When we received it, it appeared to have some crystallized fluid. Even after shaking well, it appeared a little “off”.I have been giving my girl 1 ml to start with even tho it calls for more according to her weight. I do notice she has stopped moaning when she moves and the first two days, seemed like a new dog, coming outside, a little skip in her step. After the third day, she slept almost all day, a little concerning for sure. I thought maybe just trying giving some every second day instead but that didn’t change anything. I’m just new to this, so I suspect it might take more time to train “me”to tweak it just right for her weight. I’m not giving up on this. Seeing that first day I gave her some, gave me some peace of mind that I was relieving any pain she was having, so I will continue and cross my fingers for my fur baby. If she continues to just sleep all day with the oil, then I’m defeating the purpose I think.
