A 2018 meta-analysis of publications on a variety of dietary supplements for osteoarthritis in humans suggested

with glucoasamine, chondroitin, MSM and avocado soybean unsaponifiables, although they stated that there was also a need for more higher quality evidence (2).
Omega-3 Fatty Acids
The recommended d
ose is 15 mg/lb of DHA. Make sure the source is tested for heavy metals. Good sources include Grizzly Salmon Oil and Nordic Naturals, but there are others as well.
Two 2016 metastudies concluded that there is
evidence for the systemic anti-inflammatory effects
of omega-3 fatty acid supplementation (3, 4).

A supplement called ProBalance by AVN is recommended to ensure that your dog is receiving an abundance of the correct, animal-sourced amino acids.
This supplement has been designed by an independent, board-certified veterinary canine nutritionist to supply all of the essential, animal-sourced amino acids and building blocks for important nutrients, like taurine, that often are lacking in commercial dog food and homemade diets.
