I have a geriatric (approx 15-17 years old) shepherd mix. So, age along with being a survivor of a (bad) hit-and-run accident (has bone plates with pins & screws on both sides (hips) have begun to affect her mobility/energy.
I noticed results within the first couple of days.
I do wish however, there were vegan, cruelty-free & "palm free" (deforestation/orangutan) alternative for this kind of supplement.
