Approach to Joint Health

Our veterinary team created MULTIFLEX™ with six key ingredients to keep senior dogs mobile and comfortable long term.

Daily Packet for Lasting

Hip & Joint Health

  • WEEK 1-2

    Early relief begins – stiffness starts to ease, and your senior dog shows less hesitation when getting up or lying down

  • WEEK 3-4

    Daily walks, climbing stairs, and playtime feel smoother and more natural as joint discomfort and soreness fades

  • WEEK 5-7

    Flexibility improves — your older pup shows more comfort moving and a renewed interest in activity.

  • WEEK 8

    Long-term relief takes hold, supporting aging joints so your dog stays active & comfortable in their golden years.

Formulated and Praised by Leading Vets

The Formulation

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 helps reduce inflammation, stiffness, and hip, joint, and muscle pain in dogs.

Chondroitin helps cushion and protect joints by maintaining water and elasticity in cartilage. It also slows cartilage breakdown 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 anti-inflammatory properties. It helps reduce stiffness, ease swelling, 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 protect cartilage, reduce discomfort, and enhance flexibility.

We Want You To Question

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 dogs feel—less stiffness, more flexibility, and renewed energy—are just the bonus on top of supporting their long-term joint health. When given consistently every day, most dogs begin to notice 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.
