Lucy — from brace and dog lift to walking freely
A bad ACL tear left Lucy unable to walk without a brace. Surgery seemed like the only option, until her vet recommended FlexPet. She did not have surgery.

Jimmy — the old boy found his zoomies again
An older dog slowing down on walks. A few weeks of FlexPet every morning, consistently. You can see the rest.
What's insideMost joint chews stop at glucosamine.
Most joint chews stop at glucosamine.
FlexPet doesn't.
FlexPet is built around CM8® (cetyl myristoleate), a fatty-acid compound discovered by NIH researcher Dr. Harry Diehl, combined with five ingredients that support joint lubrication, cushioning and everyday comfort.
CM8® — 500 mg
The patented ingredient FlexPet is known for. No other pet supplement has it.
Glucosamine + MSM
The joint-cushioning basics, at real doses rather than trace amounts.
Collagen Type II + Bromelain
Support for cartilage and the tissue around the joint.
Digestive enzymes
Help your dog actually absorb what's in the chew.
How much does your dog need?
Each pouch has 60 soft chews. Dogs love the bacon-flavor chew, so most owners give it like a treat.
| Dog's weight | Chews per day | 90-day supply |
|---|---|---|
| Under 25 lbs | ½ chew | 1 pouch (lasts ~4 months) |
| 25–50 lbs | 1 chew | 2 pouches (lasts ~4 months) |
| 50–75 lbs | 2 chews | 3 pouches |
| 75–100 lbs | 3 chews | 4–5 pouches |
| Over 100 lbs | 4 chews | 6 pouches |
Dogs with a more severe joint condition may take one extra chew per day for the first two weeks. Safe to give alongside other medications. Human-grade ingredients, made in the USA in an FDA-regulated facility.

"My Bukka started limping at 14 years. I put her on FlexPet and our walks continued until she turned 18. The best part was I didn't have to disguise the tablet. She took them like a treat."

90DAY GUARANTEE
Skeptics welcome.

Good to know
Questions owners ask
How soon will I see a difference?
Most owners notice a change in how their dog gets up, climbs stairs or handles walks within 3–6 weeks of daily use. That's why the guarantee is 90 days: enough time to know.
Will my dog eat it?
They're bacon-flavored soft chews, so most dogs take them like a treat. Small dogs get half a chew, which breaks easily.
Is it safe with my dog's other medications?
FlexPet is made from human-grade ingredients and is safe to use alongside other medications. If your dog is under treatment, your vet will be glad to review the ingredient list.
Is this a subscription?
No. This is a one-time purchase. If you want it delivered automatically later, you can choose that at checkout or anytime after — never by default.
How does the guarantee work?
Use it for up to 90 days. If you're not happy, contact us at 1-800-END-PAIN or reply to your order email and we'll refund the order. Returns are free.
