair has grown back, paw licking is at a minimum, and they are so much happier. This product has been a savior for us. We are so thankful.

    I have 2 dogs. An Australian shepherd and a lab cross They both developed an itch from a flea infestation which did not go away. I saw this ad from healthy petz and thought I would give it a try. I am on the second set of bottles and the itching has almost completely stopped. Thank you. It does work.

Frequently Asked Questions

How does this actually work?

Your dog's skin has a protective barrier made of collagen. This barrier keeps allergens on the surface where they belong. As dogs age, they lose 7-10% of their collagen each year. When the barrier breaks down, allergens penetrate deep and trigger the immune response — that's the scratching, hot spots, and ear infections. Our liquid collagen provides the building blocks to rebuild that barrier from within.

How is this different from Apoquel or Cytopoint?

Apoquel and Cytopoint suppress your dog's immune response to allergens. They stop the symptoms but don't fix what's causing them. Our collagen actually rebuilds the skin barrier so allergens can't penetrate as deeply in the first place. Many customers use collagen alongside their medications initially, then reduce medication over time as the barrier strengthens.

Why liquid instead of chews or pills?

Absorption. Chews and pills contain large collagen molecules that dogs can only absorb at 20-30%. Our liquid collagen is hydrolyzed — pre-broken into tiny peptides that absorb at up to 98%. Your dog actually gets the collagen instead of passing most of it through.

How long until I see results?

Most owners notice reduced scratching within 2-3 weeks. Significant skin improvement typically happens between weeks 4-8. Full barrier rebuilding takes 8-12 weeks, which is why most customers choose multi-bottle packages.

Is it safe?

Yes. These are natural building blocks your dog's body already uses. There's no immune suppression, no drug interactions to worry about. It's sourced from wild-caught fish and manufactured in a cGMP certified facility. Safe for long-term daily use.

Can I use this with my dog's current medications?

Yes. Many customers start collagen while their dog is still on Apoquel or Cytopoint. As the barrier rebuilds and symptoms improve, they work with their vet to potentially reduce medications. This doesn't interfere with other treatments.

How much do I give?

1-3ml per day based on your dog's weight. One dropper = 1ml. Instructions are on the bottle. Easy to adjust for small or large dogs.

What if it doesn't work for my dog?

We offer a full 60-Day Money-Back Guarantee. If you don't see real improvement in your dog's skin, coat and comfort within 60 days, simply email us and we'll review your refund. We're confident because tens of thousands of dog parents have seen the difference. But if it doesn't work for your dog, you don't pay.

My dog has a sensitive stomach. Is this safe?

Yes. It's a liquid, so there are no fillers, binders or chews to break down, and it goes onto food your dog already eats. It's gentle on the gut and easy to absorb. If your dog is especially sensitive, start with half the dropper for the first few days and move up to the full amount once you see it's sitting well. A soft stool in the first day or two is rare and settles on its own.

Does your Liquid Collagen contain chicken or beef?

No. Chicken and beef are two of the most common food allergens in dogs, so putting either in an allergy product would risk making the itching worse. Our collagen is marine, sourced from wild-caught fish, with no chicken, beef, poultry or dairy. It's hypoallergenic, absorbs at up to 98%, and contains all three collagen types the skin barrier is made from.
