Within receipt of an initial bottle of softgels, I gave one 10mg softgel to my senior (14 year old) 80Lbs yellow Lab. The difference in his mobility was dramatic within 3 days. He has more flexibility and doesn't struggle to raise himself up from a laying down position. On his nightly walk, he started to gallop again and overall has way more energy. The gels made the difference, no question. Thank you AJA, will be renewing the order monthly.
