Our verdict

A superfood powder for dog joints that bundles omega fatty acids, glucosamine, MSM, chondroitin and a probiotic. Dogs with food allergies should skip it, since the allergen line is long.

Overview

The Missing Link Hip and Joint plus Probiotics is a powder supplement that adds flaxseed fatty acids, glucosamine and chondroitin to a dog's meal. It also carries a prebiotic and a probiotic, and lists many inactive ingredients.

One scoopable powder covers cartilage support, fatty acids and gut bacteria, which suits owners who want to give fewer products. The limitation is allergens, with beef, fish and shellfish all named, and no feeding directions on the page.

Who it's for

Dogs that eat a mixed diet and need joint and cartilage support can have this powder mixed in with food. Dogs with food allergies, and owners who need a documented dose, should look at another product.

Pros and cons

Pros
  • Omega fatty acids from flaxseed
  • Glucosamine, MSM and chondroitin
  • Probiotic and prebiotic included
  • Powder form for mixing
Cons
  • Contains beef, fish and shellfish
  • Feeding directions not shown

Performance notes

Amounts are given per a serving of three teaspoons, so the real intake depends on how much powder a dog is fed. Joint ingredients build their effect gradually, while the probiotic and prebiotic act in the gut. The package must supply the dose by weight.
