13 year old? Not that you can tell.....
My dog turned 13 in December, he has had YuMove supplements for around 5 years. I am always complemented on how well he looks for his age, recently diagnosed with arthritis in his right hip, I know that YuMove has helped delay the onset and will continue to help with his mobility going forward.
I would highly recommend starting supplementing your dog earlier in their life like I did since he was 2 years old, instead of leaving till their senior years when they are exhibiting signs of older age a
