Honest feedback from the furry friends and humans who know us best
Made with only 6 essential active ingredients.
Glucosamine Hydrochloride, a natural compound made by the body, helps maintain healthy cartilage and promotes comfortable movement. It assists in joint lubrication and supports strong, flexible connective tissues.
Methylsulfonylmethane (MSM) is a natural antioxidant that supports a normal inflammatory response and helps maintain comfortable movement in the hips, joints, and muscles of dogs.
Chondroitin helps cushion and protect joints by maintaining water and elasticity in cartilage. It also helps maintain cartilage integrity over time to support long-term mobility.
Bone Broth provides natural collagen, amino acids, and minerals that help strengthen cartilage, nourish connective tissue, and promote smoother joint movement.
Boswellia is a powerful plant extract with natural antioxidant properties. It helps support a normal inflammatory response, promote comfortable movement, and support overall joint comfort.
UC-II® Collagen is a patented form of type II collagen clinically shown to support joint health. It works with the immune system to help maintain healthy cartilage, support everyday comfort, and promote flexibility.
Comprehensive nutrition made simple, effective, and clean for all dogs.

Yes! Our Advanced Hip & Joint supplement was formulated to be safely taken alongside our Daily Multivitamin. In fact, they complement each other- the multivitamin covers your dog’s daily nutritional needs, while the supplement provides advanced hip & joint support. For the best overall health benefits, we recommend using them together.
MULTIFLEX™ is suitable for dogs of all ages and breeds. However, we do recommend dogs begin to incorporate the powder into their daily routine starting at an age of 6 months or older.
Most pet supplements from other brands contain palm oil, fillers, artificial flavoring, preservatives, etc. At Dog is Human, we’re raising the standards of pet health by only using the highest quality human-grade ingredients, which is what our best friends deserve.
The benefits most pet parents notice—easier movement, more flexibility, and more energy—are just the bonus on top of supporting their long-term joint health. When given consistently every day, most dogs begin to show positive changes within 6–8 weeks.
There are 30 Packets in each box, which is a 2 month supply for Small Dogs (0-25 lbs) or 1 month supply for Medium and Large Dogs (25+ lbs).
Simply sprinkle the recommended daily amount over your dog’s food. Most dogs enjoy it and won’t even notice it’s there.
In the event that your dog accidentally consumes significantly more than the daily recommended dose, consult your vet for advice.
