We have a VERY ACTIVE 7 year old Border Collie who was starting to get a bit stiff in his back legs after resting. Some evenings he would be hesistant to go up the stairs or would take them very slowly. It's just go, go, go with this type of dog so it's tough to make them "take it easy or rest". To NOT run and play is torture for them. Well we are a little over 1/2 done our first bottle of the 500mg CBD and definitely notice a difference. He isn't as stiff when he gets up after resting, is taking the stairs, jumping on the couch etc, much easier and with way less hesitation than before. We will definitely continue with the oil and hope to see even more improvement. I was about to order a couple more bottles right now. (might as well save some shipping costs and order 2!) We're going to try the new bacon flavor this time! I want to add that Honest Bontanicals have been great to deal with, very professional, helpful and quick to respond when I had a question and shipping was very fast - only took a couple days to get our first order! If you are wondering if CBD oil will help your pet, I encourage you to give it a try. I was hesistant at first but so glad I gave it a try!
