I'd never tried CBD oil (for my dogs or for myself) until a couple weeks ago. That's when I gave this product a try because it had been donated to New Rattitude through Max & Neo's donation program. My foster dog Robin underwent luxating patella surgery in January, and afterwards he stopped using that leg COMPLETELY, refused to even touch it to the floor. After a few weeks, the vet prescribed more time and more pain meds, but neither made any difference. A couple more weeks pass and I took him back again; this time they did xrays because they had no explanation for why he wasn't using the leg. That is when they discovered that his hip is out of joint on that leg, and the poor little guy needs FHO surgery! :-( So the surgery got scheduled for six weeks out and in the meantime they gave me MORE pain meds and told me to try to get him to use the leg because successful FHO surgery depends on the muscular over that hip being strong. A couple more weeks go by, with no noticeable improvement whatsoever. That is when I decided to give the CBD oil a try. My spouse and I were astounded when 36 hrs later Robin took a few steps on that leg. And the next day he was walking on it more than he was hopping. And within another day or two, he is at 98% use of that leg... and this is even before the FHO surgery! I realize that this could be total coincidence... but it doesn't seem so.
