1The right ingredients

Eight active ingredients in one hip and joint formula: glucosamine, MSM, chondroitin, green-lipped mussel, hyaluronic acid, vitamin C, omega-3s and yucca. Every ingredient is listed so you can see what goes into their daily chew.

2The right concentrations

The same eight-ingredient formula is used for every dog size. Choose 0–16 kg for 1 chew daily, 16–29 kg for 2 chews daily, or 30 kg+ for 3 chews daily.

3The right blend

A soft chew brings the full ingredient line-up into a single daily serving. Combine it with an appropriate diet, regular movement and your vet’s advice for a joint care routine that fits your dog.

What you can
count on

The Mr. Wuff Standard

Our approach has three parts: the ingredients, their amounts, and the complete blend. Explore our formula and see the information behind each daily serving.

Active ingredient amounts

See each active ingredient in milligrams in the product details. The table updates when you change your dog’s weight. Small and medium chews contain 731 mg of total actives per chew; the large formula contains 1,997 mg per chew.

Complete ingredient information

Our ingredient glossary includes active and inactive ingredients. The formula contains shellfish, fish, pork and milk ingredients. Check the full list if your dog has sensitivities.

A serving for their size

Choose from three weight ranges, all in kg: 0–16 kg, 16–29 kg and 30 kg+. Your selection updates the daily serving and plan prices. Follow the directions on the jar and ask your vet if you are unsure about your dog’s serving.

Pork liver flavor

Each serving comes in a soft chew with pork liver flavor. Give the daily amount shown for your dog’s weight and store the closed jar out of reach of pets and children.

Flexible refill options

A closer look at ingredient research

Joint supplement ingredients have been studied in dogs. Explore the original studies and what they can, and cannot, tell us about a daily joint routine.

Roush et al. · JAVMA · 2010

Fish oil and mobility

A randomized, blinded trial followed 127 dogs with osteoarthritis for 24 weeks. Dogs eating a food enriched with fish oil showed improvements in some owner-reported activities. The study tested a complete food with its own fatty acid concentrations.

McCarthy et al. · Veterinary Journal · 2007

Glucosamine and chondroitin

A small, blinded trial compared a glucosamine/chondroitin supplement with carprofen. Some clinical scores improved by day 70 in the supplement group. Evidence for these ingredients is mixed, and the tested supplement and doses differ from our chews.

Read the study

These studies tested different foods or supplements, not Mr. Wuff chews. Ingredients, doses and study conditions differ, so their results do not establish that our formula will produce the same effects. Joint supplements do not replace veterinary assessment or treatment.
