I'd tried everything for my dog's complicated skin: switching foods 100 times, Cytopoint injections, and every medication under the sun, including immune-suppressing drugs. When I came across this, I didn't have high hopes, but I figured anything was worth a shot. I'm so incredibly grateful I ordered it. My dog is a puppy again. The redness, constant itching, recurring ear infections, elephant skin, flaking and hair loss all cleared up in just 3 months. He's 9 years old and hadn't played in at least 3 years because he was so uncomfortable. Now he's running, playing and happy. Trust me, I read these reviews and thought they had to be paid or exaggerated. They're not. It started helping within a few days, and it gave me my dog back. I'm forever grateful, and so is my boy. Thank you!

Why the itch keeps coming back
Your dog’s skin barrier is made of collagen
It seals the skin so allergens stay on the surface.
Dogs lose 7 to 10% of it every year after age 2
When gaps open up in the barrier, allergens get in and the immune system overreacts. That's what causes the itch.
Medication masks it. Collagen rebuilds it.
Apoquel and Cytopoint calm the itch, but Pet Thrive rebuilds the barrier so the itch stops coming back.

I started using this after trying several multivitamins that claimed to help but did nothing. In less than a week, the scratching, licking and chewing stopped completely. I'm so glad I found Pet Thrive Liquid Collagen. Thank you so much!
My dogs were on Apoquel, Cytopoint, Benadryl and more for YEARS. After just one month on the collagen, they're off all their medications, all their hair has grown back, the paw licking has nearly stopped, and they're so much happier. This product has been a lifesaver for us, and we're so grateful.
I have two dogs, an Australian Shepherd and a Lab cross. Both started itching after a flea infestation, and the itch never went away. I saw an ad for Pet Thrive and decided to try it. We’re now on our second set of bottles, and the itching has almost completely stopped. Thank you. It really does work.
I purchased this product three months ago and I can't believe the difference in my Cocker baby. She is so much better. Far less scratching, her paws are clearing up, ear infections seem to have subsided. She is much happier and our household is so much calmer. Thank you for all the research, time and effort that has gone into this product. Karmins mom!
I have written a review a few days ago and can give an update Holly only licked her paws once yesterday l was always dubious about ordering on line this product is amazing wish I had bought it earlier.
I almost didn't buy this product for my baby, Sasha. I just adopted her earlier this year and she was very itchy and her skin was irritated. I had tried collagen before for one of my other dogs and it didn't help him at all. However, something in me said to try this product as I read how this product is made differently from the other collagen supplements out there. I am happy to report that this is working for Sasha!! She is no longer scratching herself or licking her feet. Thank YOU!!!
We have been struggling for about 2 years Itchy paws constant licking poor nights sleep horrible yeasty smell. Vet’s prescribed steroids, cytopoint and ear cleaners. I saw this ad and was dubious but thought i would give it a try. Started slowly as Ruby has a sensitive gut. The delivery was taking ages so i emailed and got a reply straight away, the product arrived a few days later. So far so good been using it for a week ….i can see a difference in her coat already and last night, the first night in a long long time …. NO ITCHING … Very happy dog and mum will carry on with the product
I’ll admit I was skeptical. Apoquel and the injections didn’t really seem to help my dog. He itched a lot, he lost a lot of hair. Decided to try it. Two months in almost all his hair is back. His itching has almost stopped completely! Highly recommend!
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!!!
What an amazing product. We tried everything for our boys skin problems he would never fully heal. Two weeks on this product and his skin is perfect and his fur is thick and healthy too.
My dog nova has only been on this for 8 days and the difference I’ve seen in her already is insane! She’s a 7 year old pittie with terrible allergies & we’ve tried everything. Within days she is back to playing like a puppy again and her skin and coat feel super soft already. We have very high hopes to see how she continues to improve as it builds her skin barrier back up!
I have 3 big dogs. We started using this over a month ago and the lack of scratching was the first thing I noticed-their ears are no longer super red and inflamed inside and the head shaking is a thing of the past. Love this product and it is so simple to just add to their feed and they gobble away.
100% satisfied with Pet Thrive. My Labrador Sampson has suffered from allergies for a couple years. Numerous medications and trips to his vet, nothing worked. He picked his paws/ body amd scratched so much that he had scabs all over his body. I came across Pet Thrive and researched liquid collagen for dogs. After talking to his vet, we decided to give it a try. I ordered from the Pet Thrive website and got the buy 2/get 1 free. The difference is unbelievable. Sampson has been on the collagen going on 3 months and the scratching and licking has greatly reduced to where he almost doesn't scratch anymore. I put the collagen in his food with some broth and he eats it right up. Don't be fooled by the fake collagen on the market. We also give Sampson a bath at least once a month and we wipe him down with a damp cloth after being outside which helps remove what he picks up from the grass. Excellent product.
One of our dogs was scratching almost continuously and was getting quite distressed, with sore areas where she’d nibbled herself. We’d tried changing food, different shampoos, oils, but nothing had any lasting effect. We tried this, and although it took a couple of months and we were starting to wonder if it would help her, it has now completely cleared up her problem. No more scratching, no more sore areas, and instead a lovely glossy coat, and a happier dog! We also give it to two other of our dogs who were a little itchy, and it’s been just as successful, and we saw results after only about three or four weeks with them. Each of the dogs seems to like the flavour and eats enthusiastically. I’d thoroughly recommend this product. It’s been a complete game changer for us.
I started Pet Thrive liquid collagen in May. It’s now three months later and I am so very pleased with how my dogs skin is looking and feeling . No more itching and no more scabbing of his under belly and under arms . I have tried so many things to help him. He is a large breed dog and his allergy medicine is expensive. I’m going to try to take him off the allergy medicine all together. I’ll write about it here when I do try that. I love spreading good news to try to help people who love their pets like I do!! i bought the 3 bottles at once and have it on auto ship. It’s easy to get on and delay it if necessary! Sincerely, Kim and I”Benny”
Frequently Asked Questions
How does this actually work?
Your dog's skin has a protective barrier made of collagen, and it keeps allergens on the surface where they belong. Dogs lose 7–10% of their collagen every year as they age. Once that barrier breaks down, allergens get deep into the skin and set off the immune response behind the scratching, hot spots and ear infections. Our liquid collagen gives your dog's body the building blocks it needs to rebuild that barrier from the inside.
How is this different from Apoquel or Cytopoint?
Apoquel and Cytopoint work by suppressing your dog's immune response to allergens. They stop the symptoms, but they don't fix the underlying cause. Our collagen rebuilds the skin barrier, so allergens can't get as deep into the skin to begin with. Many customers give collagen alongside their dog's medication at first, then cut back on the medication over time as the barrier gets stronger.
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. It's made of natural building blocks your dog's body already uses. It doesn't suppress the immune system, and there are no drug interactions to worry about. It comes from wild-caught fish and is made in a cGMP-certified facility. It's safe to give every day for the long term.
Can I use this with my dog's current medications?
Yes. Many customers start their dog on collagen while the dog is still taking Apoquel or Cytopoint. As the skin barrier rebuilds and symptoms ease, they work with their vet on whether the medication can be reduced. It won't interfere with other treatments.
How much do I give?
Give 1–3ml a day, depending on your dog's weight. One full dropper is 1ml, and the bottle has the instructions. It's easy to adjust the amount for small or large dogs.
What if it doesn't work for my dog?
Every order comes with our 30-Day Money-Back Guarantee. If your dog’s skin, coat and comfort haven’t really improved after 30 days, just email us and we’ll look at your refund. We can offer this because tens of thousands of dog parents have already seen the results. And 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 among the most common food allergens for dogs, so including either in an allergy product could make the itching worse. Our collagen is marine collagen from wild-caught fish and contains no chicken, beef, poultry or dairy. It’s hypoallergenic, absorbs at up to 98%, and provides all three collagen types that make up the skin barrier.
