My almost 12 year old cocker spaniel, has been taking the oil for about 2 months now. He most definitely has a little more spring in his step! He was very lethargic and in pain from arthritis. He didn’t want to go on his walks. I am happy to say, that he just seems a happier boy all around. He enjoys his little walks again. Yes, of course he still struggles with his arthritis, but his whole mood is so much better.
