I started both my elderly, inactive dog and my 19 year Arab gelding who refused to gain weight on it at the same time. The difference in the both of them was shocking.
My elderly dog went to bouncing around like a puppy after 2 weeks on the supplement. I ran out and didn’t reorder for a bit and two weeks after we ran out she was laying around doing nothing. Got the new order, put her back on, two weeks later bouncing like a puppy again. She has since passed, but I recommend that people try your supplement with their elderly animals before giving up on them. I cannot express enough thanks for having a product that has improved the quality of life for my animals SO much.
