Straight answers, in full.

All KOPO supplements are made in the USA, in a GMP-certified, FDA-registered facility in New Jersey. Every batch is third-party lab tested for purity and safety.

Yes. The formulas are designed to work together and the doses account for each other. Multivitamin + Dental Powder is the intended daily combination.

KOPO is a family-owned, founder-led company based in Parsippany, New Jersey. Founder and CEO Recep Copur entered the pet-supply industry in 2019, launched the KOPO brand in 2024 after years of reading labels the market wouldn't fix, and shipped the first two products, developed in-house and made in the USA, in September 2025. The team is deliberately small: product management, a two-person warehouse crew, and no committee between you and the jar.

Sprinkle the recommended scoops over your dog's regular food once a day and mix. Small dogs (up to 20 lbs): 1 scoop. Medium (21–50 lbs): 2 scoops. Large (over 50 lbs): 3 scoops. No pills, no hiding, no stress.

Most pet parents notice improvements, fresher breath, better appetite, softer coat, healthier stool, within 2–4 weeks of daily use. Plaque, tartar, and mobility changes typically follow at 4–8 weeks. Results vary by age, diet, and consistency.

Yes. KOPO Dental Powder and All-in-One Multivitamin Powder are both on Amazon. They are the same formulas, made in the same U.S. facility. A few things are only available when you order directly from us:

• The Complete Care Duo. Both powders as one set, with doses designed to work together. The Duo isn’t sold on Amazon, and on subscription it costs less than buying the two jars separately, here or there.
• Our lowest subscription prices, with free U.S. shipping on every order.
• Full control of your subscription. Skip, pause or cancel from your account, no phone calls.
• Direct help from the KOPO team. Questions about dosing, your dog’s size or an order come straight to us at hello@kopopet.com or 305 824 6035.
• The 66 scoops empty-jar guarantee on orders placed at kopopet.com.

Start with half the recommended scoops mixed into meals for the first 7 days, then move to the full amount. Giving it with food improves absorption and comfort. Mild, brief stool changes can happen while the probiotics settle in; if anything persists beyond a few days, pause and check with your vet.

In a cool, dry place with the lid tightly sealed. No refrigeration needed. Each jar carries a clear Best By date.

Natural, science-backed ingredients: whole-food nutrients like freeze-dried beef liver and heart, organic vegetables and berries, green-lipped mussel, salmon oil, probiotics, enzymes, and CoQ10. No artificial flavors, fillers, or unnecessary additives, and every dose is published on the label.

By design. Most dogs on commercial diets already get adequate calcium, and stacking more can cause problems, especially for large-breed puppies. Dogs on homemade diets who need calcium should have it dosed to their specific meals by a vet.

Kelp is effective against plaque, but it's also high in iodine, and unchecked iodine can stress a dog's thyroid. We cap kelp at 120 mg per scoop and build the rest of the formula from eight other ingredients, including CoQ10 and PAC-rich cranberry.

Under FTC rules, a plain Made in USA claim requires that all or virtually all ingredients and processing be of U.S. origin. Many pet brands instead print "Manufactured in USA*" with fine print admitting globally sourced ingredients. KOPO clears the real standard: made in a GMP-certified, FDA-registered New Jersey facility from U.S.-origin ingredients, with manufacturer certificates available on request.

Yes, KOPO formulas are safe for puppies 12 weeks and older. Always follow the weight-based serving chart.

Ask your veterinarian before starting. Bring the label with you — every ingredient and exact dose is printed on it, so your vet can check for interactions without guessing.

Yes, there's no chicken in either formula. The flavor base is beef liver. Both products are also grain-free and gluten-free. For beef allergies or other specific sensitivities, review the full ingredient ledger with your vet.

Kelp is effective against plaque but naturally high in iodine, and unlimited iodine can stress a dog's thyroid. KOPO caps kelp at 120 mg per scoop to keep daily iodine conservative. If your dog has a diagnosed thyroid condition or takes thyroid medication, check with your veterinarian before starting any kelp-containing product, ours included.

The formulas are built to make that hard: doses are weight-based, nutrients come from whole foods rather than synthetic megadoses, and the two products account for each other so they can be used together. Follow the serving chart, don't combine with another multivitamin, and store jars sealed and out of reach. If a dog ever eats a large quantity at once, call your veterinarian.

No. Human vitamins are dosed for humans and can contain ingredients dangerous to dogs, such as xylitol, high iron, and high vitamin D. Always use supplements formulated and dosed for dogs, and contact your veterinarian if your dog accidentally eats human vitamins.

Yes, with honest expectations. The ingredients work both on tooth surfaces and through saliva as your dog eats, making it harder for plaque bacteria to stick and multiply. Most pet parents notice fresher breath in 2 to 4 weeks and visibly less new buildup at 4 to 8 weeks. What no powder can do is remove tartar that has already hardened; that requires a veterinary cleaning. Brushing is still ideal when your dog allows it, and the powder gives you a daily baseline when he doesn't.

No. Hardened tartar can only be removed safely by a professional veterinary cleaning. The powder's job is prevention: stopping new plaque from mineralizing and protecting the results after a cleaning, at about a dollar a day versus $2,000 to 3,000 for a cleaning under anesthesia.
