We offer a full 60-Day Money-Back Guarantee.

If you don't see real improvement in your Frenchie's paw chewing, red belly, ear gunk, scratching or coat within 60 days, simply email us for a full refund, no questions asked.

We're confident because Koatly addresses the root cause (a broken skin barrier), not just the symptoms. But if it doesn't work for your dog, you don't pay.

Most owners see the first change at 2 to 3 weeks: less night licking, calmer skin, a belly that's less red, quieter paws. The first week or two can look like nothing is happening. That's normal; the barrier rebuilds from the inside before you see it on the outside.

Deeper problems like chronic hot spots, recurring ear infections or severe allergies usually take 6 to 8 weeks. Rust staining on the paws fades last, because the stained fur has to grow out after the licking stops.

Paw licking, red belly, ear gunk, scratching: all symptoms of the same broken barrier. As it rebuilds, they improve together. Owners tell us the coat comes back thicker, the evening paw-washing ritual gets shorter, and their dog is sleeping through the night again.

Nothing at three weeks? Check the dose against the weight table and keep going to week six. No change at 60 days, and the guarantee means you don't pay.

Your dog loses collagen every year. Daily use keeps the barrier strong and the allergens out.

Section 5

Tab title: What's in each 1 mL serving / Ingredients?

Body:

Hydrolyzed Marine Collagen (Types I & III) - 900mg
The foundation of your dog's skin barrier. Type I rebuilds the protective barrier that keeps allergens out. Type III repairs damaged tissue and heals hot spots, raw patches and chewed areas. Hydrolyzed means it's already broken down small enough to absorb, instead of being digested like food.

UC-II (Type II Collagen) - 40mg
Reduces the systemic inflammation driving the constant itch response. Clinically studied dose shown to calm inflammatory pathways throughout the body.

Omega 3 - 400mg
Powerful anti-inflammatory that reduces itch and discomfort while collagen rebuilds the barrier. Provides fast relief during the repair process. Think of it as the mortar between the bricks. On its own, fish oil is mortar with no foundation underneath. Here it works alongside the collagen that rebuilds it.

Vitamin C - 50mg
Essential for collagen synthesis. Helps your dog's body produce and repair collagen tissue effectively.

One serving on their food, once a day. Dogs think it's a treat, not medicine.

Is Koatly right for my Frenchie?
For French Bulldogs who chew their paws, have a red or raw belly, recurring ear infections or gunk, constant scratching, or thinning fur. If you've already been to the vet, tried the shots and switched the food, and it keeps coming back, their skin barrier is breaking down and needs to be rebuilt.

Isn't this just part of owning a Frenchie?
It's common in the breed, but common isn't the same as permanent. The breed's genetics make the skin barrier more fragile, which is exactly why rebuilding it matters more for a Frenchie than for most dogs. You chose a wonderful breed. Koatly just helps you give it the support its skin needs.

Is it safe? Can I give this with Apoquel or Cytopoint?
Yes. Koatly is 100% natural, non-GMO, made in a GMP-certified facility and third-party tested. Safe for daily, long-term use and safe alongside all medications, including Apoquel, Cytopoint, Zenrelia, steroids, Benadryl, Zyrtec and antibiotics. There's no drug in it, so nothing interferes. Most owners keep their dog's medication going for the first 4 to 6 weeks while the barrier rebuilds, then work with their vet on reducing it.

Does Koatly contain chicken or beef?
No. Chicken and beef are two of the most common food allergens in dogs, and especially in Frenchies, 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 absorbs at up to 98% and contains all three collagen types the skin barrier is made from. If your vet has confirmed a true fish allergy, check with them before starting.

Why do allergy medications stop working after a few weeks?
Medications suppress symptoms but don't rebuild the barrier. As it continues breaking down, symptoms return and the shots get more frequent, and more expensive. Collagen fixes the structure, so results last.

Will this work if food changes failed?
Yes. If you've changed the food three times and your Frenchie is still licking, the food probably isn't the whole story. Diet changes remove trigger proteins but don't fix the broken barrier. Collagen rebuilds it so allergens stop penetrating, whether they come from the bowl or the backyard.

Will this work for younger dogs?
Yes, and it's even more important. Half of Frenchies with allergies are showing symptoms by age 1 to 3. If your young dog is already scratching, their barrier is already damaged. Catching it early means less damage to repair, faster results, and avoiding years of expensive injections.

My dog has a sensitive stomach. Is this safe?
Yes. Koatly's liquid formula is gentle and easy to digest. Collagen peptides and Omega 3 are both well-tolerated. Start with a half dose for the first few days if concerned.

Note that the Section 5 tab title corrects your current "1mg" to "1 mL" so it matches the dropper measurements in the dosage section.

Mix into food once daily. Tasteless, so even a picky Frenchie won't notice it.

Most French Bulldogs weigh 16-28 lbs, so for most Frenchies it's 1 mL a day, and one bottle lasts about 2 months.

Full 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

Your dog's barrier needs ongoing collagen to stay strong. If you stop, symptoms can return.

Your Frenchie's skin has a protective barrier made of collagen, and in this breed it's breaking down faster than you think.

Dogs lose 7-10% of their collagen every year after age 2. Genetics, chronic scratching, antibiotics and poor diet accelerate it. French Bulldogs carry the genetic load and the tight skin folds, which is why so many are already chewing their paws raw at 2 or 3 years old.

As collagen depletes, gaps form. Allergens penetrate deep. The immune system goes into overdrive. That's the constant licking, the rust-stained paws, the raw belly and the ears that never stay clean.

Apoquel and Cytopoint suppress symptoms, but they don't rebuild the barrier. That's why the relief fades, and why so many Frenchie owners say the shot that "used to work" doesn't anymore.

Koatly rebuilds the barrier itself. All three collagen types (Types I, II & III) in liquid form for 98% absorption. Plus Omega 3 for fast itch relief and Vitamin C to help your dog's body turn that collagen into new, healthy skin tissue.
