I'm using this for my older dog with cancer to keep her comfortable. It works better than Tramadol or Gabapentin, at this point, which have given her digestive side effects that make her sicker and knock her out for long periods of time. My vet tried to challenge me about the use of CBD but nothing can change the experience I'm seeing with my beloved girl. She is calm and enjoying many more good days than bad days. We're on our third bottle of tincture and I just reordered.
