Hi there!
In a 2018 study, researchers from the College of Veterinary Medicine, Cornell University concluded that
2mg CBD/kg, twice daily can help increase comfort and activity in dogs with osteoarthritis.
That works out to about:
1mg of CBD per every pound, twice daily.
So a 16lb dog would take about 16mg of CBD twice daily.
I hope this helps!
