Stopped my mastiff mix from "clearing the room". And if i forget or miss a dose, we can both smell it. At first I tried to just feed it to him, he spat it out. Then i tried to stick it down his throat, it worked but he didnt like it. Now i just stick one in a spoon of peanut butter with a dash of parsley before bed and gas is gone. Not to mention after a week his poo has firmed up consistently for the first time since I got him at 8 weeks. He's 11 months now. He's happy, and I'm happy. I am probably going to give him this forever, but as far as dog/gut supplements go, its pennies
