My 16 year old pup was pretty healthy until about 3 months ago and age caught up to her. She started by having seizures mixed with other treatable ailments, but looked like she was going downhill fast. After she healed from the other issues, I started her on the CBD oil and she is noticeably perkier, moves better, and I have not seen a seizure since. It doesn't upset her stomach or cause diarrhea, and I think she knows it helps her, she sees the bottle and wags and comes to get it without prompting. She licks it off the dropper, or eats it on a cookie/treat. If I can get her this kind of quality of life til the end, it's totally worth it.
